Batteries - what kind?

[Lily&Me]

We've put in one with "845 cold-cranking amps", battery-speak and basically unintelligible to me, but reportedly a good battery. We're still here, cables didn't reach or were on the wrong side or something and had to be replaced, etc.

I expect we're going to get a bit better performance out of our coach battery when dry camping now.

Thanks for the help.

cca is starter battery terminology.

there should also be info on "rated cap. amp. hrs / 20 hr rate" and "minutes of discharge" at various loads...

my guess is this one is ~ grp 27-grp 31 size with about 100 "amp hours" of capacity...

ONLY 1/2 of which should be used before REcharge...

this means about 2-3 days/nights of USEABLE time depending on loads...

so it will still need to be recharged every 2-3 days, unless demand is kept in check.

it's NOT a good thing to let yer display drop into the RED zone without promptly REcharging...

i think.
