Battery light on and battery does not hold charge

Is the battery not holding a charge or is it being drained by something staying on? If not holding a charge then replace.....if something draining the battery look at interior lights or trunk/boot light!

Well the charge light means the alternator is not charging the battery.
You would need to get the alternator and circuits tested on the car.
It could be a bad connection somewhere or other wiring problem.

Check alternator to see if charging. Replace if necessary.

Check battery, may have broken plates and not holding charge. Replace if necessary.

The first thing to do is have the battery tested, just because you charged it doesn't mean it will stay charged if the cells are sulfated up or shorted.

Sounds like battery not holding charge. Or a light staying on, boot or glovebox? Most likely battery tho.

No, They are unrelated in that sense. But, The not charging and bad battery will affect the warning lights. Ck the charging voltageee at the battery posts, Chargr rat is between 13.6 to 24.2. iF THE BATTERY IS BAD IT PROBABLY WASTED THE ALTERNATOR hAVE BOTH BATTERY AND ALT TESTWD

chk charging noltage at battery posts. should be in 13.6 to14.2.. Is charging good at 13.8. If thar's good, your battery is not.. Your alternator won't last too long with a bad battery. good luck

HI. you may have a battery drain issue that is sapping your battery overnight.

Here is the procedure I use to isolate a battery drain. Remove negative battery cable from the battery. Using a 12-volt test light, hook one end to the negative battery post the other end to the negative battery cable you just disconnected. The test light will glow or "light" if there is a drain. If the "light or glow" is faint, that is probably normal draw for the clock or computer. If the "light or glow" is bright, then there is a large drain. That should be corrected. Now start removing and replacing the fuses one by one until the light goes out; that one will be the circuit with the drain. Remember to hold in the button in the door jam for the interior lights.

sounds like a 12V drain on the system, like a trunk or glove box light that won't shut off.> Could be many. many other reasons why. The way I would find the draining circuit would be to remove the neg cable of the battery. I then would connect a 12V test light between the neg battery TERMINAL and the neg battery CABLE. With a 12V drain the light will shine. I would install into the light a 9V battery powered recepticle to hold computer and radio station memory. Then I remove fuses 1 at a time, then reinstall, at the same time looking for the 12V light to go out. Hope this helps.
