Battery Service

Testing, replacement, and charging system checks.

Car Battery Service

A dead battery is the number-one cause of roadside breakdowns. Extreme heat and cold can both take a toll on your battery. We test your battery and charging system to catch problems before they leave you stranded in a parking lot or on the side of the road. If you need a replacement, we carry quality batteries for all makes and models, installed while you wait.

How Your Battery and Charging System Work

Your battery provides the initial surge of power to start your engine and runs electrical accessories when the engine is off. Once running, the alternator takes over, recharging the battery and powering your vehicle's electrical systems. A failing battery, worn alternator, or corroded connections can cause slow cranking, dim lights, or complete no-start situations. Our technicians test the entire charging circuit — battery, alternator, and starter — to identify the exact source of the problem.

Fast Battery Replacement

When your battery needs replacing, we make the process quick and convenient. We remove the old battery, clean the cable connections and terminal posts, install a fresh battery matched to your vehicle's specifications, and verify proper charging system operation. Most battery replacements take 30 minutes or less. We also recycle your old battery responsibly.

Battery Service in San Francisco

Don't wait for a no-start morning to think about your battery. San Francisco's short trips and cool, damp marine climate are surprisingly tough on batteries — lots of starts, little highway charging time, and corrosion all shorten their life. If your battery is more than three years old, we recommend a proactive load test during your next visit to our SoMa shop. Battery testing is quick, and most replacements are done in 30 minutes or less — stop by anytime during business hours.
