Stationary batteries require periodic maintenance to ensure reliability and safety of operation. Such battery systems include vented, VRLA and nickel cadmium types. These are the majority of batteries employed in standby service today. Join Rick Tressler for a one-hour class on recommended tasks, measurement intervals, capacity testing schedules as well as visual inspection criteria. Topics relating to each battery type are referenced to the applicable IEEE standard. These documents are the cornerstone of an industry recommended maintenance program.
