Fresno's summer heat causes battery electrolyte evaporation and plate sulfation that silently degrades your battery all summer. Most batteries that fail in winter were damaged in the prior summer and never tested. We test yours — at your location.
A battery that starts your car reliably might have 30% of its cold-cranking amps left. It'll start fine in September and leave you stranded in December. We test actual health — not just current function.
A fully charged 12V battery should read 12.6V or higher at rest. Below 12.4V indicates partial discharge; below 12.0V indicates a deeply discharged or failing battery.
We test actual CCA output and compare it against your battery's rated specification. A battery at 60% of rated CCA starts fine in warm weather and fails in cold — we catch that before winter.
41% Find IssuesBattery terminals inspected for corrosion, loose connections, and post damage. Corroded terminals cause voltage drop and starting problems that look like battery failure but aren't.
Most batteries last 3–5 years in Fresno's heat (vs. 5–7 years in moderate climates). We document manufacture date and flag batteries approaching end of service life.
Battery testing is included in every SafeAuto 100-point inspection. No extra fee, no separate appointment. Book any plan from $65/mo and your battery is tested at every visit.
