2.0 Preparing for Maintenance
The battery system should be remotely monitored monthly and physically inspected quarterly. If the
battery system has an automatic monitoring system to gather the electrical and environmental data,
the monthly checks should consist of evaluating the recorded data and visiting any site that does not
meet the specications listed in the detailed procedures below. At a minimum each site needs to be
physically inspected every three months.
You do not have to measure the electrolyte specic gravity or add water to the cells.
All batteries in the string should be numbered to facilitate recording and analysis of data unique to
each unit.
Notify anyone affected by the intended maintenance or troubleshooting activity. This should include
but not be limited to anyone responsible for the status monitoring equipment at the head-end or NOC.
