Nine-volt battery: History, Overview & PP3 connectors

The nine-volt battery, or 9-volt battery, is an electric battery that supplies a nominal voltage of 9 volts. Actual voltage measures 7.2 to 9.6 volts, depending on battery chemistry. Batteries of various sizes and capacities are manufactured; a very common size is known as PP3 (IEC alkaline 6LR61), introduced for early transistor radios. The PP3 has a…
