Please note that lithium cells may only be used by qualified 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. Technical specifications for Sanyo UR16650ZTA 2500 mAh 3.6 V - 3.7 V Li-Ion battery. Notes: 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 must not be charged beyond 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 or number of charge cycles (potentially up to doubling). 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, instead continuing to charge the batteries with a small current, which can be dangerous. Furthermore, batteries and accumulators should not be disposed of in household waste!.
