I'm thinking of using their biggest one, rated at 925 amps to crank my
IO-540 300hp engine. I'm wondering if they are the same type of
construction as the old dry cell flashlight batteries? The type that
had that black carbon inside, which are still sold as "heavy duty" D
cells, ect. The only downside I remember about them is if a
flashlight were left on by accident, and when they fully discharged,
they would then leak a messy substance and almost ruin whatever they
were in. And when they got too old they'd do the same thing. I just
wonder if those Odyssey batteries would do that. It would really be a
mess in the airplane if they did. I like the idea of their much longer
shelf and service life. I checked Bob Nuckolls site, but there's
nothing there about them. And my hard copy of his old Aeroelectric
connection was just starting to mention the RG batteries when it went
out of press and switched to a web based system. I think the aviation
dry-cell's weren't around then. I'm wondering if they need that 13.8
charging volts like the gel cells need, or if they aren't so
demanding.
