   en.wikipedia.org/wiki/Battery_charger

   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.

3. Trickle charging - Wikipedia

   en.wikipedia.org/wiki/Trickle_charging

   Trickle charging is the process of charging a fully charged battery at a rate equal to its self-discharge rate, enabling the battery to remain at its fully charged level. This state occurs almost exclusively when the battery is not loaded, as trickle charging will not keep a battery charged if current is being drawn by a load.

4. IUoU battery charging - Wikipedia

   en.wikipedia.org/wiki/IUoU_battery_charging

   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 ...

   In the United States, the expected battery recycling cost (to be used for proper disposal at the end of the service lifetime) is rolled into the battery purchase price. Under the so-called "batteries directive" ( 2006/66/EC ), the sale of consumer Ni–Cd batteries has now been banned within the European Union except for medical use; alarm ...
