The OEM battery development process
OEM development is a gated process. Understanding the stages tells you where to be involved and where to insist on sign-off.
The seven stages
- Consultation
- Specification
- Design & branding
- Sampling
- Mass production
- Quality inspection
- Logistics & shipping
Where buyers should be involved
- Specification — sign off every parameter
- Sampling — test before approving
- Quality inspection — agree the acceptance criteria
- Shipment — confirm documentation
Why gates matter
Each gate is a decision point. Skipping a gate is how a specification drifts and a repeat order comes back different.
Stage-by-stage: who does what
| Stage | Manufacturer delivers | Buyer action |
|---|---|---|
| 1. Consultation | Feasibility view on the requested specification | Confirm vehicle, market and volume intent |
| 2. Specification | Written spec sheet with every parameter | Sign every line, including the CCA test basis |
| 3. Design & branding | Label and packaging artwork | Approve artwork and documentation |
| 4. Sampling | Pre-production sample from a production-equivalent line | Test before approving; record results |
| 5. Mass production | Scheduled production with in-process control | Confirm the schedule and any change freeze |
| 6. Quality inspection | Inspection and test data | Agree acceptance criteria before release |
| 7. Shipping | Export packaging and documents | Confirm documents before shipment |

Where the buyer must sign off
Four gates need a buyer signature, not just a manufacturer confirmation:
- Specification — sign every parameter, including the CCA test basis.
- Sample — test the pre-production sample before approval.
- Quality standard — agree acceptance criteria before mass production.
- Shipment — confirm the documents before release.
Skip one gate and the next order can drift from the approved sample. Keep the sign-off sequence tied to the OEM program phases so both sides know where approval is required.
