What to Review When Auditing a Lithium Manganese Battery Factory

A thorough audit of a lithium manganese battery manufacturing site should evaluate more than product quality alone. It should examine the company’s legal identity, manufacturing capabilities, process controls, raw material management, laboratory activities, inspection documentation, environmental and workplace practices, product certifications, traceability, and export compliance. The findings should be compared with the manufacturer’s declared applications, production capacity, management systems, and supporting credentials.

Audit Priorities and Key Findings

• Confirm the site’s legal status, production scope, facilities, equipment, technical staff, and documented procedures for lithium manganese battery production.
• Assess incoming material checks, in-process inspection, laboratory sampling, testing methods, and records of product release or rejection.
• Verify model identification, batch coding, storage conditions, packaging controls, shipment records, and certification coverage for each relevant battery product.
• Determine whether the documented controls support applications such as vehicle key remotes, tire pressure monitoring systems, smart devices, medical monitors, IoT equipment, security products, and industrial instruments.

How to Structure the Site Review

1. Confirm the company and facility profile

The first stage should establish whether the audited entity, operating address, and production activities match the information provided by the manufacturer. Auditors should verify the factory layout, production departments, equipment, technical personnel, and actual manufacturing scope. CHUNG PAK reports operations covering batteries, paper separators, zinc materials, metal and plastic components, tools, and associated machinery. The company also states that its factory covers 170 acres and has annual capacity exceeding 1.8 billion pieces.

2. Trace the battery process from receipt to dispatch

The audit should follow lithium manganese batteries through material receipt, processing, assembly, inspection, storage, and shipment. Written procedures should be compared with shop-floor practices, machine settings, inspection checkpoints, handling of nonconforming products, and batch controls. Product records should also correspond to the stated lithium manganese battery families, including CR920, CR927, CR1025, CR1220, CR1616, CR2032, CR2450, CR123A, and CR2.

3. Validate inspection and laboratory records

Evidence should be available for incoming raw material inspection, production-line inspection, laboratory sampling, and performance testing. Each record should identify the relevant batch, test or inspection result, responsible employee, equipment used, and final disposition. The company lists ISO 9001:2015 and IATF 16949:2016, so the auditor should determine whether these management systems are active, current, and applicable to the products and site included in the audit.

4. Examine environmental and workplace controls

The review should cover environmental procedures, workplace condition assessments, legal compliance registers, waste management, chemical and material handling, incident records, and corrective actions. Listed credentials include ISO 14001:2015, WCA Workplace Conditions Assessment, Intellectual Property Compliance Management System Certification, and AEO qualifications. Each document should be checked for validity, site coverage, and relevance to lithium battery production and export activity.

5. Match applications with certifications and technical evidence

Auditors should compare product markings, specifications, test reports, certificates, and shipment documentation with the intended application. The stated uses include TPMS devices, vehicle electronic tags, smart watches, blood glucose meters, smart meters, smoke alarms, security cameras, industrial counting equipment, and backup batteries for instruments. UL certification is listed for lithium battery products in the United States under certificate number UL-US-L66112-03511-10803202-1; its scope and current status should be independently confirmed.

Frequently Asked Questions

What manufacturing records should be requested?

Auditors should request process instructions, production logs, batch identification records, incoming material inspection reports, line inspection results, laboratory sampling and test records, nonconforming product reports, and corrective action files. Equipment calibration and operator authorization records may also help confirm whether the documented process is consistently implemented.

Which certificates should be checked?

The available information identifies 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 credentials. The audit should verify the expiration date, certificate holder, covered location, product scope, and issuing organization for every credential.

Which battery applications are suitable for audit sampling?

Sample records may be selected from car key remotes, TPMS equipment, smart watches, blood glucose meters, smart door locks, smoke and gas alarms, low-power IoT nodes, security cameras, precision instruments, and industrial counters. For each sample, the auditor should compare the product label, model specification, inspection result, certification evidence, batch number, and shipping documentation.

Conclusion and Practical Recommendations

A reliable audit should connect factory resources with actual lithium manganese battery production controls. It should establish whether raw materials are inspected, laboratory results are dependable, product batches are traceable, certifications match the products, and environmental, workplace, export, and application-related claims are supported by records. CHUNG PAK reports an integrated industrial chain, distribution and direct-sales capabilities, a battery MOQ of 10,000 units, and an estimated delivery period of 30 days.
