Duracell 6 volt batteries
Looking to buy 4-6 volt batteries from Sam's Club. Has anyone purchased them and how dependable are they? Any other possibilities? Thanks for your input. Happy travels, Arnold

What I find interesting is that on these 6 volt flooded battery threads its not stated how far these batteries are discharged. Yes that's how they are rated by number of full discharge cycles.So im guessing they are drawn down to almost nothing. However what I have found using Trojan T 125s is that if you hold the discharge to no greater than 50% they keep going on and on. Sold my first TT after 10 years with two Trojans T125s, still going. Bought a new to us TT 4 years ago and its a no brainer another two. We just traded up to a fiver and I added two more. So now up to 4 Trojans 125's. I know Ill get 10 plus years out of them. I use the Trimetric 2030rv meter to let me know state of charge and just upgraded to 648 watts of solar. Its a delight not to worry about it.
Heat is a major factor when it comes to battery life. Automotive batteries only last 3-4 years in Florida, despite the brand, cost, or warranty. My garage is currently in the 90s at midnight! Golf cart batteries (4x Trojan T-1275) are the same chemistry, and suffer the same limited life due to heat.
I've been purchasing 6V golf cart batteries for my solar setup since 2006. Gone through several sets. Almost always 4-5 years of use, never longer. I also have a 48V golf cart, and have to replace those batteries every 4-5 years also.
I water my batteries monthly. I have a battery watering system on the motorhome, golf cart, and had added one to the solar battery bank shortly before moving to AGMs. None have every been as low as 50% SOT (State Of Charge). Typically never below 80%!
I'm using a Xantrex LinkPRO to monitor the SOT of the battery bank.
Last year, I finally switched over to AGM batteries for the solar setup. They are much more expensive, but are expected to last 8-10 years in this heat.
