I have a small 12v batter bank using 3 batteries connected on parallel:
100 Amp, 3 years old
120 Amp, 2 years old
70 Amp, 1 year old
I basically just add whatever 12v battery I get my hands on on parallel.
and now I'm thinking of buying a 4th battery because winter is coming (not a game of thrones reference)
but the 100 amp 3 yo battery is worrying me, I'm not sure that it's holding any charge but I worry that some energy is wasted there on internal resistance, is there any harm from keeping it or should I remove it? and if I remove it and found that it's still holding some charge, is there a way to calculate if that charge is more than what the battery wastes on internal resistance?
