New Hampshire Weather Is Hard on Batteries

Short trips, infrequent driving, electrical accessories, corrosion, and charging system problems can also shorten battery life over time.
If your vehicle is cranking slowly, showing warning lights, or requiring jump starts, diagnostics can help determine whether the issue is the battery, alternator, connections, or another electrical concern.

- Clicking when starting
- Battery warning light
- Repeated jump starts

How do I know if my car battery is bad?

Many batteries last between 3 and 5 years, though cold weather, heat, short trips, and charging problems can shorten battery life.
