The Fenix ARB-L18-3500U is a 3500 mAh rechargeable 18650 Li-ion battery featuring a built-in micro-USB charging port. It can be charged directly without a separate battery charger.
An integrated protection circuit helps prevent overcharging and overheating. Low self-discharge and a lifespan of more than 500 charging cycles make it suitable for regular use. The maximum continuous discharge current is 8 A.
The battery is designed primarily for Fenix flashlights without built-in charging. It is also compatible with other devices that support button-top 18650 Li-ion batteries and accommodate a battery length of 70 mm.
Important: Check battery dimensions and terminal compatibility before purchasing. For flashlights with built-in charging, the manufacturer recommends batteries without an integrated USB charging port.
