That is essentially what I do with my one CPAP machine. The only time I ran the batteries down was the very first night of our first trip when I attempted to run the refrigerator on battery power. I have not repeated that mistake. Since then, I have not run short on battery power, even when our converter went bad last year. I found out what was wrong in time to purchase a battery charger and use that until we got home and I could replace the converter. |

I appreciate this discussion and did a lot of research, as we both need CPAP units, including discussing the issue with ResMed who made our units. They recommended 2 Specific Duracell 6 volt golf cart batteries (sorry I do not have the model number handy at this time).
Their reason was that those 2 units will operate our CPAPs longer than 2-12 volt batteries with less chance of dropping the batteries below 50% capacity, the units are voltage and current sensitive. I am no electrical engineer but figure these folks know what they are talking about as they have to support their units. Still appreciate the discussion, suggestions and all.

Thanks, GlueGuy
I am sure you have some good points. There is a lot of information about this subject which NAP1947 should study before deciding his course of action. I still stand by my comment that 2 - 6 volt batteries in series must be of equal capability ( same age) because if one declines, there is no more 12 volts available and you would probably have to replace the faulty one with two batteries. There is no real need to hook two 12 batteries together in parallel if a battery switch is utilized. If the battery is not a deep cycle one, it should not be run down regularly below 50% (according to some sources). Also, with them in parallel and they have been severely depleted, the initial charge amperage starting the vehicle may blow the alternator protection on the line to the batteries. The result of this would be no battery power at destination since there would be no indication that this had happened. (I have had this occur.) I also do not know what the cost effectiveness is here.

And lead acid batteries is all about how many cells are in use. A 6-volt battery has 3 cells. Two of them gives you 6 cells or approximately 12 volts. A single 12-volt battery already has 6 cells, so it's 12 volts. If you are going to up the capacity, you need to run them in parallel. A simple way to compare batteries is to calculate how many watt-hours one holds. Just multiply the amp-hour rating by the voltage, and you get watt-hours. So a 6-volt battery rated at 200 amp-hours actually holds 1200 watt-hours of energy. It would be roughly equivalent to a 12-volt battery rated at 100 amp-hours.

wondering why you would go with 2 -6 volt batteries when you could install 2 - 12 volts ( for the same weight) and have more power. I bought a Perko switch which is planned to shut off both batteries, or select number 1 or number 2 for charging (switching over on a stop while travelling) I can then switch between batteries for trailer power. As you may know, if there is an imbalance between batteries, one can suck the other down and it seems your 2 - 6 volts would have to be in series to power your Pod.
Marwayne and I have both built large storage units on our Pods and that may be worth your looking at. Cheers, ilthyn

Ok if 14” is close, it appears that the tank can be moved forward about 6”, so tha5 would make my box fit.
Really getting anxious already and 5 months to go before we get it to play with.

Thank you both, I plan to get the batteries from batteries plus bulbs so will look at their boxes as well.

Plastic GC2 battery boxes can be had for around $10 each at Batteries+Bulbs. We have two and they do fit in the battery tray.
