Factory Audit Framework¶
For OEM and private-label buyers, a factory audit is the most reliable way to verify a battery manufacturer's production quality and claims. This framework outlines the key areas to evaluate.
Audit Checklist¶
1. Certifications¶
- IATF 16949 (automotive quality)
- ISO 9001 (quality management)
- ISO 45001 / OHSAS 18001 (occupational health & safety)
- Verify certificates are current and cover the relevant production lines.
2. Production Infrastructure¶
- Factory area and layout
- Number of automated production lines
- Annual and daily production capacity
- Whether capacity matches your volume requirements
3. Quality Control Process¶
- Incoming material inspection
- In-process testing
- Final product testing (CCA, capacity, RC)
- Batch traceability and documentation
4. Documentation Package¶
- Batch-specific test data
- Certificate of Analysis (COA) equivalent for batteries
- Dimensional and terminal verification reports
- Shipping and warranty documentation
Red Flags to Watch¶
- Certifications that cannot be independently verified
- No batch traceability or test documentation
- Unwillingness to share production process details
- Capacity claims that do not match physical infrastructure
