I should add I have a goof my original post. Cold cranking amps (CCA)
per U.S. standard is 30 seconds, at 0-deg F, to maintain at least 7.2
volts. Be careful that any comparison spec is under that test. Wicks
Aircraft sells one which claims "triple the cranking power," a
phenomenal 925 "cranking amps." Dimension-wise and weight, it's about
the same as a 25 AH aircraft battery. Pure flim-flam. OTOH, Gill
Battery, on their G-25 (25 AH), says 225 CCA, 0F, 7.2V, but in a 60
second test. I don't know if that's preferred/required for aircraft
batts, but on a 30 test seconds she's probably up toward 400 CCA.
