  2. Nickel–cadmium battery - Wikipedia

    en.wikipedia.org/wiki/Nickel–cadmium_battery

    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 Duracell AA size alkaline cell, one of the many types of battery. This list is a summary of notable electric battery types composed of one or more electrochemical cells. Three lists are provided in the table. The primary (non-rechargeable) and secondary (rechargeable) cell lists are lists of battery chemistry.

  6. Battery room - Wikipedia

    en.wikipedia.org/wiki/Battery_room

    Battery rooms were used to segregate the fumes and corrosive chemicals of wet cell batteries (often lead–acid) from the operating equipment, and for better control of temperature and ventilation. In 1890, the Western Union central telegraph office in New York City had 20,000 wet cells, mostly of the primary zinc-copper type.

  7. Batteries in space - Wikipedia

    en.wikipedia.org/wiki/Batteries_in_space

    Batteries are used on spacecraft as a means of power storage. Primary batteries contain all their usable energy when assembled and can only be discharged. Secondary batteries can be recharged from some other energy source, such as solar panels or radioisotope-based power (), and can deliver power during periods when the space vehicle is out of direct sunlight.

  9. Mercury battery - Wikipedia

    en.wikipedia.org/wiki/Mercury_battery

    A different form of mercury battery uses mercuric oxide and cadmium. This has a much lower terminal voltage around 0.9 volts and so has lower energy density, but it has an extended temperature range, in special designs up to 180 C. Because cadmium has low solubility in the alkaline electrolyte, these batteries have long storage life. [4]
