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.
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, amperes, current, for how long and what to do ...
