prEN IEC 62620:2026

This International Standard specifies marking, tests and requirements for lithium secondary cells and batteries used in industrial applications including stationary applications.
When there exists an IEC standard specifying test conditions and requirements for cells used in special applications and which is in conflict with this standard, the former takes precedence. (e.g. IEC 62660 (all parts) [4] on road vehicles).
The following are some examples of applications that utilize the cells and batteries under the scope of this standard.
– Stationary applications: telecom, uninterruptible power supplies (UPS), electrical energy storage system (EESS), utility switching, emergency power and similar applications.
– Motive applications: fork-lift truck, golf cart, automated guide vehicle (AGV), railway, and marine, excluding road vehicles.
Applications excluded from the portable use specified in the scope of IEC 61960-3.
NOTE EESS and UPS, which use batteries with electrical energy equal or lower than 500 Wh are excluded.
Since this standard covers batteries for various industrial applications, it includes those requirements, which are common and minimum to the various applications.
This document addresses first life cells and batteries. Reuse, repurpose, second life use or similar are not taken into consideration by this document.
Refer IEC 63330-1:2024 for second life batteries.
This document helps to clarify the concept of health, state of health and durability of secondary lithium industrial cells and batteries. See Annex B and Annex C.
