Maybe I should investigate it further before doing it next time but it has worked well. I also hook up a black light from time to time and leave it on for a couple of days and they discharge as well. Works the same but takes a lot longer to discharge the batteries. I guess it is better to change a blacklight bulb than seals in the motor.
I just bought a new one for $700 and they're not getting any cheaper. So anything that can be done to extend the life is a good thing. It's even tougher trying to explain to the wife WHY we need it. HA! HA!
