2. List of battery sizes - Wikipedia

   en.wikipedia.org/wiki/List_of_battery_sizes

   A common size for cells inside cordless tool battery packs. This size is also used in radio-controlled scale vehicle battery packs and some Soviet multimeters. 1 ⁄ 2-, 4 ⁄ 5 - and 5 ⁄ 4-sub-C sizes (differing in length) are also available. Soviet 332 type can be replaced with R10 (#4, 927, BF, U8) or 1.5 V elements from 3 V 2xLR10 packs ...

3. Nickel–zinc battery - Wikipedia

   en.wikipedia.org/wiki/Nickel–zinc_battery

   Nickel–zinc batteries have a charge–discharge curve similar to 1.2 V NiCd or NiMH cells, but with a higher 1.6 V nominal voltage. [5]Nickel–zinc batteries perform well in high-drain applications, and may have the potential to replace lead–acid batteries because of their higher energy-to-mass ratio and higher power-to-mass ratio – as little as 25% of the mass for the same power.

4. Nickel–cadmium battery - Wikipedia

   en.wikipedia.org/wiki/Nickel–cadmium_battery

   Thomas Edison patented a nickel– or cobalt–cadmium battery in 1902, [3] and adapted the battery design when he introduced the nickel–iron battery to the US two years after Jungner had built one. In 1906, Jungner established a factory close to Oskarshamn, Sweden, to produce flooded design Ni–Cd batteries.

5. Nickel–hydrogen battery - Wikipedia

   en.wikipedia.org/wiki/Nickel–hydrogen_battery

   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 ]

7. Electric vehicle - Wikipedia

   en.wikipedia.org/wiki/Electric_vehicle

   An electric-vehicle battery (EVB) in addition to the traction battery specialty systems used for industrial (or recreational) vehicles, are batteries used to power the propulsion system of a battery electric vehicle (BEVs). These batteries are usually a secondary (rechargeable) battery, and are typically lithium-ion batteries.
