[bret a ewing]

I am on my second set of Gill aircraft batteries in 4 years. Not crazy about them and will probably mount one battery in the trunk when they expire. They aint cheap either. It is critical that these batteries are kept at a charge level of +12.3 volts. Once they drop below that level these batteries are very susceptible to sulfiding resulting in very limited amp storage capability. They can sometimes be partially brought back with a heavy dose of high amp charging to "burn" off the sulfur layer but the the batteries never regain their full storage capability.
Nothing beats an Optima with 2/0 cable.
