Product details

High-quality cells with long lifespan and high cycle stability. Recommended for modeling, industry, flashlights with deep discharge protection, battery carriers up to 15W, etc. Efest ICR 16340 V2 Gold (no PCB protection) Capacity (mAh) 850mAh min. Capacity (mAh) 780mAh Nominal voltage (Volt) 3.7V Charge termination voltage (Volt) 4.2V ± 0.05V Discharge termination voltage (Volt) 2.75V Recommended charge current (Ampere) 50 - 250mA Max charge current 500mA Positive terminal (construction) raised (Button Top) Composition (chemistry) LiCo (ICR) Protection circuit not present Diameter (mm) 16.4 mm ± 0.1 mm Height (mm) 33.80 mm ± 0.1 mm Weight (g) 20 g ± 1 g 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 on the basis of lithium and are characterized by high energy density. Technical data for "Efest ICR 16340 V2 Gold 850mAh 3.6V - 3.7V unprotected" Notes: Charging lithium-ion batteries requires a special charger that charges the batteries according to 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). Only lithium-ion chargers should be used for charging.

(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 the number of charging cycles (possibly up to double). Only lithium ion chargers may be used for charging. However, the 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.Furthermore, rechargeable batteries and batteries do not belong in the household waste! Please dispose of them as prescribed by law at the municipal collection points or in the [usually green] containers provided by the retail trade.
