Nicad Batteries: A type of dry cell battery that can be recharged an almost indefinite amount of times. Improper handling of nicads will result in battery "memory", which will impede full charging.
NiCad batteries - Nickel cadmium batteries are losing favor as a power source for personal electronics because of the frequent need for recharging.
They are rechargeable like Nicad batteries but they are safe to throw away in landfills. They also do not exhibit the "memory" effect that Nicad batteries have shown to exhibit. They need chargers that are specifically made for NiMH batteries.
NiCad batteries have a memory, so they need to be run all the way down before recharging. Otherwise, they will begin to run out of power sooner.
An alternative power source that is typically rechargeable as a complete battery pack for some digicams. Although Lithium ION batteries cost more than NiCad batteries, they offer many advantages

NiCad _ an abbreviation for nickel cadmium _ are more temperamental, creating a "memory effect" if not charged properly. NiCad batteries will lose their capacity over time, so if given the choice, choose NiMH or lithium ion batteries.
Note, however, that NiCad batteries can't store as much power as alkaline batteries so you'll have to replace them more often. Another alternative is an external battery pack, though they tend to be large and cumbersome.
