EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of IEC EN 62877-2 testing. IEC EN 62877-2 applies to vented lead-acid cells and water for use with batteries, i.e. water for preparing electrolyte and filling cells or batteries.
The purity of the refill water should meet higher requirements compared to the filling electrolyte, because the impurities in the working electrolyte will gradually increase with regular addition of water. This international standard lays down requirements for the composition, purity and properties of water without specific recommendations from the manufacturer.
Water should be stored in suitable containers such as containers made of glass, ebonite, polyethylene, polypropylene or other plastic materials. Hoses should be made of PVC, rubber or polyethylene.
Dissolution of metal ions from metallic containers can occur. Therefore, containers made of metal should not be used. Since carbon dioxide (CO2) absorbed from the air increases the electrical conductivity of purified water, it is always recommended to store the purified water in airtight containers.
The standard specifies the quality requirements for water used in vented lead-acid accumulators, including the chemical and physical properties of the water. The water used must be free of impurities such as minerals, salts and organic substances that may damage the accumulator and affect its performance.
The standard also provides guidance on how to test the water used in vented lead-acid accumulators to ensure it meets the required quality standards. The test includes measuring pH, conductivity, total dissolved solids and other parameters of water.
In addition, the standard outlines procedures for the handling, storage and handling of water used in vented lead acid accumulators. This includes guidelines on how to avoid contamination of the water during these operations.
By complying with the requirements set out in IEC EN 62877-2, manufacturers can ensure that the water used in vented lead-acid accumulators meets the quality standards required to ensure optimum performance and longevity of the accumulator.
