Frequently Asked Questions

How long does a car battery last?
Most car batteries last 3-5 years. Hot climates shorten battery life to 2-3 years, while moderate climates may allow 4-5 years. Short trips and frequent starting also reduce battery life.
How do I know if my car battery is dying?
Signs include slow engine cranking, dim headlights, electrical issues, the battery warning light, needing frequent jump-starts, and a swollen battery case. Most auto parts stores offer free battery testing.
