Keeping your phone plugged in once it hits a full charge and consistently charging it to 100% keeps the battery at a high voltage, which causes chemical aging in the product, said Dibakar Datta ...
A shunt charge controller or shunt regulator diverts excess electricity to an auxiliary or "shunt" load, such as an electric water heater, when batteries are full. [7] Simple charge controllers stop charging a battery when they exceed a set high voltage level, and re-enable charging when battery voltage drops back below that level.
Some devices, when plugged into charging ports, draw even more power (10 watts) than the Battery Charging Specification allows—the iPad is one such device; [107] it negotiates the current pull with data pin voltages. [55] Barnes & Noble Nook Color devices also require a special charger that runs at 1.9 A. [108]
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.
As of late-2024, the fastest-charging EV for sale in the UK is the Lotus Eletre, which can fill its battery at up to 350 kW – conveniently, that’s also the same rate as the most powerful ...
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.

Battery-powered equipment connected to mains electricity can be kept fully charged although switched on; for example, a mobile telephone can be ready to receive calls without depleting its battery charge. It enables devices to either turn on or off into a standby state automatically without human intervention (for example, a timer or Wake-on-LAN).
