Vertiv PS3-90-36VBKIT Replacement Battery Kit for PS1500RT3 | UPS Batteries

Keep your PS1500RT3 UPS ready for the next outage with a replacement battery kit engineered for direct compatibility. When battery capacity declines, runtime drops with it. Replacing the battery assembly is the fastest way to recover protection without the cost and disruption of a full UPS refresh. This Vertiv kit is built for environments where uptime matters: branch networks, telecom closets, security systems, and distributed infrastructure that cannot afford avoidable downtime. It preserves the original UPS footprint while restoring the battery subsystem that carries critical loads through utility loss, brownouts, and short transfer events. For procurement teams, the value is straightforward: extend the service life of an installed UPS platform, reduce replacement spend, and keep maintenance predictable. For operations teams, it means a cleaner service event and a faster return to full backup capability. If your PS1500RT3 is still the right UPS for the job, this battery kit helps it stay that way.
