I need help figuring what is wrong with my battery. Over night my g35's battery gets drained and just clicks but won't turn over. But if I leave the ignition in the Acc or On position without actually trying to start the car(I leave it on for about five minutes) The engine turns overs. Anyone have the same problem?

 

How are your connections on the battery? Are the terminals tight? Are they clean?

 

connectors and terminals are in good condition and also tight. since ive posted this the car is no longer dead in the morning but it is a lil slugish when starting.

 

How old is your battery?

I'm going to guess it's nearing end-of-life

 

It's about 4-5 yrs old.

 

Get it tested
