   I need help for a friend that has a tab320.  she has a single 12v battery that needs to be replaced.  since I have 2 GC-6volts, I'm not current on which is the best 12v  battery .  She does about 1/2-1/2 powered campgrounds and boondocking for a couple of nights. she has a 30 amp service, a Renogy 100 watt suitcase and is not a power hog and currently has an Interstate 550 cranking amp battery that is dying. 
thanks for your help
Vann

	Cold Cranking amps is not the figure to look at. That is a measure of how fast a battery can put out power. What is needed is a 20 hour rating. That is a better measure of how much power a battery can store and release. Here is a link to batteries she could consider: https://www.batteriesplus.com/battery/rv/deep-cycle/12

	+1 The batteries needed for an RV should be deep cycle batteries, and the comparisons will be in 20 (or 24) hour amp-hour ratings.

	You might want to find a 12v flooded golf cart battery rather than a marine deep cycle battery. Marine batteries are a compromise between a deep cycle and a starting battery because they need to perform both functions, so they aren’t generally able to handle as many deep cycles as a golf cart battery will. I think Trojan makes a line of 12V golf cart batteries, among other brands.
