A battery is a device with one or more electrically connected electrochemical cells that is designed to receive, store, and deliver electric energy. An electrochemical cell is a system that consists of an anode, a cathode, an electrolyte, and any
connections that are needed to allow the cell to deliver or receive electrical energy. The term battery also includes an intact, unbroken battery from which the electrolyte has been removed.
A used battery becomes a waste when it is discarded. An unused battery becomes a waste when the handler decides to discard it. Batteries must be managed in a way that prevents releases to the environment.
Batteries that show evidence of leakage, spillage or damage that could cause a leakage must be placed in a container that is closed, structurally sound, compatible with the contents of the battery, and lacks evidence of leakage, spillage or damage that could cause a leakage.
Universal waste batteries (e.g., each battery) or a container in which the batteries are contained must be labeled with any of the following: “Universal Waste- Battery(ies)” or “Waste Battery(ies)” or “Used Battery(ies)”.
Personal household rechargeable batteries (e.g., lithium ion, nickel-metal hydride) can be taken for recycling at a local home improvement store.
