TheFenix ARB-L18U 18650 3400 mAh 3.6V is a high-quality lithium-ion battery with the highest capacity available on the market and an innovative charging system via a micro-USB port.

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.

The battery uses an innovative charging system in the form of a built-in micro-USB port. This extremely practical and convenient solution allows charging the cell without the need for an additional charger. All you need to charge it is a standard micro-USB cable and a power source such as a power bank, laptop, desktop computer or car USB charger. The USB rechargeable battery not only saves money (on the purchase of a charger), it provides, above all, the convenience and mobility of charging.

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
• protection against overheating
• cathode with PTC protection (overload protection).

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

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

• headlamps
• hunting
• tactical
• everyday use
• bicycle
• camping.
