Hello, I have a Wayne battery back up sump pump model ESP15 and it
eats up a brand new deep cycle marine battery about every 1 - 2 years
whether it gets used or not. I think it is because the AC charger is
always plugged in and over time will "cook" the battery to death. Has
anyone else had this experience with this pump? What type of battery
is best to use in this location? Would one of the new "dry" cell
batteries work better? Would it be better to charge the battery to
full condition and then unplug the charger and check for charge
condition every week or so and charge as needed? Thanks for any
suggestions!
