Rechargeable battery 18650, 3500 mAh (Li-Ion) - Fenix

The top-of-the-line Fenix ​​18650 3500 mAh rechargeable batteries (ARB-L18-3500) with protected electronics are based on the top NCR18650GA cells from Panasonic / Sanyo with improved LiNiCoO2 technology, which brings higher safety and longer life. Li-ion rechargeable batteries are characterized by a very high capacity, do not suffer from the memory effect or self-discharge. Li-ion size 18650 is the best choice in terms of stored energy due to the size and weight of the battery.

Fenix ​​battery protection consists of internal safety mechanisms and protective electronics. Added electronic circuits prevent overcharging the cell, its excessive discharge and against short circuit or too high current consumption. If the battery electronics evaluate that the limit values ​​have been reached, they will safely disconnect the cell.

The internal protection consists of a separator, state-of-the-art Heat Resistance Layer (HRL) and a special explosion-proof valve. In the event that the gas pressure in the cell exceeds a certain limit, the internal separator separates the electrodes inside the battery and thus de-facto interrupts the exothermic reaction and the explosion-proof valve releases the gas overpressure outside the accumulator. Thanks to the combination of electronic and mechanical (temperature and pressure) protection, Fenix ​​batteries are among the safest available Li-ion batteries.

Due to its size, the 18650 battery corresponds to about two CR123A lithium batteries, which is why it is often used in lamps as a recharging alternative to these primary cells. First check if your appliance supports this article. This battery is designed, for example, for operation in LED lamps Fenix ​​FD40, Fenix ​​LD50, Fenix ​​LD75C, Fenix ​​SD10, Fenix ​​E35, Fenix ​​PD32, Fenix ​​PD35, Fenix ​​TK09, Fenix ​​TK15C, Fenix ​​TK16, Fenix ​​TK22, Fenix ​​TK32, Fenix ​​TK35, Fenix TK75, Fenix ​​TK76.
