Okay, long story short, I have gone through two Optima Batteries in 4 years. I am giving the batteries a benefit of a doubt and am asking is there as specific reason they can be failing on my car? Something electrically wrong? Something I can do to protect it?
First failure, bad coil, leaking battery.
Second failure you can read this post; when diagnosing, confirmed the battery would not accept the charge, confirmed bad battery.
Electrical Failure
Both failed within a couple months after the warranty expired. Hmmmmm.
