Safety notes: Lithium cells should only be operated with protection electronics! Please note that lithium cells may only be used by qualified personnel. Improper handling or short-circuiting can lead to 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 a high energy density.

Technical specifications for "LG ICR18650E1 - 3200 mAh 3.6 V - 3.8 V lithium battery (unprotected)": Normal charge current 1550 mA, charging time at 1550 mA 3 h, fast charge current 2710 mA, charging time at 2710 mA 2.5 h, constant discharge current 620 mA, operating temperature for charging 0 °C - 45 °C, operating temperature for discharging -20 °C - 60 °C.

Notes: Charging lithium-ion batteries requires a special charger that charges the batteries according to a specific charging method. The batteries must not be charged above a voltage of 4.2 volts, as there is 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.
