Fenix ARB-L18 is a high-current 18350 lithium-ion battery with a capacity of 1100 mAh with an advanced security system.

Reliability and performance

Thanks to the advanced design and multi-level protections, the manufacturer guarantees as many as 500 charging cycles while maintaining up to 75% of the capacity. This means that the cell can be discharged and charged every day for 1.5 years - which clearly emphasizes its quality and efficiency. Due to the lack of memory effect, Fenix batteries can be recharged at any time without negatively affecting their capacity and life. The steel body ensures high mechanical strength and minimizes the risk of a short circuit caused by a fall or impact. The battery uses pressurized vents responsible for expelling gas, which in the event of an incidental short-circuit may lead to distension or explosion.

Advanced security

The manufacturer has applied a multi-level protection system that maximizes the life of the battery and ensures the highest level of battery safety.

To maximize battery life, it is recommended to use a charger with a current of 1 A, maximum 2 A for charging. Maximum discharge current 10 A.
