As I. Other years, I just brought the boat battery into the basement. I
charged the battery and then attached a clearance type light to the posts
to run for 30 days...then another charge to start the monthly cycle
again. This will go on for 6 months.


"Why would you discharge the battery? Â*Hard on them to deep cycle. Â*I use to
cook the battery with the old type charger, so plugged the charger in to a
wall timer, and took the on pin off the timer, and manually turned on the
timer and it turned off in 12 hours or so. Â*Just attach the charger and
monthly let th charger run for an hour."


Don't totally discharge....light is about a dozen LCDs
Read years ago it was good to cycle the battery rather than just let it sit..
