How to discharge EB70 properly

I know there is a lot of topics about but I want to know the rules or instructions how to discharge it properly.

So I want to know:
When I see a red icon with battery should I stop to use EB70 or should I wait until it stop charging devices at all?
Is it safe to discharge it fully?

Thank you

For the longest battery life, it is best not to fully discharge the battery on a regular basis. It is safe however to fully discharge the battery. Upon a full discharge it is important to perform a recharge as soon as possible to insure the battery voltage does not drop lower to a point that will not allow the battery mgt. system to initiate and begin charging. It is not necessary to fully charge after depleted, but to just make sure the battery is not allowed to remain in the fully discharged state.
