We go beyond a simple battery test, inspecting key components like:

• Your battery's voltage and Cold Cranking Amps (CCA)

• The health of your alternator and charging system

• Starter connections, belts, and terminals

• The security of your battery tray and hold-downs

• We can also perform Battery Management System (BMS) resets for modern vehicles.

We take extra care to protect your vehicle's factory settings. Our technicians use a memory saver to prevent issues with anti-theft radios or security systems, so everything works just as it did when you brought it in.
