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 radios.
A Battery: Eveready 742: 1.5 V: Metal tabs H: 101.6 L: 63.5 W: 63.5 Used to provide power to the filament of a vacuum tube. B Battery: Eveready 762-S: 45 V: Threaded posts H: 146 L: 104.8 W: 63.5 Used to supply plate voltage in vintage vacuum tube equipment. Origin of the term B+ for plate voltage power supplies.
Production of some Ever Ready batteries (PP6, PP7 and PP9) continued in the UK until 1999 by Univercell Battery Company, near the old Dawley factory, using the original machinery. Univercell moved to Stafford Park 12 and was sold to the AceOn Group in 2012; AceOn continued to manufacture Ever Ready batteries for specialist applications.
The most popular method of determining an animal's location underwater requires the tag to acquire light levels throughout the day. Observing the length of the day, from when the tag observed the first light until the last light, the tag can determine its latitudinal location (with accuracy exceeding 1 degree).
Batteries Plus (stylized as Batteries+, formerly Batteries Plus Bulbs stylized as Batteries+Bulbs) is an American retail chain of 600+ franchise outlets [2] founded in 1988 that sells and recycles [3] [4] [5] batteries of varying size and voltage that provide power to operate consumer electronics, watches, cell phones, digital cameras, automobiles and other devices that require DC power.

A manual firing-pin safety is located at the left rear of the slide; putting it in the down position locks the firing pin and flipping it up to level position unlocks it. Typical to European pistols, the magazine release is heel-mounted. The magazine is single column. [1]
It was only available with a DA/SA trigger, decocker, and a manual safety. The P85 was affordable, initially retailing for just $295, about $100 cheaper than its nearest competitors. The Ruger P85 is a full-sized DA/SA alloy-framed service pistol originally designed to compete in the 1984 U.S. military pistol trials.
Diagram showing positive tip polarity on the left and negative tip polarity on the right. To read diagram: The center positive drawing on the left indicates that the center (also known as the tip) of the output plug is positive (+) and the barrel (ring) of the output plug is negative (−).
