2. Battery charger - Wikipedia

   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. IUoU battery charging - Wikipedia

   Example charging graph. On the left: per-cell quantities. On the right: example values for a 40 Ah, 6-cell (12 V) battery. Note: schematic illustration; not based on actual measurements. IUoU is a DIN-designation [1] (DIN 41773) for a lead-acid battery charging procedure that is also known as 3-stage charging, 3-phase charging, or 3-step charging.

4. Float voltage - Wikipedia

   en.wikipedia.org/wiki/Float_voltage

   Float voltage is the voltage at which a battery is maintained after being fully charged to maintain that capacity by compensating for self-discharge of the battery. [1] The voltage could be held constant for the entire duration of the cell's operation (such as in an automotive battery) or could be held for a particular phase of charging by the charger. [2]

7. Rechargeable battery - Wikipedia

   en.wikipedia.org/wiki/Rechargeable_battery

   The energy used to charge rechargeable batteries usually comes from a battery charger using AC mains electricity, although some are equipped to use a vehicle's 12-volt DC power outlet. The voltage of the source must be higher than that of the battery to force current to flow into it, but not too much higher or the battery may be damaged.
