Fenix USB Battery ARB-L18U (18650 4000 mAh 3.6 V) - practical and capacious.
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 battery uses an innovative charging system in the form of a built-in USB-C 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 protection system, which maximizes the life and ensures the highest level of safety of the battery.
To maximize the life of the battery, a current of 0.8 A is recommended for charging, with a maximum of 4 A.
