        What would you like to know about Optima batteries?

        The smallest battery that they make(YT S 2.7) weighs 25 pounds. It has 510 CCA and 41 Ah. About 42 W-hr/kg. About 350 W/kg @ 0 C. This is pretty good.

        The Hawker Odyssey 680 weighs 15 lbs, has 220 CCA and 16 Ah. About 27 W-hr/kg. About 250 W/kg @ 0 C.

        The SVR-14 weighs 11.5 lbs, has 200 CCA and 14 Ah. About 32 W-hr/kg. About 306 W/kg @ 0 C.

        If the specs given reflect the actual performance of the battery, the Optima YT S 2.7 looks to be a very well designed battery. A bit heavy for an airplane, however.
