I used an Optima in the 38 and got 10 years out of it before it died. No warning, just died. Since I was on tour and needed a battery "now" I replaced it with an O'Reilly 6v battery off the shelf. I got ten years out of it too and it was still working when I recently replaced it just because of it's age. When I converted the 53 to 12v I put it's new battery in the 38 and used the 10 year old battery out of the 38 as the core for the new 12v for the 53. The Optima has a lot of grunt but is it worth the price????? Not to me.
