As you would expect from Fenix, these batteries meet high quality standards, equipped with Protection/PCB with short circuit, overcharge and deep discharge protection, they are suitable for just about all torches. Designed for the Fenix PD22UE and PD25. Recommended for torches, LEDs and mech. battery packs.

Fenix 16340 Li-Ion battery PCB protected (positive terminal elevated).

Please note the dimensions of the cell before buying! Due to the built-in electronics, the cell is not suitable for every application!
Height and diameter are larger than a standard 16340 cell without PCB.

Safety instructions:

Please note that removing or damaging the protection electronics (PCB) may result in short circuit, fire development or explosion.

Other features:

High quality cell with long life and high cycle stability.
Lithium-ion batteries are thermally stable and are not subject to memory effect.
They work on the basis of lithium and are characterised by a high energy density.

Notes:

A special charger is required for charging lithium-ion batteries, which charges the batteries according to a special charging procedure. (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 household waste! Please dispose of them as prescribed by law at the municipal collection points or in the [usually green] containers provided by retailers.
