It is the battery that enables your car to start every time. As you drive the car, the battery is being continually charged, so that it is fully charged for the next start. A car battery can become problematic for a number of reasons:
- Age: the battery passes it’s used by date – you will need to replace the battery.
- Leaving your headlights, interior lights or radio on, or using the air conditioner, when the engine is not running: possibly just recharge existing battery
- Alternator is not performing correctly and fails to charge the battery. The battery itself may be fine.
