The battery might be bad, or your alternator might also be bad. Use a battery load
tester or digital voltmeter to see if your alternator is charging the battery? The voltage
should be no more than 13.8 volts while the vehicle is running. If it's higher, your
voltage regulator is bad, and if it's not much more than the regular voltage of the 12
volt battery itself, the alternator is not doing it's job, and needs to be replaced. Good
luck.
