thought i'd revive this thread rather than start a new one since it has loads of info...

anyway, i think my euro's battery is starting to die after 4 years. i went away for 7 weeks and came back to a completely dead battery. i hooked it up to a charger overnight and the car fired up fine the next day, although i'm worried that the battery is on it's way to the grave.


how much voltage should a battery be holding?? i was under the assumption that 12.8V and over is what it should be if the battery is holding 80-100% of its charge.

my battery was holding 12.8V after i recharged it, but a few days later it now holds 12.45V. i played around with it for a bit and turned the radio on and the voltage dropped to 12.15V. when i switched the radio and all electrics off the battery slowly returned to it's normal state of 12.45V.


should a good and healthy battery be holding at least 12.8V or more? if you went out to your euro now with a multimeter and checked your battery, what would it read?
