Car batteries typically last for three to five years. However, factors such as extreme temperatures, frequent short trips, and electrical system problems can shorten a battery’s lifespan.
How can I tell if my car battery is failing?
There are several signs that your car battery may be failing, including:
- Slow engine cranking: If your car’s engine cranks slowly, it could indicate a weak battery.
