Notes: Charging lithium-ion batteries requires a special charger that charges the batteries using a specific charging method (CCCV = constant current, constant voltage). The batteries must not be charged above a voltage of 4.2 volts, as this poses a risk of fire and explosion. It is advantageous to charge the batteries only up to about 4.1 volts, as this significantly increases their lifespan and the number of charge cycles (potentially up to double).
