Lithium Manganese Battery Factory Audit Checklist: Scope, Quality, and Compliance

A lithium manganese battery manufacturing audit should provide a complete view of how the site operates, controls quality, manages materials, and supports product compliance. The assessment should connect physical factory evidence with the manufacturer's declared production capacity, battery applications, quality systems, certifications, traceability practices, and export documentation.

Essential Areas for a Lithium Manganese Battery Audit

An effective audit goes beyond reviewing certificates. It should test whether documented procedures are actively followed from raw-material receipt through finished-goods shipment.

• Confirm the company's legal identity, manufacturing address, facility scope, production assets, and qualified technical personnel.
• Examine controls for incoming materials, in-process inspection, laboratory sampling, final verification, and nonconforming products.
• Review batch coding, product labels, warehouse conditions, packaging records, and shipment traceability.
• Verify that battery models, certifications, and manufacturing controls align with their stated end-use markets and applications.

Factory Capability and Operating Scope

Site identity, facilities, and production resources

The audit should first establish which legal entity operates the plant and which activities are performed at the audited location. CHUNG PAK states that its manufacturing operations include batteries, paper separators, zinc materials, metal and plastic components, tooling, and related machinery. The company reports a factory area of 170 acres and annual production capacity exceeding 1.8 billion pieces.

Auditors should validate these claims through site tours, equipment inventories, production planning records, workforce information, maintenance documentation, and manufacturing output data. The review should also identify the personnel responsible for engineering, quality assurance, laboratory operations, and regulatory compliance.

Production Process and Quality Control Review

Material-to-shipment process verification

The audit should trace lithium manganese batteries through each operational stage: material receipt, storage, production, inspection, finished-goods handling, packaging, and dispatch. Written work instructions should be compared with actual line practices, equipment settings, inspection stations, production records, and controls for rejected material.

Product specifications and traceability records should correspond with the battery models manufactured at the site. Relevant lithium manganese battery families may include CR920, CR927, CR1025, CR1220, CR1616, CR2032, CR2450, CR123A, and CR2.

Inspection and laboratory evidence

Auditors should request evidence of incoming raw material inspection, 100% production line inspection, laboratory sampling, and testing. Each record should clearly identify the applicable batch, test method, inspection outcome, operator or inspector, equipment used, and disposition decision for failed or pending material.

Quality-system evidence should also be reviewed against the stated certifications, including ISO 9001:2015 and IATF 16949:2016. The audit should determine whether the certificate scope, actual site processes, and available quality records are consistent.

Compliance, Environmental, and Workplace Controls

Environmental and workplace management should form a separate part of the audit. Key evidence includes environmental monitoring records, waste handling procedures, chemical and material controls, workplace condition assessments, legal compliance documentation, incident records, and corrective action tracking.

The available credentials include ISO 14001:2015, WCA Workplace Conditions Assessment, Intellectual Property Compliance Management System Certification, and AEO status. Auditors should confirm that each credential applies to the audited factory, remains valid, and is relevant to the products and activities under review.

Certification, Applications, and Traceability Alignment

A strong audit links every battery model to its intended use, quality evidence, labeling, and certification coverage. Product labels, technical specifications, batch records, certificates, and shipping documents should provide a consistent record of the product's identity and destination.

Listed applications for lithium manganese batteries include car key remotes, tire pressure monitoring systems, vehicle electronic tags, smart watches, blood glucose meters, smart meters, smoke alarms, security cameras, low-power IoT nodes, industrial counting devices, and backup power for precision instruments. Sampling should test whether these application claims are supported by the relevant model specifications and compliance records.

UL certification is listed for lithium battery products in the United States under certificate number UL-US-L66112-03511-10803202-1. The audit should verify the certificate's current validity, covered product range, site relationship, and supporting technical documentation.

Audit Evidence Summary

Frequently Asked Questions

Which records should be requested during the audit?

Auditors should collect process flow documents, operating procedures, production records, batch identification logs, material inspection reports, in-process inspection results, laboratory test reports, nonconforming product records, and corrective action evidence.

What certifications should be checked?

Relevant listed credentials include ISO 9001:2015, IATF 16949:2016, ISO 14001:2015, WCA Workplace Conditions Assessment, UL certification for lithium battery products in the United States, Intellectual Property Compliance Management System Certification, and AEO. Every certificate should be checked for validity, scope, facility coverage, and product relevance.

Which applications should be included in product sampling?

Product sampling can cover car remote controls, TPMS devices, smart watches, glucose meters, smart locks, smoke and gas alarms, IoT equipment, security cameras, industrial counters, and precision instruments. For each sample, auditors should compare product markings, inspection data, technical files, certificates, and shipment documents.

Conclusion

A complete lithium manganese battery site audit should combine manufacturing capability, process discipline, material controls, laboratory evidence, environmental and workplace management, certification review, application validation, traceability, and export readiness.
