description: "$CALB(03931.HK) dropped by eight points today, falling nearly 13% at one point during the session, with volume exceeding twice the average.The trigger was the escalation of battery defects in the GAC Aion S: models equipped with its 177Ah LFP cells were exposed to widespread failures, affecting ride-hailing drivers with extremely high operational mileage. GAC stepped forward first with a fallback plan, but there is still no word on how liability will be allocated among cell suppliers.Its growth story of just entering the top three in global installed capacity and doubling energy storage shipments has collided with its first major quality incident—questions remain on how recall costs will be shared, how customer trust can be restored, and whether future design wins will be impacted. All these await a formal response from the company. Quality incidents are never one-off costs for battery manufacturers; keep an eye on official statements and order trends moving forward."
