  2. Alkaline battery - Wikipedia

    en.wikipedia.org/wiki/Alkaline_battery

    Compared with zinc–carbon batteries of the Leclanché cell or zinc chloride types, alkaline batteries have a higher energy density and longer shelf life, yet provide the same voltage. The alkaline battery gets its name because it has an alkaline electrolyte of potassium hydroxide (KOH) instead of the acidic ammonium chloride (NH 4 Cl) or zinc ...

  3. Silver oxide battery - Wikipedia

    en.wikipedia.org/wiki/Silver_oxide_battery

    Service life of several thousand hours (continuous operation) [9] Shelf stable over several years (retaining 90% of initial capacity) [10] Silver oxide cells are a primary battery and do not have a cycle life or a rate of charging and discharging. [2] Typical silver oxide cells are stable at temperatures below 100°C, at which point leakage can ...

  4. Battery leakage - Wikipedia

    en.wikipedia.org/wiki/Battery_leakage

    The practical shelf life of a Ni-MH is roughly five years. Cylindrical jelly-roll Ni-MH cells, like the ones used in 1990s laptop battery packs, discharge at a rate of up to 2% per day, while button cells like the ones used in motherboard batteries discharge at a rate of less than 20% per month.

    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.

  8. Electric battery - Wikipedia

    The term shelf life is used to describe how long a battery will retain its performance between manufacture and use. Available capacity of all batteries drops with decreasing temperature. Available capacity of all batteries drops with decreasing temperature.

  9. Self-discharge - Wikipedia

    en.wikipedia.org/wiki/Self-discharge

    Self-discharge decreases the shelf life of batteries and causes them to have less than a full charge when actually put to use. [ 1 ] How fast self-discharge in a battery occurs is dependent on the type of battery, state of charge, charging current, ambient temperature and other factors. [ 2 ]
