About 22% of portable rechargeable batteries sold in Japan in 2010 were NiMH. [16] In Switzerland in 2009, the equivalent statistic was approximately 60%. [17] This percentage has fallen over time due to the increase in manufacture of lithium-ion batteries: in 2000, almost half of all portable rechargeable batteries sold in Japan were NiMH. [16]
The safe temperature range when in use is between −20 °C and 45 °C. During charging, the battery temperature typically stays low, around the same as the ambient temperature (the charging reaction absorbs energy), but as the battery nears full charge the temperature will rise to 45–50 °C.

A higher-temperature process could support industrial applications. It operates at over 200 °C, reacting aluminium with steam to generate aluminium oxide, hydrogen and additional heat. [3] The ionic aluminium could be stored at the smelter. One approach charges the battery at a smelter, and discharges it wherever power and heat are needed. [3]
A rechargeable battery, storage battery, or secondary cell (formally a type of energy accumulator), is a type of electrical battery which can be charged, discharged into a load, and recharged many times, as opposed to a disposable or primary battery, which is supplied fully charged and discarded after use.
A nickel–hydrogen battery (NiH 2 or Ni–H 2) is a rechargeable electrochemical power source based on nickel and hydrogen. [5] It differs from a nickel–metal hydride (NiMH) battery by the use of hydrogen in gaseous form, stored in a pressurized cell at up to 1200 psi (82.7 bar ) pressure. [ 6 ]
The battery has a temperature characteristic very different to lithium-ion batteries. The official temperature range is -20 to 60 °C. Compared with 20 °C, the battery undergoes about a 15% reduction in available capacity at -20 °C which is not that unusual. However: at 60 °C, the battery exhibits an additional 5-10% capacity.
A Battery: Eveready 742: 1.5 V: Metal tabs H: 101.6 L: 63.5 W: 63.5 Used to provide power to the filament of a vacuum tube. B Battery: Eveready 762-S: 45 V: Threaded posts H: 146 L: 104.8 W: 63.5 Used to supply plate voltage in vintage vacuum tube equipment. Origin of the term B+ for plate voltage power supplies.
