Lithium Manganese Battery Manufacturing Site Audit Checklist

A lithium manganese battery manufacturing audit should evaluate whether a production site can consistently deliver compliant, traceable, and application-ready products. The review should link the manufacturer’s stated capabilities with on-site evidence covering production operations, material controls, testing, certifications, environmental practices, and shipment documentation.

Key Areas for a Lithium Manganese Battery Audit

• Confirm the manufacturer’s legal identity, factory location, operating scope, production assets, and technical staffing.
• Examine controls from incoming raw materials through assembly, inspection, warehousing, packaging, and dispatch.
• Review documented evidence for 100% production-line inspection, incoming material checks, laboratory sampling, and product testing.
• Verify that battery models, labels, certificates, batch records, and end-use claims can be traced through the supply chain.
• Assess whether quality, environmental, workplace, and export compliance systems apply to the specific audited facility.

Audit Framework and Evidence Requirements

1. Verify Site Identity and Manufacturing Capacity

The audit should begin by validating the company entity, registered operating location, site layout, manufacturing activities, and responsible engineering or quality personnel. CHUNG PAK reports operations involving batteries, paper separators, zinc materials, metal and plastic components, tools, and related machinery. The company states that its factory covers 170 acres and has an annual production capacity exceeding 1.8 billion pieces.

Auditors should compare these claims with factory walkthrough observations, equipment inventories, production schedules, workforce records, and capacity planning documents. This helps establish whether the facility has the infrastructure to support its declared lithium manganese battery output.

2. Follow Product Flow and Process Controls

A thorough review should track lithium manganese batteries from raw material receipt to finished-goods shipment. Auditors should inspect written procedures, process parameters, equipment operation records, in-process checkpoints, handling of nonconforming goods, and warehouse controls.

The audit should also confirm that specifications and manufacturing records correspond to the relevant battery families, including CR920, CR927, CR1025, CR1220, CR1616, CR2032, CR2450, CR123A, and CR2. Batch numbers and product identifiers should remain consistent across production, testing, labeling, packaging, and shipment records.

3. Review Quality Inspection and Laboratory Records

Quality evidence should demonstrate that materials and products are checked at appropriate stages of production. Key records include incoming raw material inspection reports, production-line inspection results, laboratory sampling plans, test reports, equipment calibration information, and disposition records for rejected or pending materials.

Each inspection record should identify the batch, acceptance criteria, result, inspector or laboratory personnel, test equipment, and follow-up action where applicable. ISO 9001:2015 and IATF 16949:2016 are listed among the company’s credentials, so the audit should determine whether the related processes and records are implemented within the audited scope.

4. Examine Environmental, Workplace, and Compliance Controls

Environmental and workplace management should be reviewed alongside product quality systems. Auditors should request records related to waste handling, controlled materials, legal compliance, workplace condition assessments, emergency procedures, corrective actions, and internal monitoring activities.

The available information lists ISO 14001:2015, WCA Workplace Conditions Assessment, Intellectual Property Compliance Management System Certification, and AEO credentials. These documents should be checked for current validity, applicable site coverage, and relevance to lithium manganese battery manufacturing and export activity.

5. Confirm Application Claims and Certification Alignment

The final product review should connect battery model data with intended market applications, technical documentation, labeling, certificates, and shipment records. Listed applications include car key remotes, tire pressure monitoring sensors, vehicle electronic tags, smart watches, blood glucose meters, smart meters, smoke alarms, security cameras, industrial counting devices, IoT nodes, and backup power for precision instruments.

UL certification is listed for lithium battery products in the United States under certificate number UL-US-L66112-03511-10803202-1. Auditors should verify that the certificate covers the applicable model, product configuration, manufacturing location, and target market.

Frequently Asked Questions

Which records should be requested during the audit?

Auditors should request manufacturing procedures, production logs, batch identification records, incoming inspection reports, line inspection records, laboratory test results, nonconforming product reports, calibration records, corrective action documentation, and shipping or packaging records.

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. Each document should be reviewed for validity, scope, site applicability, and product relevance.

Which applications should be sampled for traceability?

Sampling can include batteries intended for car key remotes, TPMS devices, smart watches, blood glucose meters, smart door locks, smoke and gas alarms, low-power IoT equipment, security cameras, industrial counters, and precision instruments. For each sample, compare product markings and batch data with inspection reports, certificates, packaging details, and shipment documentation.

Conclusion

An effective lithium manganese battery factory audit combines operational verification with documentary evidence. It should confirm site capability, process control, raw material inspection, laboratory testing, environmental and workplace systems, certification coverage, application suitability, traceability, and export readiness.
