Private label, from 200 pieces
Your logo printed on the battery label, your artwork on the box, your manual inside. We handle the die-line, the printing and the barcode.
- Label, box, blister and manual design
- Barcodes and retail-ready packing
OEM & ODM mobile phone battery manufacturing
Your brand, our factory. We build private-label phone batteries from 200 pieces: custom capacity, custom connector, custom label and retail packaging, developed from your sample or your drawing.
What we customise
Four things you control on every order
We already run our own brand, J-Rong. Building a private label for you uses exactly the same line, the same cells and the same testing — just your name on the artwork.
Choose your capacity tier
Sell two price points from the same market: a standard original-capacity build and a high-capacity build, both honestly labelled.
- Original capacity or high capacity
- 0-cycle brand-new cells on request
Custom connector and flex
Match the connector, flex cable and positioning of any handset model, including diagnostic-compatible IC versions for the iPhone range.
- Model-specific flex and connector
- Diagnostic IC option available
From your sample or your drawing
Send a sample, a part number or a full drawing set. Our engineers confirm the specification, produce a prototype and approve it with you before mass production.
- Prototype before mass production
- Spec sheet issued for every custom line
How we work
Six steps from your first message to your first shipment
1
Enquiry
Send models, target capacity and quantity. We reply with an indicative FOB price and confirm what can be customised.
2
Specification
We issue a written spec sheet — capacity, voltage, connector, label artwork, packaging and MOQ for your custom line.
3
Sample
We build samples to that spec. Custom samples for qualified buyers are free; you cover the courier. Lead time is typically 7 days.
4
Approval
You test the sample for capacity, fit and finish. We adjust until you sign it off.
5
Mass production
Production runs on our automated lines with in-process monitoring. Every unit is inspected before packing.
6
Shipment
Export cartons, MSDS and certificate documents, then booking from Shenzhen or Guangzhou on your chosen Incoterm.
Customisation options

Answers
OEM & ODM questions
The four questions buyers ask before starting a private-label project.
Can you print our own brand and packaging?
Yes — that is most of what we do. Full OEM and ODM support covers your logo on the battery label, custom capacity, custom connector and flex, retail blister or box packaging, instruction manuals and barcodes. Customisation starts from 200 pieces, and free samples of your custom design are available for qualified buyers.
Do you provide samples?
Yes. Free samples are available for qualified buyers; you only cover the courier cost. We ship samples by DHL, FedEx, UPS, TNT or EMS, and sample lead time is typically 3–7 days. For custom-branded samples the lead time is confirmed with your artwork.
What warranty do you offer?
At least 12 months from the date of shipment on all batteries. If a quality issue appears, we send replacements. After-sales requests are answered within 48 hours, and long-term partners can agree a customised warranty period.
How do you control quality?
Every unit is inspected — 100% visual and function inspection before packing. Incoming cells are screened on arrival, production is monitored in line, and finished goods pass a pre-shipment capacity and impedance test. We keep material traceability records and run two dedicated testing stations on the production line.
