Fenix Rechargeable USB AA battery Fenix ARB-L14-2200U

This description has been machine translated from the original text.

The Fenix ARB-L14-2200U rechargeable battery serves as a replacement for classic AA pencil batteries. Inside it is a Li-ion cell, which is equipped with regulating electronics that holds a fixed output voltage of 1.5 V for the first 70-80% of capacity and then holds a constant 1.2 V until discharged. The battery is thus particularly suitable for devices that are sensitive to voltage rise and, for example, do not work properly with rechargeable NiMHs, or only for a short period of time. The capacity of the battery is 2200 mAh (3.3 Wh which corresponds to a capacity of 2750 mAh for NiMH).

The battery is only charged via the built-in USB-C connector, so it can be charged e.g. from a computer, with a mobile phone charger, from a powerbank or other USB source. It cannot be charged in a conventional charger!

The battery also has built-in protection against complete discharge and short-circuit(maximum constant discharge current is approx. 3 A). The battery is therefore suitable for cameras, navigation systems, laboratory instruments and other devices. The battery is also compatible with all Fenix headlamps and flashlights on AA batteries. These are, for example, the models Fenix E12, Fenix E20, Fenix LD12R, Fenix LD22, Fenix HM23, Fenix HP16R.

When using this battery, it must be taken into account that it is not possible to reliably know the remaining capacity by the output voltage. During the first 70-80%, the voltage is still constant at 1.5 V and only after that it drops to 1.2 V under load. It depends on how the instruments evaluate the voltage drop from 1.5 V to 1.2 V when the remaining battery capacity drops to 20-30%. When the battery is fully discharged, its voltage drops suddenly from 1.2 V to 0 V.

Charging via USB-C connector

Plug the USB cable into the side USB-C connector, the indicator light on the top of the battery pack will glow red during charging. When the battery reaches full charge, the light turns blue.

Notice

• Cannot be charged in conventional chargers
• Do not short-circuit the battery (do not connect the cell poles with a wire)
• Do not throw the battery into fire or water
• When using the battery, observe the safety principles
