NiMH Battery Voltage Chart
The battery voltage remains constant, the discharge current decreases, and the power output of the battery decreases. The opposite is true when the temperature rises, that is, the output power of the battery will increase, and the temperature will also affect the transmission speed of the electrolyte.

Introduction. Various resources state that the optimal method of charging a li-ion cell -- such as one found in a mobile phone -- is to charge at a constant current (usually <1C) until a certain voltage threshold is reached, then switch to charging at a constant voltage until the charging current drops to about 0.1C, at which point the battery is fully charged.
