    This battery, introduced in 1901, was very common in continental Europe until the 1970s. It usually contains three B cells in series. In Switzerland as of 2008, 4.5-volt batteries account for only 1% of primary battery sales.

    Under certain conditions, some battery chemistries are at risk of thermal runaway, leading to cell rupture or combustion. As thermal runaway is determined not only by cell chemistry but also cell size, cell design and charge, only the worst-case values are reflected here. [63]

  6. Alkaline battery - Wikipedia

    en.wikipedia.org/wiki/Alkaline_battery

    The amount of electrical current an alkaline battery can deliver is roughly proportional to its physical size. This is a result of decreasing internal resistance as the internal surface area of the cell increases. A rule of thumb is that an AA alkaline battery can deliver 700 mA without any significant heating. Larger cells, such as C and D ...
