Used car batteries, as well as other used lead-acid batteries are hazardous waste and should be disposed of appropriately through recycling programs. Lead-acid batteries also include batteries in motorcycles, boats, emergency lighting and air conditioners.
A national network of Battery Recycling Centres has been established by Century Yuasa for environmentally responsible collection and recycling of used lead-acid batteries.
Most car workshops, scrap metal dealers and service stations will accept used car batteries for recycling. Check with your car battery vendor when purchasing a new battery.
Some states and councils provide Household Hazardous Waste or Chemical Collection programs that take used lead acid batteries for recycling.
