Actual capacity of 3500 mAh for long-lasting power

The high capacity of 3500 mAh provides enough power for long-term operation of more demanding devices. The battery is suitable for high-performance flashlights, headlamps, tactical and outdoor gear, and other electronics that use 18650 cells.

Reliable operation across a wide temperature range

The battery is designed for operation at temperatures ranging from –20 to +60 °C, making it suitable for use in both cold and warm environments. It is well-suited for outdoor devices such as trail cameras, flashlights, and headlamps, as well as other electronics that use 18650 cells. Its robust construction provides the necessary performance even under more demanding operating conditions. Compliance with CE, RoHS, and UN38.3 standards further underscores the emphasis on safety, quality, and reliable transport of the battery.

More than 800 charge cycles

The high-quality design enables a service life exceeding 800 charge cycles, which is approximately 60% more than standard cells with a service life of around 500 cycles. When charged and stored properly, the battery offers reliable performance over a long period of time.

Stable performance with lower energy losses

Low internal resistance of approximately 45 mΩ enables more efficient energy transfer and helps maintain stable battery performance even under higher loads. Compared to standard cells with higher internal resistance, less energy is converted into unwanted heat, thereby reducing heating and energy loss. A maximum continuous discharge current of 10 A allows the battery to power even more powerful flashlights, headlamps, and other electronic devices with higher power demands. A stable discharge curve contributes to reliable device operation and helps make better use of the battery’s available capacity. The result is safe and consistent performance during both everyday and more demanding use.

Multiple layers of protection for safe operation

Integrated protective features safeguard the battery against overcharging, over-discharging, and short circuits. Reliable construction and thorough testing contribute to safe operation, a longer service life, and protection for the powered device.
