Ni–Cd batteries contain between 6% (for industrial batteries) and 18% (for commercial batteries) cadmium, which is a toxic heavy metal and therefore requires special care during battery disposal. In the United States , the expected battery recycling cost (to be used for proper disposal at the end of the service lifetime) is rolled into the ...
This is a list of commercially-available battery types summarizing some of their characteristics for ready comparison. ... Nickel–cadmium: 70–90 500 [26] Nickel ...
Rechargeable batteries in the AA size are available in multiple chemistries: nickel–cadmium (NiCd) with a capacity of roughly 600–1,000 mAh, [12] nickel–metal hydride (NiMH) in various capacities of 600–2,750 mAh [13] [14] and lithium-ion. NiCd and NiMH provide 1.2 V; lithium-ion chemistry has a nominal voltage of 3.6–3.7 volts, and ...
Rechargeable nickel–cadmium and nickel–metal hydride are far less common than other rechargeable sizes. [63] Mercury batteries of the same dimensions are no longer manufactured.

A Duracell AA size alkaline cell, one of the many types of battery. This list is a summary of notable electric battery types composed of one or more electrochemical cells. Three lists are provided in the table. The primary (non-rechargeable) and secondary (rechargeable) cell lists are lists of battery chemistry.
The first consumer grade nickel–metal hydride batteries (NiMH) for smaller applications appeared on the market in 1989 as a variation of the 1970s nickel–hydrogen battery. [27] NiMH batteries tend to have longer lifespans than NiCd batteries (and their lifespans continue to increase as manufacturers experiment with new alloys) and, since ...
