Battery for fridge

[Hilldweller]

But maybe a yellowtop is better due to the discharge and charge, I thought red tops were start batteries?

Glen has a point; RedTops are starting batteries and not intended to deep cycle at all.

I have an ARB 50-qt fridge in my teardrop and a pair of Optima D31M Bluetops. I chose the Optimas mostly for their low internal resistence, robustness, and VERY fast recharge times.
Our style of camping usually consists of 2-4 days of basecamping and a series of short (sometimes long) hops to new locations. I wanted something that the truck's 180 amp alternator could recharge most of the time and this set-up has worked perfectly for us. I've carried a Honda-1000 genny with us but have never needed it.
In fact, the lowest that I've ever run the batteries down is to 12.7 volts and the Optimas laugh that off.

Yellowtops are the best choice if they meet your amperage requirements; their warranty is better than Bluetops and most of them are identical internally. I chose the Bluetops in that size for the increased reserve capacity --- and there's no Yellowtop that big...

Also, you might want to look at making the solar panel mobile. Attaching it to the trailer, means you always have to camp in the sun, shade is your friend, make a drop cord so you can be in the shade and the panel in the sun, it will make the female side much happier I have found.

Also, I have access to the top of the line solar batteries, made by Chairman, Concorde and Sun Saver. These are military grade solar batteries. I have group 31 batteries in towers, that have lasted 12 years. Understand that these are not economical, but they are the best on the market I think and are the bench mark for solar micro wave towers. Verizon, ATT and Sprint use this same battery type for their micro wave towers.

I do not have pricing on them currently and the manufacturer is closed down until the 11th. If you are intereseted let me know and I will get pricing. Or if you want the killer 258 amp hour one I use in my trailers, I can get you a ball park price on that to..
