Hi All,

Battery prices from Sam's Club

G29 125 AH $79.42
G27 115AH $68.87
Golf Cart 6V 220AH $71.28

Based on dual batteries this equates to:

G 29....@....250 amp/hr = $0.63 per amp hour
G 27....@....230 amp/hr = $0.60 per amp hour
Golf Cart @ 220 amp/hr = $0.65 per amp hour

Before anyone does the "old saw" that six volt batteries last longer I'll point out that my last set of 12 volt batteries are six years old and still going strong. The "secret"? A 30 watt solar system with an old style charge controller.

I'll also point out that the dual G 29 set has 12% more amp hour capacity than the "twin" six volt set.

Don

Don:

With your boondocking style and solar system you will be in a good position to test the folk wisdom that golf cart batteries will withstand many more discharge/recharge cycles than cranking, deep cycle, marine, etc. 12 volt batteries.

That said, why do golf carts all use golf cart batteries it there is no advantage to them?
