release. In another example, failure of DC system batteries supporting a call center knocked out some emergency services including the ability to field 911 calls. The pending battery failure in each of these cases would have likely been discovered with a timely inspection, or better yet, with remote monitoring.
Physical Inspection: Check the batteries for any signs of swelling, leakage, or corrosion. Ensure that the battery terminals are clean and free of oxidation. Capacity Testing: Perform regular capacity tests to assess the health of the batteries. Batteries that no longer hold a full charge should be replaced to maintain reliable backup power.
These variances need to be understood when selecting a monitoring system. A battery monitoring system should automate the IEEE recommended practices for battery maintenance and testing, offer multiple remote communication and alarm options, and facilitate complete and accurate maintenance records. 24×7 Battery Monitoring Server
