Some of the chargers for lithium-ion batteries use a trickle-charging as a first charging phase for very empty batteries, to "wake-up" the battery. Trickle-charging is a low current, constant current phase. After the voltage of the very empty battery has reached an upper limit for trickle charging, the pre-charge phase is started with a higher current. Allow defining the upper limit for trickle charging voltage, after which the charging should be changed to the pre-charging.
