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.
As a result of this current, the battery absorbs a charge and its voltage rises. The charger limits the maximum voltage to U max, a constant or temperature-dependent maximum, typically around 2.4 V per cell. Once the U max voltage is reached, typically when the battery is charged to 70–80% of its capacity, [1] the charger enters the Uo-phase ...
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 ...
A Li-ion 1.5V AA-size battery, sold by the Chinese company Kentli as "Kentli PH5" since 2014 and with similar batteries later available from other suppliers is a AA-sized battery housing containing a rechargeable 3.7 V Li-ion cell with an internal buck converter at the positive terminal to reduce the output voltage to 1.5 V. [19] The Kentli ...

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.
