Tips:

Charging lithium-ion batteries requires a special charger that charges the batteries through a special charging process. (CCCV = constant current, constant voltage.) The batteries must not be charged above a voltage of 4.2 volts, otherwise there is a danger of fire and explosion. It is advantageous to charge the batteries only to about 4.1 volts, as this significantly increases the service life or number of charging cycles (possibly up to double). Only lithium-ion chargers should be used for charging. However, cheap chargers sometimes have the disadvantage that they do not safely switch off after the end of the charging process, but continue to charge the batteries with a small charging current, which can be dangerous.

Furthermore, batteries and accumulators do not belong in the household waste! Dispose of them as required by law at municipal collection points or in the designated [mostly green] retail containers.
