4.5, and 6 V DC). You will need 4 AA size batteries.
Insert bare ends of the jumper wire between the spring and plastic case to make a good

The following pictures show typical usage of the jumper wire for 1, 2, or 3 batteries.
Please note that some battery holders may have different connections inside. If your battery
