FORGET About "RV-Marine Batteries". That term is the biggest bit of misleading BS I have ever heard. SCAM talk.

They are NOT in any way shape or form a Deep Cycle battery.

Best advice in thie thread is going with 2 6V and reading the Battery FAQ that another memeber put up.

2 Trojan T-105 Will give you at least 420 Amp Hours.

Plenty of power for pretty much any RV and if you add a 120 or larger solar set up..you really wont have to worry aobut losing power..depending up on load of course. Its what I have run for the past number of years although this year I added an 80 to my origianl 80 watt panel...now I find in bright Sun the solar charges at a higher amp rating than plugged into shore power.

Take your time before you buy..read the FAQ..worth it...at least I thought so 8 years ago when i saw it posted here.

rgdfs,

While I agree with this member that the RV/Marine battery is not a "true" deep cycle, they can be a good value IMO depending on your needs. They can often be found for 60-70 bucks and will last 5-6 years if properly maintained in most cases. They are the most common battery used on RVs today because of the the cost/benefit they offer. I've used them for over 10 years with good results. Of course, if you need to beef up your battery bank for huge amp hrs, there are better choices. The dual 6v option is a reasonably economical way to go but the downside is if one goes south, you're left with 6 volts. With any battery you choose, there is no substitute for proper maintenance and charging otherwise the life of any battery will be dramatically shortened.
