When you turn the key in the ignition, the vehicle is relying on the battery to send an electrical spark to the engine. With electricity, the combustion process begins, allowing the car to function. Additionally, the cell powers the headlights, radio, and other vital electronics. Over time, the cell’s capacity will diminish, leading to auto trouble. Here are a few signs that indicate it’s time to have an auto mechanic check the battery’s performance.

4 Signs It’s Time for a New Battery

1. Clicking Noises

If you notice a slow or unresponsive start when you turn the key, the vehicle’s starter isn’t getting enough power from the cell. This delay is typically accompanied by a clicking sound. If you own a portable car battery charger, use it at the first sign of this noise. If that doesn’t help, or you don’t have a charger, visit an auto mechanic for a new battery.

2. Frequent Jumping

Although it’s normal to need a jump if you left the headlights on overnight, you shouldn’t have to do this to start the vehicle constantly. If the battery is struggling to hold a charge and requires frequent jumping, have it replaced.

3. Dim Lights

If the battery is about to die, the headlights, as well as the light’s on the dashboard and radio, will be fainter than usual. It’s dangerous to drive with dim headlights at night or in the rain.

4. Bent or Corroded Casing

Pop the hood, and look for corrosion near the battery’s terminals, which is caused by under- or overcharging. You should also examine the case to see if it’s bent. Extreme temperatures or overcharging may cause a casing to swell. This indicates a buildup of pressure inside the battery, and using it may lead to a fire because the cell is more prone to overheating.
