BOKA Ni-MH 9V Rechargeable Battery Data Sheets Table

Nickel metal hydride battery: Similar to a nickel-cadmium battery (NiCd) but it uses a hydride absorbing alloy for the anode, which makes it less detrimental to the environment. In addition, a NiMH battery can have two to three times the capacity of an equivalent size NiCd and the memory effect is not as significant. However, compared with lithium-ion chemistry, the volumetric energy density is lower and self-discharge is higher. It’s chemical composition is nickel for the cathode and a hydride absorbing alloy for the anode. Applications for the battery include hybrid vehicles such as the Toyota Prius, Toyota RAV4-EV all-electric plug-in Electric car, and consumer electronics. It was made available in 1983. The most advanced versions, up to 105 amp-hours, were made by a partnership between Panasonic and Toyota. These are the standard battery for all-electric EVs capable of lasting longer than the life of the vehicle while yielding a range more than 100 miles on a charge, adequate acceleration, and modest weight. 

“H” Stands for Ni-MH battery.
