Safety notes: Please note that removing or damaging the protection electronics (PCB) can lead to a short circuit, fire, or explosion. Additional features: Lithium-ion batteries are thermally stable and do not suffer from memory effect. They operate based on lithium and are characterized by high energy density. Technical specifications for "Keeppower 18650 - 3400mAh, 3.6V - 3.7V Li-Ion battery protected." Normal charging current 1650mAh/3.5h. Fast charging current 2000mAh/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 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.
