A car battery does not last forever, and its life can be affected by climate, driving habits, electrical demand, and maintenance. Use testing and symptoms—not age alone—to decide what to do next.
Common warning signs
- Slow cranking when starting
- Repeated need for a jump-start
- Dim lights or electrical glitches
- A battery warning light while driving
Start with a test
A battery and charging-system test can help distinguish a weak battery from an alternator, connection, or parasitic-draw problem.
Use your owner’s manual for the correct battery type and replacement requirements.
