Replacement Battery Kit for Liebert PSI5 UPS

The Vertiv PSI5-1100BATKIT is a new battery kit designed for Liebert PSI5 uninterruptible power supply units. It restores runtime when the original cells reach end of life. This kit suits IT managers and facility teams maintaining critical power infrastructure.

Verify UPS Model Before Ordering

Confirm the UPS label reads Liebert PSI5 before purchase. The kit is built for that specific product line and will not fit other series. Check the installation date of the existing batteries to plan a maintenance window.

Sealed Cells Deliver Steady Output

The replacement cells are sealed lead-acid units that operate without added ventilation noise. Normal use produces minimal heat inside the UPS enclosure. Power draw during recharge cycles matches the original specification.
