How to Discharge NiMH Batteries

NiMH batteries are Nickel Metal-Hydride batteries, which are one of several types of rechargeable batteries on the market today. These batteries, when given the proper care and maintenance, can last up to around 1,000 charges. NiMH batteries come in all different sizes, including AA, AAA, C, D, and 9V. Discharging these batteries is simple enough, you just have to have one piece of equipment.

Things You'll Need

• NiMH batteries
• Electonic device for the batteries to run

Instructions

1. Place the batteries into the device. The device you choose depends on the size of the battery. If it is a AAA battery, the device would be a child's toy; if the batteries are AA, then the device could be a portable CD player or camera. Likewise for the other sizes of batteries.

2. Plug in the device if necessary.

3. Turn on the device and let it run until it will not turn on anymore. At this point, the batteries are discharged.
