Regular 3.7 V Li-ion batteries have a maximum rated voltage of 4.2 V per cell. That means, when the terminal voltage of the battery reaches 4.2 V, it is fully charged and cannot store charge beyond that. In Constant Voltage state, the same voltage is applied at a constant rate by the charger circuit at the terminals of the battery. Trying to

batteries

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.

6 FAQs about [Lithium battery constant voltage output]

What is the voltage range of a lithium battery?

It is important to note that while the nominal voltage is labeled as 3.7V, the actual voltage range can vary slightly depending on factors such as temperature, load, and state of charge. This variation is due to the chemical composition and design of lithium batteries, which allow for flexibility in their performance.

What is a constant voltage battery?

In Constant Voltage state, the same voltage is applied at a constant rate by the charger circuit at the terminals of the battery. Trying to charge the battery by applying a higher voltage than this may charge the battery fast but it reduces the battery life.
