Starting in 1996, Alexa Internet has been donating their crawl data to the Internet Archive. Flowing in every day, these data are added to the Wayback Machine after an embargo period.
The most popular rechargeable batteries
are AA and AAA; these battery cells are most commonly made
of either NiCd or NiMH. NiCd (Nickel Cadmium) is the traditional
type with a relative lower capacity when compared with NiMH
(Nickel Metal Hydride, also named the Environmentally Friendly
Battery). Since Cadmium is toxic, it pollutes the environment;
therefore, NiMH is designed to replace NiCd as well as to
deliver more power.
