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 beyond a voltage of 4.2 volts, as this poses a risk of fire and explosion. It is beneficial to charge the batteries only up to about 4.1 volts, as this significantly increases their lifespan and the number of charge cycles (potentially doubling it). Only lithium-ion chargers should be used for charging. However, cheap chargers often have the disadvantage of not safely shutting off after the charging process is complete, continuing to charge the batteries with a small current.
