Fenix ARB-L37 rechargeable battery (12000 mAh 3.6 V)

Fenix ARB-L37 3.6 V is an original lithium-ion battery with a capacity of 12000 mAh dedicated to the flashlight Fenix LR40R.

Thanks to its advanced design and multi-level protection, the manufacturer guarantees as many as 500 charging cycles with up to 75% capacity retention.

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.

Steel body provides high mechanical strength and minimizes the risk of short-circuiting due to a fall or impact.

The battery uses pressurized vents that are responsible for expelling gas, which can lead to a bloat or explosion during an incidental short circuit.

The manufacturer has used a multi-level security system that maximizes the life and provides the highest level of safety for the battery pack.

Security 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 current of 1 A for charging, a maximum of 5 A.
