All telecommunication nodes, from highly critical core sites to remote access sites, rely on standby batteries to keep systems up and running when utility power is disrupted or fails.
As batteries are subject to normal and abnormal aging and even occasional manufacturing defects, a battery testing and maintenance program is vital to ensure reliability. Several on-site and remote battery testing techniques are available, each with different costs as well as technical strengths and weaknesses.
By combining these different techniques and deploying them throughout the battery life cycle in a dynamic fashion - taking site criticality, age, battery size and previous test results into consideration - it is possible to design an optimized maintenance regime that will deliver improved battery reliability that is fully cost effective.
