What I'm replacing are two older group 27 Kirkland batteries. The only info they have, besides cranking amps, is 115 min reserve. Nothing pertaining to amps hr.
They've "worked" only in the sense that we can get by with them for a couple days but it would be nice to have some additional capacity and/or something which will hold a charge longer per the draw because we live very conservatively assuring we dont run out of battery in those couple days.
Solar in the future is possible but I cant say for sure.
As I mentioned before, I thought two 6 volts offered that advantage over two 12 volts. But if not then I've learned something valuable.
