Currently I have two Interstate batteries,
cranking amps 750,
My question is.....can I put a battery from a group 29 with the 27 or should I keep them the same?
How about cranking amps, keep them the same or can I get one with higher cranking amps?
Same question with reserve capacity?
Also a completely different battery, like one from Sam's or Wal-Mart or academy, would that be ok to put with the interstate battery to get my 24 volts?
As is obvious, I know nothing about batteries so any and all input will be greatly appreciated.
