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, introduced for early transistor … See more Historically, the now popular PP3 battery size was a member of the power pack (PP) battery family that was originally manufactured by Ever Ready in the United Kingdom and Eveready in the United States. The company says … See more Very often, a "9-volt" battery refers to the transistor radio size called PP3 or IEC 6F22 or NEDA 1604, although there are less common nine-volt batteries of different sizes. Batteries of all types are manufactured in consumer and … See more Lithium 9-volt batteries are disposable high-energy-density batteries. In the PP3 size they are typically rated at 0.8–1.2 Ah (e.g. >1.2 Ah @ 900 ohms to 5.4 V @ 23 °C for one type), about … See more • Media related to PP3 batteries at Wikimedia Commons See more The PP3 battery has both terminals in a snap connector on one end. The smaller circular (male) terminal is positive, and the larger hexagonal or octagonal (female) terminal is the … See more Most battery voltage testers and chargers that can also test nine-volt need another snap clip to hold the battery, while cylindrical batteries often share a holder that may be … See more • Battery eliminator • Battery nomenclature • List of battery sizes • List of battery types See more WebFeb 20, 2015 · For 1.5 volt alkaline batteries it is (voltage-1)*200. For 9 volt alkaline batteries it is (voltage-6)*33.3. A 1.5V battery is exhausted at 1V and a 9V battery is exhausted at 6V. A 1.5V battery has .5V of life and a 9V battery has 3V of capacity. You need to find the percentage of remaining life of that capacity.
