A battery charger, recharger, or simply charger, [1] [2] is a device that stores energy in an electric battery by running current through it. The charging protocol—how much voltage , amperes, current, for how long and what to do when charging is complete—depends on the size and type of the battery being charged.
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".
The Sony Ericsson W580i is a mid range slider style mobile phone in the Walkman series. The phone was announced on 26 March 2007 and was released in early August. It is a 2.5G Quad-band (850/900/1800/1900) GSM phone with EDGE capabilities and has a 2 megapixel camera.
Battery Saver Technologies aims to maintain at least 80% of the battery's original charge capacity after 500 charge cycles. [6] Qualcomm claims Quick Charge 3.0 is up to 4–6 °C cooler, 16% faster and 38% more efficient than Quick Charge 2.0, and that Quick Charge 3.0 with Dual Charge+ is up to 7–8 °C cooler, 27% faster and 45% more ...
A rechargeable battery, storage battery, or secondary cell (formally a type of energy accumulator), is a type of electrical battery which can be charged, discharged into a load, and recharged many times, as opposed to a disposable or primary battery, which is supplied fully charged and discarded after use.
The Apple Battery Charger is a battery charger which was sold by Apple Inc. and bundled with six AA batteries. It was introduced in July 2010 and marketed as a way to charge Apple's wireless Magic Mouse , Magic Trackpad and Apple Wireless Keyboard . [ 2 ]
November 1925 magazine ad for battery eliminator. A battery eliminator is an adapter intended to allow a device intended for battery operation, such as a radio, to be operated from an AC outlet. [10] All radios, except crystal sets, used batteries until the mid- to late-1920s. [11]
Battery chargers may be strictly manual, or may include controls for time and charging voltage. Battery chargers that apply a high voltage (for example, more than 14.4 volts on a 12-volt nominal system) will result in the emission of hydrogen gas from the battery, which may damage it or create an explosion risk.
