- long life: up to 500 charging cycles with approximately 75% capacity retention;
- steel body - high resistancemechanical resistance and less risk of short circuit after a fall;
- pressurized vents to vent gases in emergency situations;
- multi-level protection: over-discharge, over-charging, short-circuit, overheating; PTC cathode (overload protection);
- recommended charging: 1 A charger (max. 5 A) for extended life.
Reliability and performance
The ARB-L21-5000 is currently the highest capacity flashlight power cell, providing significantly longer operation and consistent current output.
Thanks to the 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 emphatically 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-L21-5000 V.2 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
- protection against overheating
- 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 A for charging, with a maximum of 5 A. Maximum discharge current of 7.5 A.
