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.
