   Alkaline carbon‑zinc (3 cells): 4.5: Two 6–7 mm wide metal strips +: shorter strip −: longer strip: H: 67 L: 62 W: 22 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 ...

4. 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 ...
