Inside the J-Rong factory in Foshan, China
600 m² of production space, 3 automated assembly lines, 20 machines and 50 people — manufacturing lithium-ion phone batteries since 2010. Everything on this page was photographed on our own floor.
Fifteen years of doing one thing: phone batteries
Foshan Jurong New Energy Technology Co., Ltd. was established in 2010 at Beihai Science Park in Dali Town, Nanhai District, Foshan — the industrial belt that supplies much of China's consumer electronics aftermarket.
We started on domestic orders and still serve the Chinese market, which is why our quality bar is set by the most demanding repair market in the world. Since 2020 we have exported directly, and we now serve distributors and brand owners in Russia, India, Saudi Arabia, the United Arab Emirates, Nigeria and Vietnam.
We are vertically integrated from raw material procurement through to final shipment. That means one company is responsible for the cells that go in, the testing in the middle and the carton that arrives — not three suppliers blaming each other.
“We are a factory, not a middleman. Send me your model list and I will personally make sure the price and the quality are right.”

Four gates before a battery reaches your carton
Quality is not a final inspection at this factory — it is four checks placed along the line. Any unit that fails is pulled, not repackaged.
- Incoming screening — cells measured for capacity, voltage and consistency before release to production.
- In-process monitoring — station-level logging across clipping, labelling and printing.
- Two testing stations — first test after assembly, second test immediately before packing.
- 100% final inspection — visual and functional check on every single unit, plus batch capacity reports.
| 1. Incoming material screening | Every batch of cells and components is checked for capacity, voltage and consistency when it arrives, before it is released to the line. |
|---|---|
| 2. In-process monitoring | Operators log output at each station — clipping, labelling and printing — so a deviation is caught at the station, not at the end. |
| 3. First and second testing | Two testing stations on the line: a first test after assembly and a second test immediately before packing. |
| 4. Pre-shipment inspection | Finished cartons are sampled for capacity, impedance and appearance. We keep material traceability records for every batch. |
