nickel metal hydride laptop battery
The nickel metal hydride (NiMH) laptop battery was the next step up from NiCad. NiMH batteries could hold considerably more power than NiCad, but they still had something of a memory effect -- although it wasn't as pronounced. Lithium ion (Li-Ion) is the latest technology for laptop batteries; although Li-Ion batteries hold about the same amount of power as NiMH, they are considerably lighter and far superior. The Li-Ion laptop battery doesn't have a memory effect and lasts considerably longer than its predecessors. If your laptop supports multiple types of batteries, and the Li-Ion is one of them, then you should choose the Li-Ion as the best type of battery available for your laptop.
