Efest Battery IMR 18350 V2 (positive pole raised)

A powerful battery cell developed by Efest, made from a safe chemical composition (Lithium-Manganese). The manganese does not react with lithium, which gives these cells a high level of inherent safety. Specifically designed for battery carriers and flashlights.

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 circuits 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.

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 doubling). Only lithium-ion chargers should be used for charging.
