6 volt battery

Sound Guy,

I agree with what you said, but I should have been more clear with my question. My camper will be parked unused for a week at a race track while we are away. My current 12 volt battery will not hold up for that time period when the refrigerator is running on propane. Just want to know if 6 volt batteries have a longer draw life the 12 volt.

If you are not in it, then why have the detectors on, the radio in standby mode...I would pull those fuses. Then the fridge will make it one week.

Now we understand your actual goal here I'd agree with the above - shut everything off except the fridge, in fact if you're going to be doing this on a regular basis add a kill switch to devices such as the radio so you can conveniently restore power when you return. Make sure the television antenna wall plate is turned off and absolutely make sure the fridge's climate control system is turned off. I personally have little need for solar but your situation cries out for it, being away from the camper for a week at a time while the batteries are constantly being drawn down by the fridge. As for battery reserve, sure dual 6 volt GC-2s rated @ ~ 220 AH will offer much greater reserve than say a single 12 volt G27 but not necessarily much more than say a pair of 12 volt G31s ... just depends on your preference but most would probably opt for a pair of GC-2s for what you're trying to achieve.
