Fenix Rechargeable Battery 18650 - 2600mAh

The ARB-L18-2600U battery offers dual charging options - via its built-in USB port or a charger. It has a protective circuit at the anode covered with a riveted steel hat. The full steel shell covering greatly reduces the risk of short - circuit from collisions or impacts. Key features include a Micro - USB charging port, a high 2600mAh capacity, protection circuitry against short - circuits, pressure vents to prevent explosions, a guaranteed 500 charge cycles before a 75% capacity drop due to memory effect, a 3.6V voltage, a recommended 1A charging current (max 2A), a 1A USB port charging current, a weight of 50g, dimensions of 70mm in length and 18.6mm in diameter, a 12 - month warranty from the purchase date, and an indicator light that turns red while charging and blue when fully charged.

Using this Fenix 18650 rechargeable battery is easy. You can charge it through the Micro - USB port or use a charger. When charging, keep an eye on the indicator light. It will be red when charging and turn blue once fully charged. For best results, use a 1A charging current, though the maximum is 2A (1A for the USB port). Make sure to handle the battery carefully to avoid collisions as, despite the protective steel shell, severe impacts could still cause issues. Don't overcharge the battery. After around 500 charge cycles, you might notice a 75% decrease in capacity due to memory effect. Store the battery in a cool, dry place. If you have any problems within 12 months from the purchase date, you're covered by the warranty.
