Explore SLIOEM battery manufacturing
Dingwei Battery provides OEM and private-label battery programs manufactured by Chengguang Power Tech Co., Ltd. (founded 2002). OEM means your product is engineered, branded and supplied to an agreed specification — not picked from a generic catalogue.
OEM vs ODM vs private label
OEM builds to your specification; ODM starts from an existing design you can brand; private label applies your identity to a supplied product. The right path depends on how much of the specification you already control.
What “OEM” means for a battery buyer
OEM means you define the specification and own the design and brand; the factory manufactures to it. That is the difference from ODM (the factory owns the design) and private label (you brand an off-the-shelf product).

How to score an OEM battery manufacturer
Five dimensions separate a dependable OEM partner from a supplier that can only make one acceptable sample.
- Specification coverage — can they produce your standard (JIS / DIN / BCI / AS / SA)?
- Certification — is IATF 16949 in place for automotive supply, supported by ISO 9001?
- Scale — does factory area and daily output map to your annual volume?
- Repeatability — how do they keep repeat orders identical to the approved sample?
- Export experience — which markets do they serve, and what documentation do they provide?
Use this scoring view alongside the five-point decision framework before requesting samples.
Common OEM sourcing mistakes
- Comparing CCA across standards without checking the test method.
- Fixing the label before fixing the specification.
- Choosing the lowest price and ignoring repeatability.
Start with the OEM battery specification guide so the first approved sample becomes the standard for every later order.
FAQ
What batteries does Dingwei supply?
Dingwei supplies SLI, AGM, EFB and heavy-duty lead-acid starting batteries for OEM and private-label programs, with specifications to JIS, DIN, BCI, AS and SA standards.
Who manufactures Dingwei batteries?
Dingwei batteries are manufactured by Chengguang Power Tech Co., Ltd., a lead-acid manufacturer founded in 2002 in Jinzhou, Hebei, China, with IATF 16949 certification.
How does Dingwei keep repeat orders consistent?
Through a specification lock — the buyer approves a sample, and that approved standard becomes the benchmark for every later container. A gated process with pre-production sampling, in-process control and batch traceability prevents the specification drift that makes repeat orders come back different.
