Battery charger. 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 charging protocol—how much voltage, current, for how long and what to do when ...

Trickle charging. Trickle charging means charging a fully charged battery at a rate equal to its self-discharge rate, thus 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.
Charge pump. A charge pump is a kind of DC-to-DC converter that uses capacitors for energetic charge storage to raise or lower voltage. Charge-pump circuits are capable of high efficiencies, sometimes as high as 90–95%, while being electrically simple circuits.
A charge amplifier is an electronic current integrator that produces a voltage output proportional to the integrated value of the input current, or the total charge injected. Schematic of a charge amplifier with a piezoelectric sensor. The amplifier offsets the input current using a feedback reference capacitor, and produces an output voltage ...
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 ...
Battery regenerator. When batteries are stored in an uncharged state for an extended period, lead-sulfur deposits form and harden on the lead plates inside the battery. This causes what is known as a " sulfated battery," which will no longer charge to its original capacity. Regenerators send pulses of electric current through the battery, which ...
