When a battery runs down, a simple recharge usually gets it going again. But repeat offenders may have internal problems or issues with the car's electrical system.
M/F When a car battery has difficulty holding a charge and begins to fail, the car may display ignition problems, dim headlights during idle or a constant dashboard warning light, according to Interstate Batteries.
M/F If a battery seems unable to hold its charge, it may have a defective cell or an electrical short that makes normal operation impossible.
M/F A battery may appear not to take a charge from a home charger when the voltage in the battery falls below the minimum level that signals the charger to engage.
Batteries and Electrical Systems
M/F Some cars require more electricity than the battery being used can handle, causing it to fail unusually quickly. A faulty car electrical system may also cause premature power drainage.
Batteries and Corrosion
M/F Battery terminals may grow dirty or develop corrosion, interfering with proper performance and causing the battery to deliver more power than the situation actually requires.
