UL 62133-1 PDF

1 Scope

This part of IEC 62133 specifies requirements and tests for the safe operation of portable sealed secondary nickel cells and batteries containing alkaline electrolyte, under intended use and reasonably foreseeable misuse.

This standard is not, by itself, generally suitable for the evaluation of the safety of end-products, as it lacks specific requirements regarding charging, the effect of normal loads, abnormal conditions that should be considered, and the physical and electromagnetic stresses encountered in the anticipated environment of the end-product.

NOTE Battery packs with additional features or circuitry, including integral circuitry that facilitates charging, are considered to be end-products.

This standard deals with the covered components used in accordance with CAN/CSA-C22.2 No. 0.
