A dead battery is the most common reason a car doesn't start, and the parts-store swap in a parking lot doesn't test whether the alternator killed it. We load-test the battery, test the alternator and starter draw, install the correct group-size AGM or flooded battery, register it to the vehicle's computer where required, and take the old one for recycling.
Signs you need car battery replacement
- Slow crank or clicking when you turn the key
- Battery warning light
- Battery is more than 4 years old
- Corrosion on the terminals
- Electronics reset or dim at start
What we do on site
- Load-test the battery and check state of charge
- Test alternator output and parasitic draw
- Install the correct battery with fresh terminals and hold-down
- Register the battery (BMW, Audi, VW, many Fords and GMs require it)
- Clear codes and confirm charging voltage
Doing this in a driveway
The classic mobile job. We come to wherever the car died — home, work, the Walmart lot — and you're driving again in under an hour.
Parts we use
AGM or flooded battery in the correct group size, terminal protectors, hold-down hardware.
Pricing: Battery cost plus a modest install; often less than a dealer and you didn't have to get the car there. Every job is quoted in writing before we start, and there's no upsell — how our pricing works.
FAQ
Car Battery Replacement: common questions
How do I know if it's the battery or the alternator?
A battery that's dead every morning but charges fine during the day is usually a battery or a parasitic draw. A battery light while driving, or a car that dies mid-drive, points to the alternator. We test both before replacing anything.
Do I need an AGM battery?
If your car came with one — most start-stop vehicles and many European cars — yes. Putting a flooded battery in an AGM car shortens its life dramatically.
Why does my battery need to be 'registered'?
Many newer vehicles adjust charging based on battery age. If you skip registration the computer overcharges the new battery and it fails early. We carry the tool to do it.
