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] The charger was discontinued around 2016, [3] after Apple revised their peripherals with built ...
A mobile phone plugged in to an AC adapter for charging. 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 ...
Rechargeable battery. A battery bank used for an uninterruptible power supply in a data center. A rechargeable lithium polymer mobile phone battery. A common consumer battery charger for rechargeable AA and AAA batteries. A rechargeable battery, storage battery, or secondary cell (formally a type of energy accumulator), is a type of electrical ...
Inductive charging. The primary coil in the charger induces a current in the secondary coil in the device being charged. Inductive charging (also known as wireless charging or cordless charging) is a type of wireless power transfer. It uses electromagnetic induction to provide electricity to portable devices. Inductive charging is also used in ...
An electric battery is a source of electric power consisting of one or more electrochemical cells with external connections [1] for powering electrical devices. When a battery is supplying power, its positive terminal is the cathode and its negative terminal is the anode. [2] The terminal marked negative is the source of electrons.
Nominal cell voltage. 1.2 V. A nickel–metal hydride battery (NiMH or Ni–MH) is a type of rechargeable battery. The chemical reaction at the positive electrode is similar to that of the nickel–cadmium cell (NiCd), with both using nickel oxide hydroxide (NiOOH). However, the negative electrodes use a hydrogen-absorbing alloy instead of cadmium.
A lithium-ion or Li-ion battery is a type of rechargeable battery that uses the reversible intercalation of Li + ions into electronically conducting solids to store energy. In comparison with other commercial rechargeable batteries, Li-ion batteries are characterized by higher specific energy, higher energy density, higher energy efficiency, a longer cycle life, and a longer calendar life.
A battery management system (BMS) is any electronic system that manages a rechargeable battery (cell or battery pack) by facilitating the safe usage and a long life of the battery in practical scenarios while monitoring and estimating its various states (such as state of health and state of charge), [1] calculating secondary data, reporting that data, controlling its environment ...
