What is UL 1620?

UL 1620 is a widely recognized standard in the electrical industry that specifies requirements for primary (non-rechargeable) lithium batteries. It establishes safety and performance criteria for these batteries to ensure that they meet stringent quality standards. This article will delve into the technical aspects of UL 1620, shedding light on its significance and impact on the market.

The Purpose of UL 1620

UL 1620 was created with the primary goal of ensuring the safety of lithium primary batteries during their manufacturing, storage, transportation, and use. The standard provides comprehensive guidelines for battery manufacturers to follow, covering aspects such as construction, labeling, testing, and disposal.

By adhering to UL 1620, manufacturers can certify that their batteries comply with recognized safety requirements, instilling confidence in both consumers and regulatory authorities. This helps prevent accidents, such as explosions or fires, that may occur due to faulty battery design or manufacturing processes.

The Technical Requirements of UL 1620

UL 1620 encompasses various technical requirements that batteries need to meet to be considered safe and reliable. These include:

Cell Construction: The standard defines parameters for the physical construction of the battery, specifying materials, dimensions, and tolerances.

Chemistry: UL 1620 addresses the chemical composition of the batteries, ensuring the selection of suitable materials and preventing the use of hazardous substances.

Temperature Tolerance: The standard outlines temperature limits that batteries should withstand without posing any safety hazards.

Electrical Performance: UL 1620 sets criteria for the battery's electrical characteristics, including voltage, capacity, discharge rates, and self-discharge levels.

Packaging Requirements: The standard covers various aspects of battery packaging, such as labeling, marking, and instructions for safe handling and disposal.

The Impact of UL 1620 on the Market

UL 1620 has had a significant impact on the lithium primary battery market since its inception. By providing a reliable benchmark for safety and performance, the standard has promoted consistent quality and consumer protection.
