<<As for the grid charger- Do you run a discharge on yours and how often do you run the charger? Thanks for all the info and help. Rich (northwestIL)
Normally I run a "discharge" on the way to work using MIMA-CL and then trickle charge the battery back up at night.
However, since this summer, my battery lost quite a bit of capacity from the very hot temps, and continuing to cycle the battery to/from work, and again, trickle charge at night.
I took the battery out, cycled all the sticks, rebuilt it by replacing one low capacity stick, put it back together, and now the battery is back to it's old capacity.
I have seen posts from people buying Mike's discharger, and it's probably a great product, but with MIMA and a typical trickle charger, one can cycle the battery and make use of the discharge energy in the car, instead of wasting it heating a lamp in the garage.
Hope this helps, Jim.
