Hong Kong Stocks in Focus | CALB (03931) Declines Over 6% Again as 177Ah Cell Batch Malfunctions Escalate Quality Concerns

Stock News07-24

CALB (03931) shares fell more than 6%, trading down 6.14% to HKD 16.66 as of the time of writing, with a turnover of HKD 68.59 million.

According to market news, on July 14, Xinhua Net reported that a large number of commercial vehicles equipped with CALB's 177Ah lithium iron phosphate cells have experienced safety failures, including battery bulging, a sharp drop in driving range, and sudden power loss during operation.

Data from the China Automotive Battery Innovation Alliance shows that in the first half of 2026, CALB ranked fourth in installation volume among domestic power battery manufacturers.

In response, CALB issued an announcement stating that some GAC Aion S vehicles have exhibited battery system failures under specific operating conditions. The company will open a dedicated maintenance channel, offering free battery system inspections, repairs, and maintenance services to vehicle owners.

Notably, according to media reports, the failures are concentrated in vehicles with mileage between 150,000 and 300,000 kilometers. This range is a sensitive period for many commercial vehicles, as it often falls just past or close to the expiration of the manufacturer's warranty.
