Keeppower 18650 4000 mAh battery

The Keeppower 18650 4000mAh Li-Ion battery (3.7V) with integrated protection circuit (PCB) offers maximum safety, reliability, and impressive energy density. With its high capacity of 4000mAh, this battery is the ideal choice for applications where long runtimes and maximum performance are required.
The integrated protection circuit reliably protects against short circuits, overcharging, and deep discharging, thereby extending the lifespan and significantly increasing operational safety. Thanks to the raised positive terminal (button top), the battery is compatible with many night vision devices and thermal imaging devices that rely on this design.
Please note that this battery is slightly larger than conventional 18650 cells due to the protection circuit (dimensions: 69.2 x 18.7 mm). Therefore, please check the dimensions of your device before purchasing.
To ensure that your Keeppower 18650 4000 mAh battery with protection circuit and raised positive terminal functions reliably, the following points should be checked:

Positive terminal type: Is the device or battery compartment designed for Button Top (raised positive terminal) or Flat Top (flat positive terminal)? Many devices, such as the Pard NV007, are designed for Flat Top batteries by default. If a device explicitly requires "Flat Top," a Button Top may be too tall.

Mechanical dimensions: The battery is slightly longer than standard 18650 cells due to the protection circuit and the raised positive terminal. Ensure that the battery compartment of your device can accommodate the length and diameter of 69.2 x 18.7 mm.
