18650 battery 3.7 v 2600mAh Cell Production
To ensure good consistency, reliable performance, high automated production with strict quality controls are adopted. Integrated with PTC(Positive temperature Coefficient) and CID(current interrupt device), the 2600mAh 18650 battery can vent out gas in short-circuit conditions, ensuring ultimate safety and reliability.
Our price is competitive in the market due to large-scale cell production with high efficiency and good quality.
18650 battery 3.7v Advanatage
To avoid explosions and fires, the 18650 2600mAh battery cells are internally integrated with PTC(Positive temperature Coefficient) and CID(current interrupt device).Even under extreme conditions of short circuit, the rapid pressure increase will cause the gas vent out to avoid explosion accidents.
To ensure good reliability and stability, we adopt strict tolerances in voltage within 10mV, capacity within 5mAh, and internal resistance within 1mΩ, which provides the multiple cell assembly with good quality and great convenience.
After 1000 times cycle ,the 18650 2600mah battery can still retain 80% capacity. 18650 battery 2600mah with long shelf life of 2 years can provide stable power for various applications . Featuring low self-discharge rate as 2% per month, the 2600mah 18650 battery 3.7v rechargeable can maintain lowest capacity loss even after months of storage.
