Technical Data for "Keeppower 18650 - 2200mAh, 3.7V Li-Ion Battery Protected":
Normal Charge Current: 1100mAh/3h
Operating Temperature Charging: 0 °C - 45 °C
Operating Temperature Discharging: -20 °C - 60 °C

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 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 number of charge cycles.
