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 and current, for how long and what to do when charging is complete—depends on the size and type of the battery being charged.
The DieHard brand is also used on hand tools, power tools, battery chargers, booster cables, power inverters, alkaline batteries, tires, work boots, and the batteries for Craftsman power tools. Battery chargers were initially made by Associated Equipment under the "608" model prefix, and then later Schumacher Electric under the "200" model prefix.
Modern NiMH cells were based on this design. [10] The first consumer-grade NiMH cells became commercially available in 1989. [11] In 1998, Stanford Ovshinsky at Ovonic Battery Co., which had been working on MH-NiOOH batteries since mid-1980, [12] improved the Ti–Ni alloy structure and composition and patented its innovations.

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.
Apple marketed its battery charger as environmentally friendly due to a lower standby power draw, although Massachusetts Institute of Technology engineering professor Gerbrand Ceder criticized Apple for shipping peripherals that require disposable batteries, instead of non-removable lithium-ion batteries like many of Apple's competitors.
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 ...
Inductive chargers produce more waste heat than wired chargers, which may negatively impact battery longevity. [ 14 ] [ better source needed ] An amateur 2020 analysis of energy use conducted with a Pixel 4 found that a wired charge from 0 to 100 percent consumed 14.26 Wh ( watt-hours ), while a wireless charging stand used 19.8 Wh, an increase ...
The LV battery supplies power to the electronics and accessories when the hybrid system is turned off and the high-voltage battery main relay is off. [11] [12] The traction battery is a sealed nickel-metal hydride (NiMH) battery pack. The battery pack of the first generation Toyota Prius consisted of 228 cells packaged in 38 modules, while the ...
