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".
Charging a 12 V lead–acid car battery 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 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 vehicles, power ...
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.
However it may be less reliable as an emergency light, because the rechargeable battery it contains eventually wears out. The lithium-ion cells used are typically rated for around 500 charges. In an alternative "Clockwork Torch" design, produced by Freeplay Energy , the energy is mechanically stored in a flat spiral wound mainspring , rather ...

Battery Pack, Play & Charge Cable and Quick Charger. The Rechargeable Battery Pack is a nickel metal hydride (NiMH) battery pack, which provides up to 24 hours of continuous gaming for the wireless controller. It is an alternative to disposable AA batteries, which differ slightly in voltage and have higher disposal costs (financial and ...
A charge cycle is the process of charging a rechargeable battery and discharging it as required into a load.The term is typically used to specify a battery's expected life, as the number of charge cycles affects life more than the mere passage of time.
