Lithium Ion (Li-ion) batteries have increased capacity and are very lightweight. Their nominal voltage is 3.7V. Nickel Metal Hydride (NiMH) batteries offer high capacity (over twice the amount of Nickel Cadmium (NiCd) batteries), quick charging capabilities and great reliability. They are especially good for high drain applications like digital cameras and motor toys. They are also suitable for CD players, MD players, and MP3 players etc. The nominal voltage of NiMH batteries is 1.2V. Nickel Cadmium (NiCd) batteries have a longer cycle life, though shorter run-time than NiMH batteries. They are the most cost effective rechargeable batteries and can last up to 1000 charges. They are hardy and can withstand very low temperatures and rough use. Like all rechargeable batteries, NiCd batteries need to be completely charged before their first use. The nominal voltage of NiCd batteries is 1.
