I use a 29 series Walmart deep cycle (in it's 3rd year, charging it at least 150 times a year at the lowest setting), put it on a good charger as soon as I get home and I don't let the battery get lower than 50%. I also use the variable speed Endura and take my time going from place to place. I've bought a number of $200+ batteries including AGM's and they never lasted much more than a year.
