Symptoms

Battery Loses Charge Quickly

Assuming you don't have a problem with your alternator or wires, if your battery is losing its power quickly or when the vehicle is off, the battery may be defective.

Battery Will Not Charge

Voltage or Battery Gauge is Always Low

Some vehicles have a gauge that monitors the power of the battery. If accessories are running while you are idling, the gauge may drift lower. It will go back up when you begin to move. If the gauge remains low when idling and accelerating, there may be a defective with the alternator or battery.
