III. Core Product Features

1. Patented Water-Saving & Reflux Design, Extending Battery Life

   
   

   The basket-type vent plug adopts a unique internal top cover structure that triggers a "wall-hitting reaction" of air flow, allowing water vapor to automatically condense into distilled water and flow back into the battery. Compared with standard vent plugs, the water loss rate is reduced by 60% (if the standard type loses 1kg of water, this product only loses 400g). This design can effectively delay the polarization speed of battery plates and significantly extend the overall service life of the battery. This structural technology was originally developed and customized for EnerSys (USA) and is currently patented (see attachment for reference).
2. Convenient Water Replenishment Design, Ensuring Battery Performance

   
   

   The top of the vent plug adopts a user-friendly water replenishment structure, which can timely replenish distilled water into the battery, avoiding battery performance degradation caused by water shortage and further ensuring the long-term stable operation of the battery.
3. Globally Selected Raw Materials, Strictly Controlling Source Quality

   
   

   Core raw materials are procured from the world's most suitable and high-quality suppliers. Each batch of raw materials undergoes full-index testing in Incoming Quality Control (IQC) to ensure stable basic quality of products from the source.
4. Full-Process Independent Production, Strengthening Quality Control

   
   

   All components of the product are manufactured independently by our company. Strict quality inspection standards are implemented in the pre-, mid-, and post-stages of component processing and finished product assembly to eliminate quality risks caused by component compatibility issues or assembly errors.
5. Customized Air Pressure Design, Adapting to Diverse Needs

   
   

   The gas opening pressure and closing pressure of the vent plug can be customized and adjusted according to the customer's actual application scenarios and needs, meeting the operating air pressure requirements of different types of batteries.
6. 100% Outgoing Inspection Mechanism, Ensuring Delivered Quality

   
   

   Before leaving the factory, each finished product must undergo functional testing with standard instruments in Outgoing Quality Control (OQC), verifying key indicators such as air tightness, reflux efficiency, and air pressure stability one by one to ensure that 100% of delivered products meet quality standards.

IV. Quality Control System

1. High-Quality Raw Material Procurement: Main raw materials are imported from Europe, America, Japan and other regions. All raw materials have passed strict verification by authoritative testing institutions to ensure that material performance meets standards.
2. Fully Independent Component Production: Components are manufactured on the company's internal production lines to avoid quality fluctuations caused by external OEM. Dedicated Quality Control (QC) personnel are assigned during the production process to conduct full-process inspection on component size, precision and material characteristics.
3. Customized Air Pressure Calibration: Relying on professional testing equipment, the gas opening and closing pressure can be accurately adjusted according to customer needs, with errors controlled within the industry-leading range.
4. Full-Functional Testing of Finished Products: Standardized testing instruments are used to conduct functional tests on each finished product, covering core dimensions such as water reflux efficiency, air pressure tightness and aging resistance, to ensure stable and reliable product performance.
