Nickel oxyhydroxide battery cells. Nickel oxyhydroxide battery Nickel oxyhydroxide battery (abbr. NiOx, IEC code: Z) is a type of primary cell. It is not rechargeable and must be disposed after a single use. NiOx batteries can be used in high-drain applications such as digital cameras. NiOx batteries used in low-drain applications, have a lifespan similar to an alkaline battery. NiOx batteries produce a higher voltage (1.7V) than alkaline batteries (1.5V) which can cause problems in certain products, such as equipment with incandescent light bulbs (such as flashlights/torches), or devices without a voltage regulator. The nickel oxyhydroxide cell is different from a standard alkaline
Eveready Battery Company The American Ever Ready Company became part of National Carbon Company. Hubert stayed on as the president. The trademark was shortened to "Eveready". In 1917, National Carbon Company merged with Union Carbide to form the Union Carbide and Carbon Company. From 1917 until 1921, Eveready used the trademark "DAYLO" for their flashlights and on their batteries. In 1957, employees Lewis Urry, Paul Marsal and Karl Kordesch invented a long-lasting alkaline battery using a zinc/manganese dioxide chemistry while working for Union Carbide's Cleveland plant. The company did not aggressively market the invention, however, and instead continued to market the zinc-carbon battery.
