Hi All,
A while back, I had purchased 2 Optima batteries (1 for my Acura and 1 for my Healey) and thought I had a failing Optima battery in my Acura and replaced it after 5 years. I had had it with Optima batteries when the Optima purchased for my Healey also started to fail shortly after and decided to call Optima and complain. Reaching an Optima technician, he explained that inactivity of the Healey allowed the battery to go down farther then could be easily recharged and to attach the battery, I believe but not sure, in parallel to a second standard battery to provide the necessary resistance needed for raise the charge sufficiently in the Optima battery. I followed his direction and I have been using my Optima battery in my Healey for the past 10 years.
If I had understood the Optima battery better, I probably would not have replaced it in my Acura.
Just a thought,
