Classification: CPC H  A | IPC A  H

Claim 4:
5. The electronic vaping device of claim 1, wherein the controller is further configured to:
enable charging of the first battery portion with a second current applied across the pair of connectors, during a first charging stage, while measuring, periodically, a second measured voltage at the pair of connectors during a first time period to obtain a second measured voltage, wherein the second current remains constant during the first charging stage,
determine whether the second measured voltage is greater than a reference voltage,
reduce the second current by a first amount, to charge the first battery portion using a third current applied across the pair of connectors during a second charging stage, when the second measured voltage is greater than the reference voltage,
measure, periodically, a third measured voltage at the pair of connectors during a second time period,
reduce the third current by a second amount, to charge the first battery portion using a reduced current, each time the third measured voltage is greater than the reference voltage, and
stop the charging of the first battery portion when the reduced current is reduced to a reference current.
