Why do some battery electronics use lithium ion batteries and others use nickel cadmium?
STL Biker asked:
Isn’t one type of battery better than the other? Why don’t all electronics use the better battery and which type of battery is the better battery?

You should define of ‘better’. Lithium-Ion (Li-Ion) batteries have a larger capacity per space unit (square cm, inch, whatever) but they cost more. ALso, Li-Ion batteries do not suffer from discharge ‘memory’, as ni-cads do. To keep NiCads in good condition, you have to fully discharge them before recharging. If you recharge them when they’re only half empty, they will ‘remember’ this and next time you use them their capacity will have halved. RigReference

NiCads are cheap and like providing a lot of current, which is why they are used in power tools and such. NiMH the same, except they require the added expense of a smart charger.
Lithium ion batteries are used in electronics to make them smaller and lighter than they would have to be with standard alkaline or rechagrable cells. classicsat
