If you leave the lights on the battery goes down or anything else that uses the battery over night. But if that's not it, the battery is worn out and you need to buy a new one.
you have a loose ground.....wiggle the ground cable at battery, and see if you "make contact".....then tighten up accordingly..
AnswerIf its not the battery, or alternator. Check your ground wire, down by the starter, to make sure its not loose.
the ones that make their homes in the ground and are active at night
Plug it in or extra battery pack.
If it will not hold a charge it has a dead cell and must be replaced. If it is just running down overnight disconnect the ground cable in the evening to make sure something is not on pulling power from the battery.
get a higher volt battery
Some cars make the battery wildly inaccessible. but if it is in plain sight all you need to do is disconnect the terminals (ground first) remove battery hold down clamp. remove battery. On many newer cars you will want to use a battery charger to maintain power throughout this procedure to prevent stereo lock issues.

check netural safety switch. make sure u have a good clean ground to the battery. check ground at the frame.
Check the battery ground cable and make sure it is clean and making a good ground.
You need to check body to engine grounds. Then check battery to body ground. now check engine to battery ground make sure they are clean and tight. check the positive cable going from battery to starter and make sure its clean and tight I believe you'll find the problem.
