I would recommend a very good battery. pay the extra cash. I am not sure what i did but when i left mine on trickle charge over night i only got 1.5 hours of use out of it. it is a brand new battery from carquest. I am sure that i should get a better use rate than that.
Paul, the unit is excellent and again i thank you. question though will that pump push through 150 feet of hose and still get me 40 feet up to the peak?
