FENIX Rechargeable USB AA battery ARB-L14-1600U FEAAUSB

The Fenix ARB-L14-1600U rechargeable battery serves as an alternative to traditional AA pencil batteries. It is a Li-ion cell equipped with regulation electronics that maintains a constant output voltage of 1.5 V during discharge. Therefore, the battery is particularly suitable for devices that are sensitive to voltage and do not work properly with NiMH batteries. The battery capacity is 1600 mAh (2.4 Wh, equivalent to 2000 mAh in NiMH).

The battery can only be charged via the built-in micro-USB connector, so it can be charged, for example, from a computer, a mobile phone charger, a power bank, or other USB sources. It must not be charged in a conventional charger.

The battery has built-in protection against over-discharge and short circuit. Therefore, the battery is suitable, for example, for flashlights and headlamps, cameras, navigators, laboratory instruments, and other devices. The battery is compatible with Fenix HL23, HL50, E12, and E20 headlamps and flashlights. It is not compatible with Fenix HM23, LD41, and LD42 (due to excessive current consumption in the highest mode).

When using this battery, it is necessary to take into account that the remaining capacity cannot be determined based on the output voltage. Devices may indicate full battery capacity during operation, but they will suddenly shut down. When the battery is discharged, its voltage drops suddenly from 1.5 V to 0 V.

Battery parameters:

• Nominal voltage: 1.5 V (the battery maintains it constant until discharge)
• Capacity: 1600 mAh (2.4 Wh)
• Maximum current draw: 1.6 A (overcurrent protection activated at higher currents)
• Charging via built-in micro-USB input. Charging current: 300 mA.
• Charging time of a fully discharged battery is approximately 2.5 hours.
• Protective electronics built into the positive pole ensure protection against overcharging, over-discharge, and short circuit.
• Lifespan: 500 charging cycles
• Diameter: 14.5 mm (+/- 0.2 mm)
• Height: 50 mm (+/- 0.2 mm)
• Weight: 19 grams.
• Charging via micro-USB connector

Connect the USB cable to the side micro-USB connector, the indicator on the top of the battery will shine red during charging. It will switch to blue when fully charged.
