With the increasing emphasis on environmental protection worldwide, golf cart batteries, as a type of industrial battery, are subject to strict environmental performance requirements to minimize their impact on the environment during production, use, and disposal. The first core requirement is the restriction on harmful substances. According to international and national environmental standards (such as the EU’s RoHS directive and China’s Environmental Protection Standards for Batteries), golf cart batteries must not contain excessive amounts of harmful substances such as lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls (PBB), and polybrominated diphenyl ethers (PBDE). For example, lead-acid batteries, which are commonly used in golf carts, must strictly control the lead content in the electrolyte and plates, and the production process must be optimized to reduce lead emissions. For lithium-ion batteries, which are increasingly used in new energy golf carts, the content of cobalt, nickel, and other heavy metals must also meet environmental standards to avoid soil and water pollution caused by leakage.

The second environmental performance requirement is energy efficiency and resource utilization. Golf cart batteries should have high energy efficiency to reduce energy waste during charging and discharging. For example, the charging efficiency of the battery should be no less than 85%, and the discharge efficiency should be no less than 90%, ensuring that most of the electrical energy is converted into usable power for the golf cart. At the same time, the battery should be designed to be recyclable, and the materials used (such as lead, plastic, and metal) should be easy to disassemble and recycle. Manufacturers are required to establish a recycling system for used golf cart batteries, and recycled materials should be reused in the production of new batteries or other products to reduce the consumption of non-renewable resources and the generation of solid waste. For example, lead from used lead-acid batteries can be recycled and smelted to produce new battery plates, and plastic cases can be recycled and processed into new plastic products.

In addition, the environmental impact during the use and disposal of golf cart batteries must be minimized. During use, the battery should not produce harmful gases (such as hydrogen sulfide) that pollute the air, and the electrolyte leakage should be prevented to avoid soil and water pollution. For lead-acid batteries, the electrolyte (dilute sulfuric acid) should be sealed and stored to prevent leakage, and if leakage occurs, it should be treated with a neutralizing agent in a timely manner. During disposal, used golf cart batteries must not be discarded in landfills or incinerated at will. Instead, they should be handed over to professional recycling institutions that have obtained environmental protection qualifications for centralized treatment. The treatment process should comply with environmental standards, such as harmless treatment of electrolytes, recycling of valuable materials, and safe disposal of waste residues, to ensure that the entire life cycle of the battery does not cause significant environmental pollution. Some countries and regions also require manufacturers to assume extended producer responsibility, that is, to be responsible for the recycling and disposal of the batteries they produce, further strengthening the environmental management of golf cart batteries.
