Signs of a wrong car battery

You’ll notice signs of a wrong battery if your car is struggling to start. The engine will crank but not turn over, as the battery isn’t receiving enough power to fire the spark plugs.

Other signs include dim headlights or lights that flicker when the engine is running. If the vehicle is regularly jump-started, it could be a sign that the battery isn’t able to hold a charge or is draining too quickly.

The battery should be checked for corrosion around the posts and cables, as this can cause a poor connection, reducing the battery’s power output. The life of a battery can also be reduced if it’s not being charged correctly, so it’s important to ensure that the alternator is functioning correctly.
