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