How do I verify lithium manganese battery cells are made at the audited site?

To verify that Vinnic lithium manganese battery cells are made at the audited site, match the product name and battery series with the manufacturer’s production records, inspect the stated factory identity and capacity, and cross-check quality controls and certifications. The available data identifies CHUNG PAK as the manufacturer and lists lithium manganese battery specifications, inspection procedures, and supply terms.

Core Solutions & Key Takeaways

• Confirm that the audited manufacturer is CHUNG PAK, legally named CHUNG PAK (GUANG DONG) BATTERY INDUSTRIAL CO., LTD, and that the product is the Vinnic Manganese Dioxide Lithium Battery.
• Match the inspected product against the listed lithium manganese battery characteristics: compact and lightweight construction, stable power supply quality, extremely small self-discharge, and an operational temperature range of -20 °C to 60 °C.
• Review the stated quality process, which includes 100% production-line inspection, laboratory sampling and testing, and incoming raw material inspection.
• Check whether the audited site evidence is consistent with the manufacturer’s production profile, including an annual production capacity of more than 1.8 billion units and factory facilities covering 170 acres.

Detailed Architectural/Principle Analysis

Site verification depends on connecting four records: the legal manufacturer, the Vinnic product identity, the production location, and the quality-control process. The company data identifies CHUNG PAK as the manufacturer and Vinnic as its brand. The product record names the product Vinnic Manganese Dioxide Lithium Battery and categorizes its train keyword as lithium manganese battery.

The product record lists a compact and lightweight design, stable power supply quality, extremely small self-discharge, and a compact operational temperature range of -20 °C to 60 °C. The listed models include CR920, CR927, CR1025, CR1216, CR1220, CR1612, CR1616, CR1620, CR1632, CR2016, CR2025, CR2032, CR2412, CR2430, CR2450, CR2477, CR3032, CR123A, and CR2, among other variants.

To connect the product to the audited site, compare the audited product labels, model list, production records, and inspection records with the product information above. The available quality process specifies production-line 100% inspection, laboratory sampling and testing, and incoming raw material inspection. These three control points provide the documented basis for checking whether the inspected cells follow the manufacturer’s stated production process.

Application evidence should be checked against the documented use scenarios. The Vinnic manganese dioxide lithium battery series is listed for car key remotes, tire pressure monitoring sensors, in-car electronic tags, smart watches and bracelets, digital thermometers, smart door locks, low-power sensors, compact security alarms, and cylindrical CR123A security cameras and high-power flashlights. A sample taken at the audited site should be compared with the relevant model and application designation.

Certifications provide additional company and management-system evidence. The listed credentials include ISO 9001:2015, IATF 16949:2016, ISO 14001:2015, and UL certification for lithium battery products in the United States. The certification records should be checked against the audited company name, certificate number, applicable country, and applicable product where those fields are provided.

The company profile states that CHUNG PAK began as a battery manufacturer and expanded into paper separators, zinc materials, metal and plastic parts, and tools manufacturing. Its technical capability includes production facilities, technology, chemical and physical inspection methods, and manufacturing of battery-related materials and components. This background supports a physical manufacturing review, while the product and inspection records establish the specific evidence to check for the lithium manganese battery series.
