BATTERY ASSAULT: U.S. battery maker Johnson Controls is at odds with Shanghai's environmental regulator over tests the company says show it was not responsible for severe lead poisoning cases in children discovered earlier this year.
BLAME GAME: Johnson said an investigation by the China Electric Equipment Industry Association found its battery factory in Shanghai's eastern suburbs was not the cause of elevated blood-lead levels among children nearby. It blamed a recycling facility in the area.
MORE DRIVERS, MORE BATTERIES: Soaring use of cars and electric scooters is driving demand for lead-acid batteries. Their production and recycling are a major source of lead contamination. China shut down hundreds of battery factories last spring after a slew of lead poisoning cases.
