The manual for the battery indicates that the battery has a self-maintenance function where after a month of not being used it will discharge to 30% of its capacity and go to sleep. The manual for the charger seems to indicate that the battery needs to be on the charger for the self-maintenance function to be performed. So, does the battery need to be on the (plugged-in) charger for the self-maintenance function to be performed?
A related question regarding charging: It seems that the battery is best left in a partially charged state for longevity given the self-maintenance function that exists. Would it then be best for longevity to only charge the battery right before mowing leaving it in a depleted state most of the time (rather than putting it on the charger right after mowing and leaving it with full charge most of the time)? Thanks.
