Damn car wont start. Checked the battery, all full, and only 4 years old. Jumped the car and drove it around for an hour, alt read 14V the whole time. Tried to start it the next day, dead. Been on a Porsche trickle charger all week, dead. I am going to put it on a battery charger tonight, and see if the battery even holds a charge now. )(%#()%)*( damnit.

Did you load test the battery? Put a meter on it and turn the key to start. If the voltage drops below 10.5-11v you need a new battery.

If it an Optima battery and it went dead, you need a special charger or another battery in parallel to charge it
