why does my brand new toyota camry 1993 battery uncharged overnight? its a new battery and i checked and it is good. if you drive the car everything works good if you start the car right away with the new battery. i changed the distributor. checked the starter, it runs good. i also checked the alternator. and it also works great. just anyways, i checked everything but if you leave the battery inside the car plugged in overnight, it uncharged. anyone have an idea of what there might be that takes the power from the battery?
