Need new batteries. Any advice?

OP you got some good advice to your question, you just need to put it in perspective for what your situation is. If you are an average camper that likes to dry camp and don’t have a lot of electrical requirements 2 6 V GC batteries wired in series is your best option. I don’t watchTV or play on my computer when I camp so just lights, water pump, a small amount of 12 volts for refer and water heater is all I need. I dry camp for 7 days and batteries are down to 50% SOC without genset recharge. I don’t need solar, AGM, or Li batteries to camp. If you full time or like to stay inside and watch TV or have greater electrical requirements that is another story. If you learn how to maintain them they will easily last 10 years. I bought my Sams Club batteries in 2007 and they still last a week of dry camping. They are 15 years old and each year I expect to replace them but are still performing well. Now having said that Sams Club and Costco change who they buy batteries from so you have to check who they are buying from. I would also check Batteries Plus they sell Duracell’s and Crown in some localities. Until Li prices come way down they make no sense for my requirements, even if they lasted twice as long as my Sams Club batteries by then we will be all be talking about a newer and better battery technology.
