While the IEEE Standards reflect the ideal level of maintenance, Eagle Eye recognizes that battery users may have more stringent or less strict requirements and these can be accommodated and if necessary, a custom maintenance procedure can be written.
When the battery shows signs of degradation (decrease in 10% from last test) or is below 90% of the manufacturers rated capacity it is recommended that the batteries be capacity tested annually.
The discharge current will be maintained within +/- 1% until the battery voltage measured at the battery terminals equals an average of the required low voltage limit. (For example, 60 cells x 1.75V = 105VDC battery terminal voltage) A battery capacity test system will be used to conduct the discharge test.
In addition, Eagle Eye offers battery monitoring and testing equipment that can assist and automate many of the requirements for battery maintenance. Using a calibrated and properly rated meter, measure and record the DC float voltage and current at the battery terminals. Record the battery charger output current and voltage readings.
