Hi Rick, Thank you for the reply. I have a JLD404 and also a programmable power supply.
Let me try to do a better job of posing the questions: What sort of initial charging procedure is best? When running the mower which is probably at 20A continuous, and perhaps with a transient peak at times of 50A, if I measure voltage, is there a lower limit I should not exceed? (what is the opposite of "exceed?") Any other helpful hints on care and feeding?
