The battery core charge at Walmart is a refundable deposit applied to the purchase of a new automotive battery. This charge incentivizes consumers to return their old batteries for proper recycling, ensuring environmentally responsible disposal of hazardous materials. The amount of this deposit typically ranges from $12 to $20, but can vary based on state regulations and store policies. For example, a new car battery priced at $100 might have an additional core charge of $15, bringing the initial total to $115.
The imposition of a core charge addresses the environmental concerns associated with disposing of lead-acid batteries. These batteries contain hazardous substances, including lead and sulfuric acid, which can contaminate soil and water if improperly discarded. The refund system encourages consumers to recycle their old batteries, allowing for the reclamation of valuable materials and the prevention of environmental pollution. This practice aligns with sustainable waste management principles and promotes a circular economy.
