carbon-zinc battery
A carbon-zinc battery is a primary battery (non-rechargeable) commonly used in low drain consumer applications, such as clocks, calculators, and garage door openers. Carbon-zinc batteries are available in the same sizes as the alkaline and manganese dioxide ("AA", "AAA", 9-volt, "C", "D") varieties. They are one of the most widely used dry primary batteries because of their low cost and reliable performance.
