Quality Assurance of Flooded Tubular Battery

We pursued in  continueous advanced and that is the meaning of life. Improving our product quality bring an enhancement to our brand image. The new quality control   concept fueled SUNBRIGHT with deeper connotation. Working strict follow to   the ISO9001 quality control system, we do:

1. Equipment control: We adopt the entire computer automatic control.(Density   testing, adding acid, charging, etc.)
2. Raw material control: Any raw material will be forbidden used in the production   if they didn't pass the testing by laboratory strictly.

3. Production process control: The semi-finished products must pass several   inspections in the production line.

4. Finished products control: The finished battery must be tested 100% by four   function testing machine and pass the inner resistance testing, density   testing, 3-5 discharge performance testing etc. before packaging.

5. Shipment control: The goods can't be sold unless their appearance and   performance are tested 100% by the professional inspector.
