Used to be that batteries lasted quite a while 5 years.. Just put one in another truck I own after 7 years before it failed... recently I've noticed that battery life is NOT what it used to be... Even the name brands like Interstate and Die Hard and such seem wimpy at best..
I've been told that Johnson Controls, Exide and East Penn make 99% of all batteries... And multiple persons who sell, install and stock all brands of batteries have said that the quality is poor.... Our fleet comes with Motorcraft which normally last about 2 years if we are lucky... we switched to Interstate and had more failures with Interstate than with Motorcraft. So we've moved back to Motorcraft... with all that said, I've noticed a number of RV'ers who put two 6volt batteries in series for twelve volts... are these deep cycle golf cart type batteries more powerful in Amp hours than a regular 12volt deep cycle? Maybe I'm not looking at this from the right perspective...
