An individually adjustable automatic charging circuit for multiple batteries includes two or more charging terminals or battery seats for a single or multiple chargeable batteries with the same or different residual electric capacities, and voltage adjusting components connected across each respective pair of charging terminals or battery seats. The charging circuit is capable of individually or simultaneously initiating and completing charging of respective batteries, so that each chargeable battery can be randomly inserted for charging or removed without considering the residual electric capacity status and without affecting the charging status of other batteries.

[ What is claimed is:] [1.] A charging circuit for at least two batteries, comprising:at least two pairs of charging terminals, each of said pairs of charging terminals including a first charging terminal and a second charging terminal, said first and second charging terminals being arranged to engage respective positive and negative terminals of batteries inserted between the charging terminals for charging;a power supply for supplying charging currents to said charging terminals; anda respective voltage adjusting circuit connected between said first and second charging terminals of each of said pairs of charging terminals, said voltage adjusting circuit causing said charging currents to vary for each pair of charging terminals depending on electric capacities of the individual batteries inserted between the terminals,thereby permitting individually batteries to be individually inserted and removed at random without regard to battery capacity, without requiring the batteries to be first be discharged for simultaneous charging, and without affecting charging of other batteries by the charging circuit.
