Overview
IEC TR 62060:2001, published by the International Electrotechnical Commission (IEC), is a user guide focused on the monitoring of lead-acid stationary batteries, including both vented lead-acid (VLA) and valve-regulated lead-acid (VRLA) battery types. The guide is applicable across industries where stationary batteries are critical for backup, standby, or infrastructure support, such as telecommunications, utilities, and power supply systems. The document aims to assist users in selecting monitoring methods that efficiently indicate the state of health, reliability, and residual life span of stationary lead-acid batteries through the measurement and interpretation of key electrical characteristics.
