Over-Discharged
Li-ion Battery Activation
The Ci4 is capable of activating over-discharged Li-ion batteries with a protective circuit. After battery installation, the Ci4 will test and activate the batter before charging. When a battery is detected as damaged, 3 green indicators and 1 red indicator of the corresponding slot will flash simultaneously to inform the user while the Ci4 will automatically cease the charging process of this slot.
