Abstract:
1. An adapter for replacing an original battery with a replacement battery of a different type, said adapter comprising: a first pair of terminals in a configuration substantially similar to terminals of an original battery; a second pair of terminals for electrically connecting to a replacement battery; a controllable variable conductivity device coupled between one of the first pair of terminals and one of the second pair of terminals, wherein said variable conductivity device has a high conductivity when a replacement battery connected to said second pair of terminals provides electrical power to a load connected to said first pair of terminals; a conductive connection between the other of said first pair of terminals and the other of said second pair of terminals; and a battery charging control circuit coupled to said second pair of terminals for sensing the voltage therebetween for controlling the conduction of the variable conductivity device to a reduced conductivity for limiting the charging of a replacement battery when a replacement battery is connected to said second pair of terminals and a battery charging device is connected to said first pair of terminals.
