6 volt battery issue question about load
so I have 2 different pairs of 6 volt batteries on my toyhauler. one set from Costco, the golf cart bats, with a date on them of 4/12. they had been sitting in my garage for about a year-year and a ...

I don't know how this get's in the DIY category but it is. Also I don't know how so much misinformation on batteries is given here. Two 6V batteries in series does NOT double the current capacity, it double the voltage. Two 12V batteries (if the same AH rating) double the current available. Also the maximum drain you should attempt before killing the battery is defined by Peukerts Law (about a 20 hour drain amount). So a 200AH rating should give a max drain value of 10A - DC amps that is. Ten amps of DC will convert to 1A of AC power (P=IE must be equal for supply and drain). 10 X 12= 120 so 1 X 120= 120. If you are drawing 7A AC you are killing your batteries right off! That equals 7 X 120 = 840 so 840/12= 62 AMPS DC!! An inverter providing that much power needs more batteries to supply it (about 6 in this case).
