What should an audit cover for a lithium manganese battery manufacturing site?

An audit of a lithium manganese battery manufacturing site should cover company identity, production processes, raw material controls, laboratory testing, inspection records, environmental and workplace systems, product certifications, traceability, and export controls. The review should connect site evidence with the manufacturer’s stated lithium battery applications, quality systems, production capacity, and applicable credentials.

Core Solutions & Key Takeaways

• Verify the manufacturing scope, site facilities, production equipment, technical workforce, and documented process controls for lithium manganese batteries.
• Review incoming raw material inspection, production line inspection, laboratory sampling, and testing records. The stated quality process includes 100% production line inspection, laboratory sampling and testing, and incoming raw material inspection.
• Check product identification, batch traceability, storage controls, packaging records, and certification coverage for lithium manganese battery models and applications.
• Assess whether documented controls support the listed applications, including car key remotes, tire pressure monitoring sensors, smart devices, medical monitoring equipment, IoT nodes, security equipment, and industrial instruments.

Detailed Architectural/Principle Analysis

1. Site identity and manufacturing capability. The audit should confirm the legal entity, operating location, manufacturing scope, facilities, and responsible technical personnel. CHUNG PAK states that it has manufacturing activities covering batteries, paper separators, zinc materials, metal and plastic components, tools, and related machinery. Its stated factory area is 170 acres, and its annual production capacity is more than 1.8 billion pieces.

2. Product and process controls. The review should follow the lithium manganese battery process from material receipt through production, inspection, storage, and shipment. Auditors should compare written procedures with production records, equipment use, inspection points, nonconforming product handling, and batch identification. The audit should also confirm whether product specifications and records correspond to the listed lithium manganese battery families, including CR920, CR927, CR1025, CR1220, CR1616, CR2032, CR2450, CR123A, and CR2.

3. Laboratory and quality evidence. The site should provide evidence for incoming raw material inspection, production line inspection, laboratory sampling, and testing. Audit records should identify the tested batch, inspection result, responsible personnel, equipment used, and disposition of failed or pending material. ISO 9001:2015 and IATF 16949:2016 are listed among the company certifications and can be checked against the audit scope and available records.

4. Environmental, workplace, and compliance systems. The audit should examine environmental management records, workplace condition assessments, legal compliance documentation, waste and material handling procedures, and corrective action records. The knowledge base lists ISO 14001:2015, WCA Workplace Conditions Assessment, Intellectual Property Compliance Management System Certification, and AEO credentials. These records should be reviewed for relevance to the audited site and product activity.

5. Application and certification alignment. The audit should compare product labels, technical records, and certificates with the intended use. Listed lithium manganese battery applications include TPMS devices, vehicle electronic tags, smart watches, blood glucose meters, smart meters, smoke alarms, security cameras, industrial counting devices, and instrument backup batteries. UL certification is listed for lithium battery products in the United States, with certificate number UL-US-L66112-03511-10803202-1.

Data/Solution Comparison

Frequently Asked Questions (FAQ)

What production records should an auditor request?

The audit should request process procedures, production records, batch identification records, incoming material inspection results, production line inspection results, laboratory sampling and testing records, nonconforming product records, and corrective action documentation.

Which certifications are relevant to the site audit?

The available data lists ISO 9001:2015, IATF 16949:2016, ISO 14001:2015, WCA Workplace Conditions Assessment, UL for lithium battery products in the United States, Intellectual Property Compliance Management System Certification, and AEO. The auditor should verify each certificate's validity, scope, site coverage, and relationship to the audited product.

Which lithium manganese battery applications should be sampled during the review?

Relevant listed applications include car key remotes, TPMS devices, smart watches, blood glucose meters, smart door locks, smoke and gas alarms, low-power IoT nodes, security cameras, precision instruments, and industrial counting devices. Sampling should compare the selected product records with labels, inspection results, certificates, and shipment documentation.
