BS EN 62877-2:2016 applies to water for use with vented lead-acid cells and batteries, i.e.
water for preparation of electrolyte and for topping up cells or batteries.The purity of refilling water has to meet higher requirements compared to filling electrolyte,
because the impurities in the operating electrolyte will be gradually increased by regular
addition of water.This international standard lays down requirements of the composition, purity and properties
of water in the absence of specific recommendations from the manufacturer.Cross References:IEC 62877-1EN 62877-1IEC 62485-3EN 62485-3IEC 62485-2All current amendments available at time of purchase are included with the purchase of this document.
