Common Car Battery Issues

Often, it is on-board electrical equipment that drains the battery – it may seem obvious but it’s important to switch off the lights and radio etc. when you leave your car overnight and for long periods.

Cold weather is a major cause for batteries losing their charge, so minimising the use of non essential electrical equipment during these times is always a good idea. For more information on battery cold winter care please see our article Car batteries, Cold Weather and Winter Tips and Advice

Car batteries charge themselves whilst the vehicle is being driven, but it won’t fully charge itself during short journeys. The cars alternator plays a big part in helping the battery to charge itself – but if it becomes corroded, or has a loose connection it cannot function correctly, and the battery will run flat.

If you suspect there is an issue with the alternator or starter motor, you will need to consult a professional.
