Ok, lets cut through ‘my nonsense’ and do the math:
My two 6v Costco GC’s are rated at 210 amp/hrs per (other makes vary a bit)
Two times 210 = 420 - So you and I both agree Sir!!
BUT, once connected in series to arrive at 12v, the 420, is reduced by 1/2, so I’m now at 210 amp/hrs total...To arrive at 12v theres NO SUCH THING AS A FREE LUNCH ...
Now, to arrive at usable amp/hrs lets assume that for longivity’s sake the DOD should not go below about 50% - now were at about 105 usable amp/hrs...
But then again, this is just my opinion...
NO two 210 amp hour GC2' in serie is 210 amp hours. THE VOLTAGE DOUBLE the amp hours remain the same.
Two 130 (G-31) 12 volt batteries in PARALLEL the amp hours double (260) the voltage remains the same.
Battery 101
Now there is one other component where if you put 2 in series the value halves. but I won't even name it because you are already confused. I will only say the value that divides is NOT Voltage. NOR is it current.
