The test is non intrusive and can be completed without having to dismantle the battery string saving time and money. Having this advanced battery testing completed as part of ongoing normal maintenance builds a picture and a history for every battery in a string, giving early warnings to failure and anomalies at a fraction of the price compared to an installed monitoring system. Identifying a bad battery in a string early can not only prevent failure at a critical moment but also ensure the entire battery string isn’t put in danger of being damaged by one single bad block. #Eaton galileo runtime license fullįollowing each test a report is compiled that identifies each battery tested and its condition, comparing this information with past tests will indicate the current health level of the battery set and help determine when the batteries need budgeting for full replacement.īattery impedance testing has long been the way for a non intrusive test on UPS batteries. Placing a special tester across each battery takes a measurement of the battery internal resistance, this reading can be compared to the manufacturers specifications or previous readings to give an indication of the battery health. Sulfation and grid corrosion are main factors for the internal resistance rising.
