Car batteries are recyclable. According to the Battery Council International, 98 percent of all battery lead is recycled, making lead-acid batteries one of the most highly recycled consumer products.
Most new lead-acid batteries contain 60 to 80 percent recycled lead and plastic. The lead and plastic in most lead-acid batteries has been recycled many times and can be recycled many more times.
Most drivers return their used car batteries to the store when they need new batteries. The store then ships the used battery to a permitted recycler in accordance with state and regional environmental regulations. Most stores provide this service for free when drivers purchase new batteries.
