What is Trickle Charging Mode?

The minimum current requirement (the lowest amount of power a device needs to draw from the battery so that it doesn''t turn off) for our battery is about 30mA to 90mA. When the required input of low-powered devices is less than the battery''s minimum current

How a battery works

The higher the power, the quicker the rate at which a battery can do work—this relationship shows how voltage and current are both important for working out what a battery is suitable for. Capacity = the power of the battery as a function of time, which is used to describe the length of time a battery will be able to power a device for.

Batteries, current, and Ohm''s law
