... Unbalanced Discharge after Overcharge When either of the battery cells is overcharged, the AIC1802 will automatically discharge the overcharged cell at about 7.7mA until the voltage of the overcharged cell is equal to the voltage of the other cell. If the voltage of the other cell is below V , the internal cell-balance “bleeding” ...

... Otherwise, overcharge release voltage protection voltage and the charging current may oscillate. In addition, if overcharge protection function occurs, AIC1802 will discharge the overcharged cell and will stop bleeding function even if the voltage is not equal to the other. The recommended resistance of R1 and R2 is from ...
