The ARB - L18 - 2600U battery offers dual charging options: via its built - in USB port or a charger. It comes with a protective circuit on the anode, covered by a riveted steel hat. The full - coverage steel shell greatly reduces the risk of short - circuits from collisions or impacts. Key features include a Micro - USB charging port, a high 2600mAh capacity, protection circuitry to avoid short - circuits, pressure vents to prevent explosions, and a guaranteed 500 charge cycles before a 75% capacity drop due to memory effect. It has a 3.6V voltage, recommended 1A charging current (max 2A), and a 1A USB port charging current. Weighing 50g, it measures 70mm in length and 18.6mm in diameter. The 12 - month warranty starts from the purchase date. The battery's indicator light turns red while charging and blue when fully charged.
Using your Fenix 18650 rechargeable battery is easy. You can charge it either through the Micro - USB port or with a charger. Just connect it to a power source, and you'll see the red indicator light turn on, showing it's charging. Once it's done, the light will turn blue. When charging, it's best to use a 1A current as recommended, though it can handle up to 2A. The USB port charging current is fixed at 1A. Be careful not to drop or hit the battery hard, as even though it has a steel shell to reduce short - circuit risks, a strong impact could still cause problems. Also, remember that the battery has a limited number of charge cycles. You're guaranteed 500 cycles before a 75% capacity drop due to memory effect. To keep it in good shape, store it in a cool, dry place. And don't forget, you have a 12 - month warranty from the date of purchase, so if you run into any issues, you're covered.
