XTAR Button-Top 18650 4000mAh (Set of 2)
PLEASE INQUIRE FOR CURRENT STOCK STATUS OR LEAD TIME PRIOR TO ORDERING
The XTAR 18650 4000mAh rechargeable battery is a high-capacity lithium-ion cell designed for extended runtime and consistent power delivery in demanding applications. With a true 4000mAh capacity and 10A continuous discharge capability, this battery provides an excellent balance of runtime and output for thermal optics, night vision devices, and other high-drain electronics.
This battery features a protected button top design and measures approximately 69.2mm in length, making it ideal for devices designed around longer 18650 cells with integrated protection circuitry. The built-in protection system safeguards against overcharge, over-discharge, overcurrent, and short circuit while maintaining reliable operation.
With over 600 charge cycles and stable voltage output under load, the XTAR 4000mAh battery is well suited for applications where both runtime and consistent performance are critical. Lower-quality batteries may experience voltage drop under load, which can negatively impact device operation and image processing in thermal optics.
Please Note: Battery length requirements can vary between thermal optics manufacturers (flat top vs. button top, etc.). Always measure your existing battery length to ensure reliable operation.
