Comprehensive Guide to Lithium Battery Chargers by Voltage Range

The voltage range of a lithium battery charger is mainly determined by the type of battery and the series connection method. For example, the nominal voltage of a single lithium battery charger is usually 3.6V or 3.7V, and the full charge voltage can reach 4.2V. If the battery pack consists of multiple batteries in series, its charger must provide an output voltage that matches the battery pack. 

When choosing a lithium battery charger, you first need to clarify the operating voltage range of the battery and ensure that the output voltage of the charger meets this range. Setting the voltage of a lithium battery charger too high may damage the battery, while setting the voltage too low may not fully charge the battery. In addition, the lithium battery charger must have a certain voltage accuracy to ensure the safety of the charging process and the service life of the battery.

The battery capacity also directly affects the choice of a lithium battery charger. Large-capacity batteries require chargers that support high current output to shorten charging time, and lithium battery chargers with constant current-constant voltage (CC-CV) mode to ensure efficient and safe charging. Small-capacity batteries require low-current chargers to avoid overcharging causing battery heating or damage.
