Trojan Batteries. I had a set of t-125 on my prior TT for over 10 years and sold it with them going strong. Bought two new t125's and we dry camp all the time. Im sure Ill get at least 10 years out of this set. Best deep cycle battery on the market as far as I am concerned. They are made for use in golf carts and electric forklifts as well as heavy marine industrial use. Sure you can buy inexpensive ones but they wont last as long. Trojan Batteries are built to last. Yes they arent cheap but you do get what you pay for.
