What's the difference between a standard and AGM battery?

Standard lead-acid batteries use liquid electrolyte and are found in most vehicles. AGM (Absorbed Glass Mat) batteries use fiberglass mats to hold the electrolyte, making them vibration-resistant, longer-lasting, and better at handling high electrical loads. Most European vehicles (BMW, Mercedes, Audi) require AGM batteries. We carry both types.

Will my radio presets and clock reset when you change the battery?

We use a memory-saver device that maintains low-level power to your vehicle's electronics while we swap the battery. This preserves your radio presets, clock, seat memory, and other electronic settings. No reprogramming needed after we leave.

Don't Call a Tow Truck. Call Us.

There's never a good time for a dead battery. It happens when you're already late for work, standing in a grocery store parking lot with frozen food in the trunk, or staring at a car that won't crank at 6 AM on a Monday. You turn the key and get nothing — just a click, or silence, or a sluggish groan that fades to nothing. Now you're stranded.

Most people's first instinct is to call a tow truck. But a tow to the nearest shop runs $150-$300 in the Oklahoma City metro — and that's before they charge you for the battery itself, plus an hour or two of sitting in a waiting room while they get to your car. By the time you're driving again, you've lost half a day and spent twice what you needed to.

OKC Mobile Mechanic takes a different approach. We bring a fully-tested, brand-name battery directly to wherever your car is sitting. We test the entire charging system first — because sometimes the problem isn't the battery at all, it's a bad alternator or a corroded cable, and replacing the battery won't fix those. If the battery IS the problem, we install the new one, clean your terminals with a wire brush, apply anti-corrosion treatment, verify a strong start, and take the old battery with us for certified recycling. The whole thing takes about 30 minutes, start to finish, and you never have to leave your location.

A dead battery doesn't mean you need a tow truck. It means you need a mechanic who comes to you with a new battery, tests the charging system to make sure the alternator isn't the real problem, and installs the right battery with clean terminals and a proper warranty — all at your location, in under 30 minutes.

Signs Your Battery Is Failing

Most batteries last 3-5 years in Oklahoma's extreme temperatures. Here's how to tell when yours is on the way out — before you get stranded.

Slow or Labored Cranking

When you turn the key and the engine cranks slowly — a sluggish "rrr...rrr...rrr" instead of a quick snap — your battery doesn't have enough power to spin the starter motor at full speed. This is the most common early warning sign, and it gets worse with each cold morning. If you're hearing this, your battery is on borrowed time.

Clicking But No Start

A rapid click-click-click-click when you turn the key means the battery has just enough power to engage the starter solenoid but not enough to actually turn the motor. A single loud click might mean the starter itself is bad, but rapid clicking is almost always a dead or dying battery. This is the "call us now" moment.

Dashboard Battery Light

The battery icon on your dashboard is actually a charging system warning. It lights up when voltage drops below healthy levels — which could mean a failing battery, a bad alternator, or a loose connection. Either way, it needs diagnosis before you get stranded. We test all three when we arrive.

Swollen or Bloated Case

Oklahoma's summer heat literally cooks batteries from the inside. When temperatures climb past 100 degrees, the electrolyte inside can boil and cause the battery case to swell or bulge. A swollen battery is a safety hazard — it can leak acid or even rupture. If you see bloating, replace it immediately and don't try to jump it.

Dim Headlights at Idle

If your headlights look noticeably dimmer when the car is at idle but brighten up when you rev the engine, your battery isn't holding a charge properly. The alternator can keep up at higher RPMs, but at idle the weak battery drags the voltage down. This is a clear sign the battery is reaching end of life.

Corroded Terminals

White, green, or blue crusty buildup on the battery terminals indicates acid leakage from a failing seal. This corrosion creates resistance in the connection, which makes starting harder and can mimic a dead battery even when the battery still has charge. We clean terminals on every install — but heavy corrosion usually means the battery is on its way out.

Mobile Battery Service in Action

Our technicians arrive with the right battery for your vehicle, test the charging system, and have you running again in minutes.

Professional Battery Service, At Your Location

These photos show real automotive battery testing, installation, and terminal service — the same professional work our OKC Mobile Mechanic team performs every day at customer locations throughout the Oklahoma City metro.

The only difference? We do it at your location instead of in a shop bay. Same professional equipment. Same quality batteries. Same expertise. Brought directly to your driveway, parking lot, office, or wherever your vehicle happens to be when the battery dies.

Every battery install includes a complete charging system test, terminal cleaning with anti-corrosion treatment, memory-saver to preserve your electronics, and certified recycling of the old battery. No shortcuts. No "close enough." Done right, every time.

Stranded With a Dead Battery? Here's What to Do

While you wait for us to arrive, here are some practical steps to stay safe and make the process faster.

Call Us First

Call 405-351-7252 and tell us your exact location, your vehicle's year/make/model, and what happened when you tried to start. We'll have a battery ready and be on our way in minutes. The sooner you call, the sooner we arrive.

Stay With Your Vehicle

Don't leave the car unattended if you're in a public lot or on the roadside. Pop the hood so we can identify you quickly when we pull up. If you're on a highway shoulder, turn on your hazard lights and stay inside the vehicle with your seatbelt on until we arrive.

Don't Keep Trying to Start It

Repeatedly cranking a dead battery won't bring it back — it just drains what little charge remains and can damage the starter motor. If it didn't start after 2-3 attempts, stop trying. You'll make our job easier and avoid turning a battery problem into a starter problem.

Turn Everything Off

Make sure the headlights, radio, A/C, and all accessories are switched off. Even with the engine off, these can draw residual power from the battery. Turning them off ensures whatever charge remains is preserved for our diagnostic test when we arrive.

Know Your Vehicle Info

Have your year, make, model, and engine size ready when you call. This helps us bring the exact right battery. If you're not sure about the engine, check the driver's door sticker or the front of the owner's manual. We can also look it up by VIN if you have that available.

Stay Cool (or Warm)

If it's 100 degrees outside, find shade or go inside a nearby building while you wait. If it's freezing, stay in the car with warm clothing. Oklahoma weather is extreme and we don't want you suffering while we're on the way. We'll call you when we're 5 minutes out so you can meet us at the vehicle.

How Mobile Battery Service Works

From the first ring to a running engine — usually under 45 minutes total including drive time.

Call Us

Tell us your vehicle's year, make, and model. Describe what's happening — clicking, no crank, slow start, dashboard warning light, or completely dead. We'll confirm the correct battery group size and CCA rating for your car, give you a firm price over the phone (no surprises when we arrive), and schedule your visit. Most calls get same-day service.

We Come With Your Battery

Same-day delivery in most cases. Our mobile service truck pulls up to your home, office, apartment parking lot, grocery store, or the side of the highway with the correct battery already on board, plus the testing equipment, terminal cleaning brush, anti-corrosion spray, memory-saver device, and proper installation tools. Everything we need is on the truck — no trips to the parts store, no waiting around.

Test, Install, Verify

First, we hook up a multimeter to check resting voltage, then load-test the alternator output to make sure the charging system is healthy. If everything checks out, we connect the memory-saver device to preserve your radio presets and electronic settings, remove the old battery, clean the terminal posts and cable ends with a wire brush, seat the new battery properly, torque the hold-down strap, reconnect the cables, and apply anti-corrosion treatment to the terminals. Then we verify a strong start and measure charging voltage at idle (should read 13.5-14.5V).

You Drive Away

Multiple cold starts to verify the battery cranks strong every time. Voltage confirmed at proper levels. Your radio presets, clock, and seat memory are all intact thanks to the memory-saver. Old battery loaded onto our truck for certified recycling at a facility that processes lead-acid batteries responsibly. You get a multi-year manufacturer warranty on the new battery and you're back on the road — usually in under 30 minutes from the time we pulled up.

What to Expect When We Arrive

Our tech pulls up with a battery ready for your vehicle

We confirm the group size, CCA rating, and terminal configuration before we leave. When we arrive at your location, the correct battery is already on the truck. No guessing, no wrong parts.

We test the charging system before touching anything

A multimeter goes on the battery first, then a load test on the alternator. If the alternator is bad, replacing the battery alone won't solve the problem — and we'll tell you that upfront. We never sell you a battery you don't need.

We install cleanly and professionally

Memory-saver connected, old battery removed, terminal surfaces cleaned with a post brush, anti-corrosion treatment applied, new battery seated properly, hold-down strap torqued, cables reconnected. Every step matters and we don't skip any of them.

We verify and clean up

Multiple cold starts to confirm the battery holds strong. Voltage check at idle to verify alternator is charging properly. Old battery loaded onto our truck for certified recycling. Your driveway is left exactly how we found it.

What's Included in a Mobile Battery Service

We don't just swap parts and leave. Every mobile battery service is a full charging-system check designed to make sure the new battery will last.

Battery Voltage & Load Test

We test the existing battery's resting voltage and load capacity to confirm it's truly failed — not just discharged from a door left open or a trunk light.
Alternator & Charging System Load Test

A bad alternator will kill a new battery in days. We load-test the alternator output (should read 13.5-14.5V at idle) before we install anything.
Brand-Name Battery Delivery & Installation

Correct group size and CCA rating for your specific vehicle. Trusted brands with multi-year manufacturer warranties. No off-brand mystery batteries.
Terminal Cleaning & Anti-Corrosion Treatment

Battery posts and cable terminals cleaned with a wire brush, treated with anti-corrosion spray, and reconnected with proper torque. Clean connections = reliable starts.
Memory-Saver Device

A low-voltage device keeps power flowing to your vehicle's electronics during the swap. Radio presets, clock, seat memory, and ECU settings are all preserved.
Hold-Down Strap Reinstallation

The battery tie-down strap is reinstalled and torqued properly. A loose battery vibrates, damages the case, and shortens its lifespan significantly.
Post-Install Voltage & Crank Verification

Multiple cold starts to verify strong cranking. Voltage measured at idle and under load. We don't leave until we're confident the battery and charging system are both working correctly.
Old Battery Removal & Certified Recycling

Your old battery is taken with us and recycled at a certified facility. Lead-acid batteries are 98% recyclable. Zero mess, zero environmental liability for you.
Multi-Year Manufacturer Warranty

Every battery we install comes with a manufacturer warranty. If it fails within the warranty period, we come back and replace it.

What Happens If You Ignore a Weak Battery

A dying battery isn't just an inconvenience. Left unchecked, it creates a chain reaction that damages other expensive components.

Battery Weakens — Slow Cranking Begins

The battery still starts the car, but it takes longer to crank. You notice it's sluggish on cold mornings. At this point, a simple replacement fixes everything — quick, cheap, painless.

Cost to fix: $150 – $250

Battery Dies — You're Stranded

The car won't start at all. You're stuck wherever you happen to be — home, work, parking lot, or worse, the side of the road. Now you need a jump start or a mobile battery service just to get moving. If you call a tow truck instead, add $150-$300 to the total.

Cost to fix: $150 – $550 (with tow)

Repeated Jump Starts Damage the Alternator

Every time you jump-start a severely discharged battery, the alternator has to work overtime to recharge it. This puts extreme stress on the alternator's voltage regulator and diodes. After enough jump starts, the alternator starts to fail too — and now you need both replaced.

Cost to fix: $500 – $900 (battery + alternator)

Voltage Instability Damages Electronics

A dying battery causes voltage spikes and drops that modern vehicles' computers aren't designed to handle. The ECU, infotainment system, power window modules, and even the transmission control module can be damaged by unstable voltage. These repairs get expensive fast.

Cost to fix: $800 – $2,500+

The Bottom Line

A $200 battery replacement can spiral into a $2,500 repair if you wait too long. The slow cranking is your car telling you it's time. Call 405-351-7252 before the damage spreads.

Understanding Your Car Battery

Knowing the basics helps you make better decisions about when to replace and what to buy.

Why Oklahoma Is Hard on Batteries

Most people think cold weather kills batteries, and it does — cold reduces cranking power by up to 60% at 0 degrees. But heat is actually the bigger killer, and Oklahoma has plenty of both extremes.

Here's what happens during an Oklahoma summer: temperatures inside your engine bay can reach 200+ degrees. This accelerates the chemical reaction inside the battery, evaporates the electrolyte fluid (even in "sealed" batteries), and corrodes the internal lead plates. A battery that's 80% healthy in May might be at 50% by September. Then when the first cold snap hits in November and your engine needs maximum cranking power, the heat-damaged battery can't deliver it. That's when you get stranded.

The average battery lifespan nationally is 4-5 years. In Oklahoma, expect 3-4 years. If your battery is approaching 3 years old and you notice any slow cranking, dim lights at idle, or a dashboard warning light, replace it proactively before Oklahoma's weather makes the decision for you.

The Oklahoma Battery Timeline

Year 1-2

Battery is strong. No issues. Full CCA output. Starts quickly every time regardless of temperature.

Year 2-3

Summer heat has degraded internal plates. Cranking starts to slow on cold mornings. This is the ideal replacement window — before you're stranded.

Year 3-4

High risk zone. Battery can fail without warning on any cold morning, hot afternoon, or after sitting a few days. You're gambling.

Year 4+

Living on borrowed time in Oklahoma. Most batteries this old will strand you during the next temperature extreme — the first 100° day or the first freeze.

What Is CCA and Why Does It Matter?

CCA stands for Cold Cranking Amps — it measures how much power the battery can deliver at 0°F for 30 seconds. The higher the CCA, the better the battery performs in cold weather.

Oklahoma winters regularly hit the teens and single digits during ice storms. Your vehicle's engine requires a specific minimum CCA to start reliably in these conditions. Installing a battery with lower CCA than recommended is a recipe for cold-morning no-starts.

We always match or exceed the manufacturer's recommended CCA rating. For trucks and SUVs with large engines, we typically recommend going 10-20% above minimum CCA for extra cold-weather margin. The cost difference between a 600 CCA and 700 CCA battery is usually under $20 — cheap insurance against Oklahoma's unpredictable winters.

Typical CCA by Vehicle Type

Compact Cars 400-550 CCA

Midsize Sedans 500-650 CCA

SUVs & Crossovers 600-750 CCA

Trucks (Gas) 700-850 CCA

Trucks (Diesel) 800-1000+ CCA

European (AGM) 600-900 CCA

Battery Types Explained

Standard Lead-Acid (Flooded)

Most common. Found in the majority of cars, trucks, and SUVs. Liquid electrolyte, serviceable or maintenance-free. Affordable and widely available. Typical lifespan in Oklahoma: 3-4 years. This is what most vehicles need and what we install most often.

AGM (Absorbed Glass Mat)

Premium option. Uses fiberglass mats instead of liquid electrolyte. More vibration-resistant, longer-lasting, and better at handling high electrical loads from modern accessories. Required on most European vehicles (BMW, Mercedes, Audi, VW). Costs more but lasts longer — 4-6 years in Oklahoma.

Enhanced Flooded (EFB)

Mid-range. An upgraded version of standard lead-acid designed for vehicles with start-stop systems. Better cycling ability than standard batteries but less expensive than AGM. Becoming more common in newer vehicles that have automatic engine shut-off at red lights.

Jump Start vs. Battery Replacement

Not every dead battery needs to be replaced. Here's how to know the difference — and what we recommend.

When a Jump Start Is Enough

You left something on

Headlights, dome light, trunk light, or a phone charger drained an otherwise healthy battery. A jump start recharges it and you're fine. This happens to everyone once in a while and doesn't mean the battery is bad.

The car sat for 2+ weeks

Vehicles parked for extended periods slowly drain the battery through alarm systems, clocks, and computer modules. A jump followed by a 30-minute drive usually recharges it. If this happens regularly, consider a trickle charger.

It's a one-time occurrence

If the battery has been reliable and this is the first time it's died, a jump is reasonable. But if it happens twice, the battery is telling you something — it's time for a replacement.

When You Need a New Battery

It's been jumped more than twice

If you've jump-started the same battery multiple times in recent months, it's not holding a charge anymore. Each jump-start also stresses your alternator. Replace the battery before it kills the alternator too.

The battery is 3+ years old in Oklahoma

Oklahoma's heat accelerates battery aging. A 3-year-old battery that's showing any weakness is at the end of its useful life. Replacing it proactively costs $200. Getting stranded and towed costs $500+.

Visible damage: swelling, corrosion, leaking

A bloated case, heavy terminal corrosion, or acid residue on top of the battery are all signs of internal failure. These batteries are a safety risk and should be replaced immediately — don't try to jump them.

Not Sure Which You Need?

Call 405-351-7252 and describe the situation. We'll ask a few questions over the phone:

How old is the battery? — If it's under 2 years, a jump is likely fine. Over 3 years in Oklahoma? Probably time to replace.

Has this happened before? — First time? Could be a one-off. Second or third time? The battery is done.

Was anything left on? — Headlights or dome light left on overnight? A jump should fix it. Nothing left on? The battery is failing on its own.

If it does turn out to be a replacement, we'll come prepared with the right battery for your vehicle. If it just needs a jump, we can advise you on that too. No pressure, no upsell — just honest advice from an ASE certified mechanic.

Why Choose a Mobile Battery Service?

Dead batteries strand people. Calling a tow truck just adds expense and delay. Here's why mobile service makes more sense.

No Tow Truck Needed

A tow to the nearest shop runs $150-$300 in the OKC metro. That's money you could put toward a better battery. We come directly to your dead car and skip the tow entirely.

Same-Day, Under 30 Minutes

Most battery calls get same-day service. Once we arrive, the typical install is 15-30 minutes. Compare that to waiting 1-2 hours for a tow truck, then another 1-2 hours at the shop.

Charging System Tested First

We verify the alternator is healthy before installing a new battery. If the alternator is bad, a new battery will die in days. We catch that before you waste money.

Major Brand Batteries

Brand-name batteries with multi-year manufacturer warranties. We stock the correct group size for your vehicle — no "close enough" substitutions.

Recycling Included

We take the old battery with us and recycle it at a certified facility. Lead-acid batteries are 98% recyclable. Zero mess or disposal hassle for you.

ASE Certified

Professional technicians who install batteries correctly — proper torque, clean terminals, hold-down strap, memory-saver. Not auto parts store clerks.

Battery Maintenance Tips for Oklahoma Drivers

You can't prevent battery failure forever, but these habits will help you get the maximum lifespan out of every battery you install.

Park in the Shade When Possible

Oklahoma's summer heat is the #1 battery killer. Parking in a garage, carport, or even under a tree reduces under-hood temperatures significantly. Every degree matters when your engine bay is already 200+ degrees in July. Your battery can last an extra year just from staying out of direct sun.

Don't Let It Sit for Weeks

A car that sits unused for 2-3 weeks will slowly drain the battery through parasitic draw from the alarm system, clock, and computer modules. If you have a vehicle that sits, consider a battery maintainer (trickle charger). Even a 30-minute drive once a week keeps the battery topped off.

Keep Terminals Clean

Corrosion on battery terminals creates resistance that makes the starter work harder and reduces charging efficiency. A $3 wire brush and some baking soda paste once a year keeps the connection clean. Or just ask us to clean them during your next oil change — we do it for free.

Turn Off Accessories Before Shutting Down

Headlights, radio, A/C, and seat heaters all draw from the battery at startup. If they're all on when you turn the key, the starter has to compete with them for power. Get in the habit of turning everything off before you shut the engine down. It reduces startup load and extends battery life.

Test It Before Winter

Oklahoma's first cold snap in November is when most batteries die. The damage was done during summer — the heat weakened it — and the cold morning finishes it off. Get your battery tested every fall before the first freeze. We offer free battery tests during any service call. A 2-minute test can save you from being stranded on a 20-degree morning.

Replace Proactively at 3 Years

In Oklahoma's climate, a battery over 3 years old is on borrowed time. The national average lifespan is 4-5 years, but our extreme heat shortens that to 3-4. If your battery is approaching 3 years and you notice any slow cranking at all, replace it on your schedule instead of its schedule. A planned $200 replacement beats a $500 emergency tow + install.

We Deliver Batteries Anywhere in OKC

Our mobile battery service covers every zip code in the Oklahoma City metro. Whether you're stranded in a parking lot in Bricktown, stuck in your driveway in Edmond, or sitting in a campus lot at OU in Norman — we'll come to you with the right battery and have you running in under 30 minutes.

People who call us most for battery service:

Commuters whose battery died before the morning drive
College students at UCO and OU stranded on campus
Parents stuck at school pickup or soccer practice
Shoppers at malls and grocery stores with a dead car
Fleet managers who need multiple vehicles serviced on-site

When Oklahoma Batteries Fail Most

Battery failures in Oklahoma follow a predictable seasonal pattern. Knowing when to expect trouble helps you stay ahead of it.

Summer (June – September)

The silent killer. Oklahoma's 95-110°F summers don't kill batteries instantly — they slowly cook the electrolyte, corrode the plates, and weaken the internal structure. You won't notice the damage until fall or winter when the weakened battery can't deliver. Summer is when the damage happens; winter is when you feel it. If your battery is 2+ years old, get it tested before June.

Winter (November – February)

The final blow. Cold weather reduces battery capacity by up to 60% and makes engine oil thicker, which means the starter needs MORE power from a battery that has LESS to give. The first hard freeze of the season is our busiest battery day of the year. We get 3-4x the normal call volume on the first morning below 25°F. Don't wait for that morning — test now.

Spring (March – May)

The recovery window. If your battery survived winter, spring is the time to test it and replace if needed — before summer heat does more damage. Spring is our recommended proactive replacement season. The weather is mild, you're not in an emergency, and you can schedule at your convenience instead of calling us from a parking lot at 7 AM.

Fall (October – November)

The danger zone. The transition from hot to cold is when most batteries fail. The cumulative heat damage from summer meets the first cold morning, and that's the end. Our call volume for dead batteries spikes dramatically between October 15 and November 30. If you haven't tested your battery by October, you're playing roulette with your morning commute.

Common Battery Problems by Vehicle Type

Different vehicles have different battery challenges. Here's what we see most often in the OKC metro.

Sedans & Compact Cars

Honda, Toyota, Hyundai, Nissan, Kia — Typically use Group 35, 51R, or 24F batteries. Oklahoma heat degrades these smaller batteries faster, averaging 3 years in the OKC metro. Most common issue: battery dies after 2-3 summers without warning.

Trucks & Full-Size SUVs

F-150, Silverado, Ram, Tundra, Tahoe, Suburban — Need high-CCA batteries (Group 65, 34, 78) to crank big engines. Trucks with aftermarket accessories (light bars, winches, audio) drain batteries faster. Dual-battery diesel trucks are also common in OKC.

Start-Stop Vehicles

Newer Ford, Chevy, Jeep, Hyundai, Kia models — Vehicles with automatic start-stop systems require EFB or AGM batteries that can handle hundreds of engine restarts per day. Installing a standard battery in a start-stop vehicle will fail quickly. We stock the right type.

European Vehicles

BMW, Mercedes, Audi, Volkswagen — Almost all require AGM batteries and many need the battery registered to the vehicle's computer after installation. We carry AGM batteries and know the registration requirements for European makes.

Battery Replacement FAQ

Real answers to the most common questions we get about mobile battery replacement in Oklahoma City.

How much does mobile battery replacement cost in Oklahoma City?

Mobile battery replacement typically runs $150-$230 for a standard lead-acid battery installed, or $200-$350 for an AGM battery installed. This includes delivery, installation, terminal cleaning, charging system test, and disposal of your old battery. Call 405-351-7252 for a quote specific to your vehicle.

How long does a mobile battery installation take?

Most battery replacements take 15-30 minutes from start to finish. That includes testing the charging system, connecting the memory-saver, installing the new battery, cleaning terminals, and verifying everything works. You'll be driving again in under half an hour.

Do you test my alternator before replacing the battery?

Always. A bad alternator can kill a brand-new battery in days, so we load-test the alternator and charging system before every replacement. If your alternator is failing, we'll tell you before you spend money on a battery that won't stay charged. This test is included at no extra cost.

What brand of batteries do you install?

We carry trusted brand-name batteries with multi-year manufacturer warranties. We stock the most common group sizes for cars, trucks, SUVs, and vans driven in the OKC metro. If you need a specific brand or an AGM battery, let us know when you call and we'll source it.

What do you do with my old battery?

We take your old battery with us and recycle it at a certified facility. Lead-acid batteries are 98% recyclable. You don't have to lug it to an auto parts store or worry about disposal — we handle the entire process as part of the service.

Can you help if my car won't start at all?

Absolutely. Dead batteries are the #1 reason people call us. Whether you're at home, at work, in a grocery store parking lot, or stranded on the side of I-35, we'll come to you with a new battery. Call 405-351-7252 and tell us where you are.

Do you carry batteries for trucks and SUVs?

Yes. Trucks and SUVs typically need Group 65, 34, 48, or 78 batteries with higher CCA than sedans. We stock the most common truck and SUV sizes and can source specialty sizes with advance notice. F-150s, Silverados, Rams, Tahoes, 4Runners — we've got you covered.

What's the difference between standard and AGM batteries?

Standard lead-acid batteries use liquid electrolyte and work in most vehicles. AGM (Absorbed Glass Mat) batteries use fiberglass mats, making them vibration-resistant, longer-lasting, and better at handling high electrical loads. Most European vehicles require AGM. We carry both types.

Will my radio presets and clock reset?

No. We use a memory-saver device that maintains low-level power to your vehicle's electronics during the swap. Your radio presets, clock, seat memory, and ECU settings are all preserved. No reprogramming needed.

Are you available on weekends?

Yes. We work 7 days a week, 7am to 7pm, including Saturdays and Sundays. Dead batteries don't wait for Monday and neither do we. Same-day service is usually available — just call 405-351-7252.
