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.
