Recycling & Reuse Options
In Georgia, automobile batteries must be returned to retailers for recycling. Battery retailers are required by state law to accept old lead-acid batteries when you purchase a new one. They may also be taken to the County's Candler Road Landfill or Hall County Recycling Center for recycling.
Automobile batteries, under state law, may not be legally disposed of in landfills. They must be recycled.
