Fenix ARB-L21B rechargeable battery in a durable steel housing
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 swell or explosion during an incidental short circuit.
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, a current of 1.2 A is recommended for charging, with a maximum of 3 A.
