The SVR batteries I mentioned on the list awhile back are superior
to both the Odyssey and the Panasonic batteries in cranking ability.
http://www.svrbatteries.com/download.html#
Model Cold Cranking Amps Amp-hrs weight (lbs) Max amps
SVR-14 250 CCA 14 11.5 850
SVR-20 300 CCA 18 15
SVR-18 350 CCA 22 17
PC-680 280 CCA 16 14 680
Electric drag racers, like myself, search for batteries that will
put out THE most power per pound. The SVR-14 will put out more than 850
amps without sagging below 7 volts. The Battle Bot competitors use this
brand of battery too. You can get them at a very reasonable price from
<evparts.com>. They are cheaper, from this source, than the PC-680.
The CCA test is based on delivering the CCA at zero F for 30
seconds without sagging below 7.2 volts. In reality, a healthy engine takes
less than 5 seconds to start, even in cold weather. If you think about it,
the "pulse" amps are more important than the CCA because if you can deliver
higher voltage in the beginning, you don't need to crank the engine for
very long. With a given starter amperage load, the SVR-14 is going to
deliver more voltage, will thus spin the starter faster and start it
quicker than the PC-680.
If anyone in the Denver area would like to try out an SVR-14, I'd
be happy to lend them one for a comparison test, as long as I get it back.
