In Stock ✓ Product Code (SKU): ARB-L18-4000
- Category: Fenix Accessories
The Fenix ARB-L18-4000 is a high-capacity 4000mAh 18650 rechargeable battery for users who want extended runtime from a compatible non-USB Fenix cell. Its 7A maximum output supports demanding lights, while the conventional battery shape avoids the extra length added by an integrated charging port.
High Capacity For Demanding Use
The 4000mAh capacity can extend the time between battery changes or charging sessions in compatible equipment. It is particularly useful for professional work, cycling and outdoor trips where dependable lighting may be required for several hours.
Stable Output And Thermal Performance
A maximum 7A output supports high-performance lighting, while multiple protection circuits help guard against overcharging, over-discharging, short circuits and overheating. Pressure-relief vents provide an additional safeguard.
Charging And Compatibility
The ARB-L18-4000 has no built-in USB port and must be charged in a compatible external charger or supported Fenix light. It is a protected button-top battery, so confirm compatibility with the exact model before purchase.
