Charge time current
WebIn general, charge Q is determined by steady current I flowing for a time t as Q = I t. Constant, instantaneous and average current are expressed in amperes (as in "the charging current is 1.2 A") and the charge … WebTime control for charging of common 9V rechargeable batteries ( NiCd and NiMH 9 V batteries.) The timer takes longer because these can only be charged at much lower current rate of 0.1C or 1/10C ( mAhr/10 = charging time in hours ) of their mAh capacity value. Usually between 30 mA to 100 mA depending on the 9V battery capacity in mAh.
