Description
Product Description:
The Fenix ARB-L18-1600 is a premium-grade 18350 rechargeable lithium-ion battery engineered for high performance, safety, and reliability. With a generous 1600mAh capacity and a powerful 7A maximum output current, this battery delivers long-lasting, stable energy for high-drain devices such as high-lumen tactical flashlights, headlamps, and outdoor gear.
Built to Fenix's rigorous standards, the ARB-L18-1600 features an advanced built-in protection circuit integrated into the positive terminal. This provides battery quadruple protection against over-charging, over-discharging, short circuits, and overheating. Additionally, the cell offers triple-layer protection with a safety pressure relief valve, separator micro-porous protection, and PTC cathode blocking.
The battery is encased in a full metal shell with a riveted steel casing, effectively preventing short circuits caused by collisions or impacts. A built-in safety vent rapidly exhausts internal gases in extreme conditions, preventing battery swelling or explosion. With a 500-cycle lifespan and a 12-month official warranty, it is a trustworthy investment for your high-performance gear.

Security
Been using it daily for the last week. No issues with charging or discharging. It's a reliable battery from a trusted brand.
Works perfectly with my Fenix HL60R headlamp. Long runtime and I feel safe knowing it has a protection circuit. A must-have for night hiking.
The battery itself is great, but the retail packaging was a bit flimsy when it arrived. Fenix should improve the box for single cells.
Does exactly what it's supposed to do. Good build quality and the wrapper is durable. Would buy again.
I keep this as a spare for my camping trips. 500 cycles is a solid lifespan. It's nice to have a protected cell that I don't have to worry about over-discharging.
