I bought 32 Die-Hard deep cycle batteries 5 years ago. Big, heavy, smelly, and full of nasty stuff(?) that need a lot of attention. I knew then that today would be here and I will replace them. So new pack/old pack cost about $1900/$3200. Weight ratio is 240/1440 pounds. volume is 1/4.2. Lifetime is 20/5 years. Anybody have the comparison of round trip efficiency?
