Product details
A high-performance high-drain cell developed in collaboration with Efest, made from a safe chemical composition (Lithium-Manganese). The manganese does not react with lithium, which gives these cells a high level of intrinsic safety. Specifically designed for battery carriers and flashlights.

Charging Method: CC-CV
Safety Notes: Lithium cells should only be operated with protective 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 memory effect. They operate based on lithium and are characterized by a high energy density.
Technical Data for "Efest Purple IMR18500 - 1000mAh 3.7V (Flat Top, unprotected)"
Normal Charge Current: 100mA/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. 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 (potentially up to double).

(CCCV = constant current, constant voltage.) The batteries must not be charged above a voltage of 4.2 volts, otherwise there is a risk of fire and explosion. It is advantageous to charge the batteries only up to approx. 4.1 volts, as this significantly increases the service life or number of charging cycles (possibly up to double). Only lithium-ion chargers may be used for charging. However, cheap chargers sometimes have the disadvantage that they do not switch off safely at the end of the charging process, but continue to charge the batteries with a small charging current, which can be dangerous. Please dispose of them as prescribed by law in the municipal collection centres or in the [usually green] containers provided for this purpose by retailers. |
