Fenix ARB-L21 rechargeable battery (21700 6000 mAh 3.6 V)

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.
