IEC 62877-1:2023 is available as IEC 62877-1:2023 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.IEC 62877-1:2023 applies to electrolytes and their components used for filling vented lead acid batteries with dry-charged cells and for electrolyte replenishment, replacement or electrolyte density adjustment of batteries in operation. This document defines the composition, purity and properties of electrolyte, for application where specific instructions from the battery manufacturer are not available. This second edition cancels and replaces the first edition published in 2016. This edition includes the following significant technical changes with respect to the previous edition: – Addition of the concentration values of halogens in Table 4.
