Fenix ARB-L18 is a high-current 18350 lithium-ion battery with a capacity of 1100 mAh and an advanced protection system. Due to its specific design ("flat plus"), the battery is only compatible with Fenix GL19R and Fenix TK05R flashlights.

Reliability and performance

Thanks to its advanced design and multi-level protection, the manufacturer guarantees up to 500 charging cycles with up to 75% capacity. This means that the cell can be discharged and recharged daily over a period of 1.5 years - which clearly emphasizes its quality and performance. Due to the lack of memory effect, Fenix batteries can be recharged at any time without adversely affecting their capacity and service life. The steel body provides high mechanical strength and minimizes the risk of short-circuiting caused by a fall or impact. The battery uses pressurized vents responsible for expelling gas, which can lead to a bloat or explosion during an incidental short circuit.

Advanced safety features

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

Safety systems:

• Over-discharge protection during use,
• Protection against overcharging during the charging process,
• circuit protection against short circuits,
• overheating protection.

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