Battery Features:  

High capacity:

The main components use imported raw materials, so that the current international process formula makes the battery reach the same level as that of Japan, Europe and the United States.

Super high temperature performance:

our company's unique special production process original high temperature lithium thionyl chloride battery can work in the environment of 150 ℃.

Long life:

Long-term production inspection and customer use tracking, the life span can reach 10 to 15 years.

Small self-discharge:

After standing at 50℃ for 1 year, the self-discharge is less than 1%.


The quality management system is established in the factory according to the ISO9001 system, and strict quality control is implemented in all production. After strict inspection and matching of capacity, internal resistance, discharge platform, self-discharge, and special temperature treatment, the battery capacity is better than Domestic similar products.

Eight Advantages

The main raw materials are all imported from abroad, and the sealed lithium battery produced is novel in technology and has the following notable features andeight advantages:

1. Selection of raw materials (the main raw materials are imported from Japan, the United Kingdom and other places).

2. The raw materials are consistent and stable, and the utilization rate of active substances is particularly high.

3. Continuous production of pole pieces: The imported continuous production equipment ensures the consistency of pole pieces, thus laying a good foundation for the consistency of comprehensive performance of batch batteries.

4. Novel chemical formation method: The pole piece does not need to be formed, the battery is directly sealed and formed, and the amount of electrolyte added is accurate.

5. Good recovery performance: It can still discharge normally after 10 years of shelving.

6. 100% green battery: The battery does not contain heavy metal harmful chemical raw materials such as Hg, Pb and Cd.

7. Use and maintenance: Safety valve design and material selection are exquisite, safe and reliable, and can discharge quickly at high rate.

8. Trustworthy, all batteries produced have passed rigorous testing.

From the date of sale of the product, one-year free warranty, and after-sales service guarantee for life-long maintenance of the product, make you worry-free throughout the process.
