Fenix ARB-L18 18650 4000 mAh 3.6 V is a high-quality lithium-ion battery with the highest capacity available on the market, designed for hunting and tactical flashlights and devices with high power consumption.

Fenix USB ARB-L18 battery (18650 4000 mAh 3.6 V) - capacious and practical.

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 every day 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.

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:

• protection against over-discharge during use,
• protection against overcharging during the charging process,
• circuit protection against short circuits,
• overheating protection,
• cathode with PTC protection (overload protection).

To maximize the life of the battery, a current of up to 4 A is recommended for charging.

The use of Fenix 18650 batteries guarantees maximum light performance and is recommended for use in flashlights:

• frontal,
• hunting,
• tactical,
• everyday use,
• bicycle,
• camping.
