OEM & Private Label Batteries
How to launch your own battery brand with a supply partner: OEM vs ODM, branding, specs, samples, packaging, and the responsibilities on each side.
OEM vs ODM
OEM (Original Equipment Manufacturing): you provide the design or detailed specification; the manufacturer builds to your spec and puts your brand on it. Best when you know exactly what you want.
ODM (Original Design Manufacturing): the supply partner provides proven designs; you customize branding, and optionally adjust specs, features, or packaging. Faster to market when you trust the partner’s engineering.
Branding and labeling
- Your logo, brand name, and model naming on the battery case and packaging.
- Label content must be accurate: nominal voltage, capacity, energy (Wh), chemistry, and required safety markings for your market.
- Decide who designs the artwork and who approves the final proof — get this in writing before production.
Technical specifications
Define the spec sheet together: cell type, series/parallel configuration, BMS parameters (continuous/peak current, protections, communication), charge parameters, operating temperature range, enclosure (IP rating if relevant), terminals, and dimensions. Ambiguity here becomes disputes later — be precise.
Samples and approval
Always approve a pre-production sample before bulk manufacturing. Test it against your spec sheet: capacity, BMS cutoffs, communication (if any), labeling, and packaging. The approved sample becomes the reference for incoming quality checks.
Packaging
Batteries ship as dangerous goods — packaging must meet UN38.3 transport requirements, not just look good. Discuss retail packaging vs bulk packaging, palletization, and labeling for your logistics chain.
Certifications: who is responsible
Clarify early which certifications your market requires (CE, UL, UN38.3, etc.) and who obtains and pays for them. A certificate belongs to a specific product configuration — changing cells, BMS, or enclosure may invalidate it. Get this agreed in writing.
Quality control
- Agree on inspection criteria: what is checked, how, and to what standard (AQL levels if applicable).
- Decide whether you inspect at the factory, use a third party, or inspect on arrival.
- Keep records: batch numbers, test reports, and the approved sample for comparison.
After-sales responsibility
Define the warranty terms your brand offers, and separately what the supply partner covers and for how long. Agree on the claims process: who diagnoses, who pays for return shipping, and how replacements are handled. Your customers will hold you responsible — make sure your partner arrangement supports that.
