WHAT'S WRONG WITH MY BATTERY?
My battery never gets fully charged, even after driving.
If your battery repeatedly struggles to reach a full charge, the problem could lie with the battery itself or the vehicle's charging system.
Here are some possible causes:
1. A faulty alternator: The alternator recharges the battery while the engine runs. If it isn't producing enough voltage, the battery won't receive a full charge.
2. Short driving distances: Starting the engine uses battery power. Short trips may not give the alternator enough time to replace the energy used during starting.
3. An ageing or damaged battery: As batteries deteriorate, their ability to accept and hold a charge decreases. Internal damage or sulphation can further affect charging performance.
4. Poor electrical connections: Loose, corroded or damaged battery terminals and cables can interfere with the flow of current needed to charge the battery.
5. An electrical drain: A faulty component or electrical system that continues drawing power when the vehicle is switched off can gradually discharge the battery.
WHAT SHOULD YOU DO?
Driving more won't fix a charging problem caused by a faulty alternator, damaged battery or electrical fault. A proper battery and charging system test will help identify the cause.
With a national footprint, Battery Corp gives motorists access to experienced battery specialists across South Africa.
A complimentary test at your nearest Battery Corp branch shows whether the battery, the alternator or the connections are at fault.
