About DINWEY
DINWEY is the truck and heavy-duty starting battery brand of Chengguang Energy, a manufacturer founded in 2002. We focus on one thing: starting batteries that hold up under the demands of commercial trucks — high cold cranking amps, vibration resistance, and consistent batch quality.
Our Focus
While many battery suppliers sell a broad catalog, DINWEY concentrates on the truck and heavy-duty vertical. That focus lets us go deep on what matters to commercial-vehicle buyers: correct group sizes (JIS N150/N200, DIN88/DIN100; BCI Group 31/8D on request), diesel-grade CCA, and 12V vs 24V system requirements.
The Factory Behind the Brand
DINWEY is manufactured by Chengguang Energy, a battery manufacturer established in 2002 in Jinzhou City, Shijiazhuang, Hebei Province, China. The factory spans 200,000 m² with 18 automated assembly lines producing 40,000 batteries daily, exporting to 70+ countries.
