This rule establishes standards of performance which limit atmospheric emissions of lead from new, modified, and reconstructed facilities at lead-acid battery plants.
Lead acid batteries were first established as a performance standard on January 14, 1980. New source performance standards were first proposed in 40 CFR part 60, subpart KK for the Lead Acid Battery Manufacturing source category on this date ( 45 FR 2790 ). The EPA proposed lead emission limits based on fabric filters with 99 percent efficiency for grid casting and lead reclamation operations.
1. NSPS The EPA has found through the BSER review for this source category that there are 40 existing lead acid battery manufacturing facilities subject to the NSPS for Lead-Acid Battery Manufacturing Plants at 40 CFR part 60, subpart KK.
The lead acid battery manufacturing source category consists of facilities engaged in producing lead acid batteries. The EPA first promulgated new source performance standards for lead acid battery manufacturing on April 16, 1982.
The EPA is proposing to include in the Lead Acid Battery Manufacturing NSPS subpart KKa compliance provisions to require owners or operators of lead acid battery manufacturing affected sources to conduct performance tests once every 5 years.
There are 40 Lead Acid Battery Manufacturing facilities in the United States. They are located across 18 states and are owned by 19 different entities. There is a significant size range across the parent companies: From about 20 to 150,000 employees, and annual revenues from about $4 million to $47 billion.
The EPA is aware of some facilities that conduct lead acid battery manufacturing processes but do not produce the final product of a battery. These facilities are not considered to be in the lead acid battery source category, and their processes are not subject to the lead acid battery NESHAP.

This comprehensive resource covers everything from the basics of Lithium-ion battery systems to the intricacies of safety, design, and regulatory requirements.
Due to the potentially hazardous nature of lithium batteries, these lithium-ion battery testing standards assure carriers that relevant products are safe to transport. Central to these standards is temperature cycling. These tests expose lithium batteries from -40C to 75C using 30-minute transitions.
The International Electrotechnical Commission (IEC) has developed several essential standards—IEC 61960, IEC 62133, IEC 62619, and IEC 62620—that govern the design, testing, and utilization of lithium batteries. This guide provides a detailed overview of these standards, highlighting their significance in the industry.
Battery test standards, including by IEC, SAE, and UL, guide manufacturers at every stage of the design process. Various testing models exist to verify safe operation in real-world conditions for industries as diverse as automotive, aerospace, and health care.
The specified test procedures enable the determination of the essential characteristics of performance, reliability and abuse of lithium-ion battery packs and systems. They assist the user of ISO 12405-1:2011 to compare the test results achieved for different battery packs or systems.
Central to these standards is temperature cycling. These tests expose lithium batteries from -40C to 75C using 30-minute transitions. Throughout the test, metrics like voltage, current, and electrical performance are monitored. Batteries that pass this test must fulfill specific criteria, such as the absence of deformation and leakage.
The main abuse tests (e.g., overcharge, forced discharge, thermal heating, vibration) and their protocol are detailed. The safety of lithium-ion batteries (LiBs) is a major challenge in the development of large-scale applications of batteries in electric vehicles and energy storage systems.
