Rechargeable batteries save money and reduce the amount of resources needed for new batteries. One example of a rechargeable battery is the 4.8V NiMH. NiMH, nickel-metal hydride, are the primary materials the battery uses to store power. Most electrical items that use a 4.8V NIMH battery, such as cordless phones, remote control cars and transistor radios, have their own built-in chargers. If your charger is broken or if the manufacturer did not provide one, there are inexpensive charging options available at your local hardware store.

Clip the positive alligator clip attached to the charger to the positive charge of the battery. Generally, red is positive and black is negative. Check the charger model and battery to verify.
Clip the negative alligator clip attached to the charger to the negative charge of the battery. Squeeze the ends of the alligator clip and place the clips between the negative charge section.
Plug in the charger's power cord into an electrical socket.
Set the timer for 13 hours and wait for the battery to charge.
Check the battery after 13 hours. If the LED light on the charger reads full, disconnect the clips. If the LED light on the charger does not read full, continue to charge and set the timer for two hours. Disconnect the alligator clips after two hours. These batteries should not charge for more than 15 hours. They can overheat and cause permanent damage to the batteries.
