Safety note: 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 the memory effect. They operate on the basis of lithium and are characterized by high energy density. Delivery includes: 1 x Keeppower 18500 battery PCB protected with 1500 mAh. When ordering two batteries, a battery box for 18500 batteries is included for free. Technical specifications for "Keeppower 18500 - 2000 mAh, 3.6 V - 3.7 V Li-Ion battery protected": Charge current 700 mA/3.5 h, max. charge current 1520 mA/3 h, 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. It is advantageous to charge the batteries only up to about 4.1 volts, as this significantly increases the lifespan and number of charge cycles (potentially up to doubling).
