Two scenarios exist in which managers would need to replace a UPS. Either it has reached its load capacity, or a maintenance check has determined the batteries have reached their useful life and require replacement.
When it becomes apparent it is time to replace a unit, maintenance and engineering managers need to build a business case that analyzes both a simple payback and life-cycle costs. Providing both of these analyses will allow upper management to understand the financial impact and allocate funds for replacement. Managers can avoid providing maintenance and upgrades to old equipment by purchasing a newer technology unit that cuts labor costs and improves system reliability.
