CALB Tackles Quality Concerns with Stricter Manufacturing Controls

CALB, China’s third-largest battery manufacturer, is implementing a comprehensive quality overhaul in response to recent criticism over its product reliability. The company has decided to tighten manufacturing tolerances and empower its quality assurance team with veto authority over batch releases, ensuring that no defective products reach the market without thorough review.

The move comes after a series of public complaints, often referred to colloquially as the ‘banana battery’ incident, which highlighted potential issues in certain battery cells. By restructuring its internal processes, CALB aims to restore consumer confidence and reinforce its position in the competitive energy storage and EV battery sectors.

Industry analysts view this as a proactive step that could set a new standard for battery manufacturers in China, where rapid production growth sometimes outpaces quality control measures. CALB’s commitment to stricter oversight signals a shift toward prioritizing long-term reliability over short-term output.
