Battery "self-maintenance" and related charging questions

This conversation has been merged. Please reference the main conversation: Battery storage/sleep mode improvement

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.

We are so sorry that we didn't post an official answer to this question.  We must have missed it originally; please accept our apologies. The battery does not need to be in the charger for the self-maintenance function to activate.  If you just leave it on the shelf at normal room temperature for more than a month, it will automatically self-discharge. For your second question: with normal mowing season use, there is no need to discharge the battery between uses. Thanks for your questions.
