Why batteries die faster in Southern California

Most drivers think cold weather kills batteries. Cold reveals weak batteries — heat is what kills them in the first place.

Honest lifespan in LA

3–5 years for a standard lead-acid battery. AGM batteries (in cars with start-stop) can last 4–6. Sustained 95°F+ summers cut both numbers.

Signs it's done

Slow cranking on hot starts, dashboard flicker when starting, electronics resetting, or a check-engine code for low voltage. A free load test takes 5 minutes.

Don't wait to be stranded

If yours is past 4 years and showing any symptoms, replace proactively. A planned $200 swap beats a $300 tow plus the same $200 battery.
