Fenix ARE-A4 Multifunctional Battery Charger – 4-Bay Smart Charger for Li-ion & Ni-MH Batteries

Fenix ARE-A4 Multifunctional Battery Charger – 4-Channel Smart Charging

The Fenix ARE-A4 Multifunctional Battery Charger is a versatile four-channel smart charger designed to recharge multiple battery sizes and chemistries in one convenient device. Compatible with lithium-ion (Li-ion), nickel-metal hydride (Ni-MH), and nickel-cadmium (Ni-Cd) rechargeable batteries, the ARE-A4 is an excellent charging solution for professional flashlights, headlamps, camping lanterns, and other battery-powered equipment.

Featuring four independent charging bays, a high-definition LCD screen, automatic battery detection, and multiple built-in protection circuits, the Fenix ARE-A4 provides convenient and controlled charging for industrial professionals, outdoor enthusiasts, and everyday users.

Four Independent Charging Channels

The ARE-A4 allows users to recharge up to four compatible batteries simultaneously. Each charging channel operates independently, allowing different supported battery sizes and chemistries to be charged at the same time without requiring separate chargers.

This flexible design is particularly useful for professionals who rely on multiple rechargeable flashlights, headlamps, and portable lighting devices throughout the workday.

Automatic Battery Detection & Smart Charging

The Fenix ARE-A4 automatically identifies compatible battery chemistries and selects the appropriate charging mode. The intelligent charging system regulates charging voltage and current according to the battery type, eliminating the need for manual chemistry selection.

• Li-ion batteries: 4.2V / 1.0A per channel
• Ni-MH and Ni-Cd batteries: 1.5V / 1.0A per channel
• Independent charging control for each battery bay
• Automatic selection of the appropriate charging mode

Compatible Rechargeable Battery Sizes

The ARE-A4 supports a broad range of rechargeable battery sizes commonly used in Fenix lighting equipment and other compatible electronic devices.

Battery Chemistry	Compatible Sizes
Lithium-Ion (Li-ion)	10440, 14500, 16340, 18350, 18650, 21700, 26650
Nickel-Metal Hydride (Ni-MH)	AAA, AA, C
Nickel-Cadmium (Ni-Cd)	AAA, AA, C

Always verify battery voltage, physical dimensions, and terminal compatibility before charging. Certain proprietary or oversized protected batteries may not fit even when their nominal battery size is listed as compatible.

High-Definition LCD Charging Display

The integrated LCD screen provides clear information about each battery's charging progress. Users can monitor battery status and cycle through available charging information using the charger controls.

• Individual battery charging status
• Battery charge level
• Battery voltage
• Charging current
• Elapsed charging time

The display can also be switched off when illumination is not needed, making the charger convenient for use in offices, workshops, and residential environments.

Multiple Built-In Charging Protections

The ARE-A4 incorporates multiple electronic protection systems to help reduce common charging hazards and protect compatible rechargeable batteries during operation.

• Short-circuit protection
• Over-current protection
• Over-voltage protection
• Reverse polarity protection

AC & DC Power Compatibility

The Fenix ARE-A4 supports both AC and DC power sources, providing flexibility for charging batteries at home, in the workplace, or in a compatible vehicle setup. The included AC power cable allows convenient connection to a standard electrical outlet.

A compatible DC vehicle charging adapter is required for vehicle charging and is not included.
