FENIX ARE-A4 BATTERY CHARGER

The Fenix ARE-A4 is a battery charger with four independent slots, allowing you to charge, for example, a 21700 flashlight battery and AA Ni-MH batteries at the same time. The charger detects the supported battery chemistry in each slot, and you can monitor the charging of each battery separately on the LCD screen. A mains power cable with a European plug is included.

Suitable for

• Charging 18650 and 21700 lithium-ion batteries

• Charging rechargeable AA, AAA and C-size Ni-MH or Ni-Cd batteries

• Charging multiple compatible batteries of different types at the same time

• A charging station at home or in the workshop if you use multiple battery-powered devices

Why choose the Fenix ARE-A4?

• Four independent charging slots allow you to charge up to four compatible batteries at once.

• The charger selects the charging mode for the battery chemistry detected in each slot.

• The LCD screen displays the battery type and charge level and lets you view the voltage, charging current or time.

• The charger supports both mains power and a vehicle DC power source with a suitable additional cable.

Frequently asked questions

Can the ARE-A4 charge an 18650 battery and an AA Ni-MH battery at the same time?

Yes. Place the compatible batteries in separate slots. Each slot detects the battery type and controls its charging independently.

Which AA cells can be charged with the ARE-A4?

Charge AA-size Ni-MH or Ni-Cd batteries labelled as rechargeable. The choice of charging slot depends on both the cell size and battery chemistry.

Does the ARE-A4 also work in a car?

Yes. The charger has a 12–24 V DC power input. For use in a vehicle, you need to select a compatible car power cable separately.

When is the Fenix ARE-A4 the right choice?

The ARE-A4 is a good choice if you use several lights or different types of rechargeable batteries and want to charge them at the same time. If you usually charge one battery at a time and the battery has its own USB charging port, charging it directly with a cable may be sufficient for your needs.

Our recommendation

Before charging, check the battery for its chemistry and size. If you use a longer protected 18650 or 21700 battery, also check its actual length and the charging current permitted by the manufacturer. AA size alone does not indicate the cell type. Choose an AA cell for charging that is clearly marked as Ni-MH or Ni-Cd and rechargeable.

If a device uses a pair of batteries, keep the batteries together and charge them in separate slots at the same time. You can check the LCD screen to see which battery is fully charged and which is still charging. If you use the charger at home and in the workshop, consider whether you need mains power in both locations or a separate vehicle cable as well.

One charger for multiple batteries

The Fenix ARE-A4 is suitable for a charging station where both lithium-ion batteries and rechargeable AA or AAA batteries are used. The product code for the set with a European plug is FX-ARE-A4.
