I've got just over 78K miles on it. The car won't start without a jump, and will easily start with a jump, but as soon as I disconnect the jumper cables, the voltage drops. I think the battery is the factory battery, at least I haven't had to replace it in the 2 1/2 years I've had the car. This fucking sucks. I wanted this engine to last a few more months, I had planned to swap to a B-series this spring.
