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
Photoflash battery flashbulb to provide the heavy pulse of current to set off the bulb. Photoflash battery A photoflash battery is a specialized zinc-carbon battery optimized to provide a high electric current output for a short duration of time, such as required to fire a flashbulb. Service life for this battery in flashlight service is short, since flashlights required a lower but continuous long duration current. Photoflash cells were in production during the flashbulb era, and were slowly phased out as alkaline cells came into general usage. The photoflash cell was produced as a 1.5 volt size D, C Size and AA
