The Fenix ARB-L18-3400U Rechargeable Battery is a high-performance power source designed for Fenix flashlights and other 18650-compatible devices.
With a large capacity of 3400mAh, this battery provides longer runtimes and reliable power output. It features an integrated protection circuit in the positive terminal, which prevents overcharging, over-discharging, short circuits, and overheating.
A key advantage of this battery is its built-in micro-USB charging port, allowing convenient charging without the need for an external charger. Simply connect a micro-USB cable (not included) to recharge the battery directly. Alternatively, it can still be charged using a traditional Li-ion battery charger.
To enhance safety, the steel shell protection reduces the risk of impact damage and short circuits, while the pressure relief vents help prevent battery expansion or explosion in case of internal malfunctions.
With a lifespan of up to 500 charge cycles, the ARB-L18-3400U ensures long-term performance and efficiency for your rechargeable devices.
