Dead Battery - ???

[thataway]

Generally batteries capacity depend on the weight. The more lead, the more capacity. If you look at the amps for the bucks, the Optima seem to be a bit down the scale. They weigh much less than conventional batteries, and the amp hour capacity is also considerably less than conventional and AGM batteries.

Optima may have a point that the spiral wound will take vibration better than conventional batteries--but I have driven some mightly rough riding trucks, where the batteries last a long time. Same for some of our interstates, even with an RV. Personally my back pain would limit the amount of pounding that any boat of mine would endure--and I have not had failure of batteries, which I might own. This was one of the deciding factors in the decision to not buy optima (Again, I have no experience with these batteries--just based on my reading and experience with other types of batteries).
