I use thw wal mart deep cycles in all my equipment such as my boat,my camper,enclosed trailer,wood haulin truck,concession trailer and they work great!! I had to replace one I have had for 4 years that I never took out in the winter but lasted good. for the money and ease of replacement and availability is the reason I use em. I use caterpillar batt. in my pickup and they have awsome warranty and life I just wish they had deep cycle.
