Fenix ARB-L21P battery (4000 mAh 3.6 V)

Fenix ARB-L21-4000 MAH is a high-quality 21700 lithium-ion battery with a standard 4000 mAh capacity for hunting and tactical flashlights and devices with high current consumption.

Thanks to the advanced design and multi -level security, the manufacturer guarantees up to 500 charging cycles with up to 75% capacity. This means that the cell can be discharged and charged daily during the 1.5-year period-what clearly emphasizes its quality and performance.

The Arb-L21P battery is characterized by a high discharge current to 10 A (impulse discharge current to 18 A), high energy and voltage density, so it can be used to supply flashlights with increased energy demand.

Due to the lack of memory effect , Fenix batteries can be recharged at any time, without a negative impact on their capacity and service life.

The steel body provides high mechanical strength and minimizes the risk of short circuit caused by falling or impact. The battery uses pressure ventilation holes , responsible for gas excretion, which during an incidental short circuit can lead to disgust or explosion.

The manufacturer used the multi -level security system , which maximally extends the service life and provides the highest level of battery safety.

Safety systems:

• Protection against excessive discharge during use
• Protection against reloading during the charging process
• Protection of the circuit against short circuits
• Protection against overheating
• cathode with PTC protection (anti -reactive protection). Charging It is recommended to use 1 a , maximum 4 a.
