CSA E61951-2:21 PDF Download

The CSA E61951-2:21 standard is an adoption of the IEC Standard 61951-2 with Canadian deviations. The standard specifies the marking, designation, dimensions, tests, and requirements for secondary sealed nickel-metal hydride small prismatic, cylindrical, and button cells and batteries. These cells and batteries are designed for use in any orientation and are intended for portable applications.

The standard provides guidelines for ensuring the quality and safety of nickel-metal hydride cells and batteries used in portable devices. It covers important aspects such as marking and designation to ensure proper identification and traceability. It also defines the dimensions of the cells and batteries to ensure compatibility with portable devices.

Additionally, the standard outlines the tests and requirements that the cells and batteries must meet. These tests assess various performance parameters and safety aspects such as capacity, voltage, internal resistance, and resistance to overcharge and overdischarge. By complying with these tests and requirements, the cells and batteries can be certified as safe and reliable for use in portable applications.
