Fenix ARB-L21-6000 is a 21700 type high-current lithium-ion battery with an impressive capacity of 6000 mAh equipped with an advanced protection system.

Fenix ARB-L21-6000 battery - features

• Cell type: lithium-ion 21700 battery with a capacity of 6000 mAh.
• High capacity: the most capacious flashlight cell, providing long operation and stable current output.
• Longevity: 500 charging cycles with up to 75% of the original capacity.
• No memory effect: can be recharged at any time without affecting capacity and life.
• Steel body: provides mechanical strength and minimizes the risk of short-circuiting in drops.
• Pressure vents: dissipates gas in the event of a short circuit, preventing bloating or explosion.
• Advanced safety systems.

Reliability and performance

The ARB-L21-6000 is currently the highest-capacity flashlight power cell, providing significantly longer operation and consistent current output.

Thanks to its advanced design and multi-level protection systems, 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 negative impact on 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.

Fenix ARB-L21-6000 battery - 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:

• 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, it is recommended to use a charger with a current of 1.2 A for charging, with a maximum of 4.2 A. Maximum discharge current of 10 A.
