Product Description
Overview & Value Proposition
XTAR 18650 3.6V 4000mAh Ultra-High Capacity Rechargeable Li-ion Battery
Engineered for next-generation portable devices, tactical equipment, and high-drain lighting, this cell breaks through conventional capacity limits to deliver true 4000mAh (14.4Wh) in a compact 18650 form factor. Featuring a 10A continuous high discharge rate and an integrated intelligent protective circuit board (PCB), it provides exceptional safety, ultra-long runtime (+15%), and superior consistency for global OEM/ODM manufacturers.

Why Wholesale & Distribute XTAR 18650 4000mAh?
- Compared to standard 3500mAh cells, our 4000mAh chemistry delivers an extra +500mAh capacity, extending device runtime significantly (e.g., adding 15 to 50 minutes on high-lumen tactical & diving lights).
- Optimized low internal resistance ensures a stable discharge curve even under high 10A draw, avoiding thermal throttling and premature shut-off in sensitive electronics.
- Equipped with a micro-circuit protection board engineered for less heat loss and enhanced lifecycle preservation.
- Designed for heavy-duty industrial use, maintaining high capacity retention even after 600 full discharge/charge cycles, drastically reducing replacement and maintenance costs for your end-users.
