First, anyone traveling this weekend I wish you a safe and fun trip.My battery is going on 3 years old and doesn't seem to maintain a charge for very long so I'm going to replace it. Any advice on what type of battery to get (deep cycle, big cranking amps, etc) and brands that have worked well for you would be greatly appreciated. I see batteries listed as rv/marine, but some seem to be deep cycle, others with large cranking amps. I would think deep cycle would be better than something with a lot of cranking amps, or something with both. But looking for advice since I don't know. Thanks

My original battery was an Interstate GRP29 which only died at about 5 years old because the GFCI my camper was plugged into tripped and I didn't find it for months. I replaced it with a Walmart Everlast (now called Everstart Maxx) which was the same Interstate battery with different stickers.It's now 5 years old and still doing fine. When it gets tired I'll probably do the same.

My Lifeline AGM batteries are 7 years old with at least a third of that time in full time use. They tested out at near 100 percent capacity. Of course, that is without any sort of maintenance or care except for trying to avoid depleting the charge more than about 50 percent.

Is this in your RV or your tow vehicle? Do you ever camp without electric or are you plugged in all the time? Do you have a huge inverter?Three years is pretty short life in my experience. I get twice that out of Rv/marine batteries. Maybe your charger needs an upgrade.

Thanks for all the input. With respect to battety life, I'm not sure what voltage pull there is without anything on. I have a small roof top solar panel that keeps the battery charged, but when I put the cover on the camper the gas sensor shows low battery after just a few days.
