A leaking AA alkaline battery. Alkaline batteries use manganese dioxide and zinc electrodes with an electrolyte of potassium hydroxide.The alkaline battery gets its name from the replacement of the acidic ammonium chloride of zinc–carbon batteries with potassium hydroxide, which is an alkaline.
Extremely high temperatures can also cause batteries to rupture and leak (such as in a car during summer) as well as decrease the shelf life of the battery. The reason for leaks is that as batteries discharge – either through usage or gradual self-discharge – the chemistry of the cells changes and some hydrogen gas is generated.
The first generation rechargeable alkaline batteries were introduced by Union Carbide and Mallory in the early 1970s. [3] [5] Several patents were introduced after Union Carbide's product discontinuation and eventually, in 1986, Battery Technologies Inc of Canada was founded to commercially develop a 2nd generation product based on those patents, under the trademark "RAM".

For instance, this 12-pack of rechargeable batteries is just $10, with a unit price of $0.86 per battery. A 12-pack from Energizer is almost double the price at $17. A 12-pack from Energizer is ...
During World War II, it was designated the Type C battery by the U.S. Navy, leading to confusion with the smaller C cell battery (BA-42). In 2007, D batteries accounted for 8% of alkaline primary battery sales (numerically) in the U.S. In 2008, Swiss purchases of D batteries amounted to 3.4% of primary and 1.4% of secondary (rechargeable) sales ...
