Our Free Car Battery Testing
Fast and accurate diagnostics to confirm your battery is the problem
Voltage Testing
We measure open circuit voltage and under-load voltage to determine if your battery holds charge correctly. Normal reading is 12.6V+ fully charged, below 12.4V indicates it needs charging or replacement.
Cold Cranking Amps
We test actual CCA against the battery’s rated capacity. This shows if your battery can deliver enough power to start your engine, especially in cold weather or after sitting overnight.
State of Health
Our diagnostic equipment provides a percentage score showing your battery’s overall condition. Below 70% typically indicates replacement is needed soon to avoid being stranded.
Alternator Testing
We check your alternator output voltage and amperage. A failing alternator will kill a new battery quickly, so this test is essential before recommending battery replacement.
We only recommend replacement if genuinely needed. If your battery is healthy or just needs charging, we’ll tell you—no pressure sales.

Do I need an appointment for battery testing?
No appointment needed for in-store testing—just drive in during business hours (Mon-Sat 7am-6pm, Sun 8am-4pm). For mobile testing at your location, schedule a service call and testing is included free.
How long does a battery installation take?
If your battery fails testing, we’ll provide honest recommendations. We explain what’s wrong, what battery you need, and give you an upfront quote. There’s no pressure—you can decide whether to replace immediately, later, or elsewhere.
Do you test the alternator too?
Yes, every battery test includes a free alternator and charging system check. We test alternator voltage output and amperage. A failing alternator will kill a new battery quickly, so this is an essential test we always perform.
Can you test my battery at home or work?
