Safety notes: Lithium cells should only be operated with protective electronics! Please note that lithium cells may only be used by authorized personnel. Improper handling or short circuits can lead to fire or explosion.

Additional features: Lithium-ion batteries are thermally stable and do not suffer from memory effect. They operate on the basis of lithium and are characterized by high energy density.

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 doubling it). Only lithium-ion chargers should be used for charging. However, cheap chargers may have the disadvantage of not safely shutting off after the charging process ends, continuing to charge the batteries with a small current, which can be dangerous.
