NiMH stands for Nickel Metal Hydride, and it is one of many types of batteries that are used in laptops. Unlike some types such as Lithium batteries, NiMH batteries require some extra care when charging. The charging proccess is the same, but whereas a Lithium battery will not charge beyond its full charge capacity, a NiMH battery can overcharge, which may shorten its life. Also, NiMH batteries heat up as they are charged and need some cooling before use.
Instructions
1. Insert the NiMH battery into the laptop. Depending on the laptop, you may need to insert the battery on the bottom or on the side of the laptop. Refer to the user's manual for specific, battery-inserting procedure.
2. Plug the laptop's power adapter into the laptop. The power adapter plug is most commonly on the back or on one side of the laptop.
3. Plug the laptop's power adapter into the wall socket. This will start the charging process. The laptop does not need to be on.
4. Cool the battery before using the laptop by unplugging the power adapter from the laptop.
