My 2001 Prius needed a jump this morning; it has been a little iffy for about two weeks.

Since the cost of a new 12v is expensive right now , I'm trying to keep it going a little longer. Does anyone know if it will cause more problems to charge the battery overnight? I might have to do this for about a week.

I also don't know why it's dead.

Right now it's at 10v.

Thanks in advance.

I use a battery tender and I also upgraded my 02 12V battery with the Optima for a Gen 2 and up. The battery tender will automatically regulate when the battery needs to be charged.
