Key Features

• 100% Compatible: Designed as a direct replacement for the Liebert GXT4 1500VA GXT4-1500RT120 so it fits existing trays and connectors without modification.
• Plug & Play Ready: The pack ships charged and ready for use, allowing technicians to replace batteries quickly and return equipment to protected operation.
• Maintenance Free: Sealed lead acid, non-spillable construction eliminates regular electrolyte checks and reduces handling risk in server rooms.
• Hot Swappable: Supports replacement while the UPS remains online so there is no planned downtime for critical systems during service.
• Warranty Included: A one year warranty provides short-term protection against early failures and gives buyers confidence in initial reliability.

Who It's For

This replacement battery pack suits IT managers, small business owners, and facilities teams who run a Liebert GXT4 1500VA UPS and need a ready-to-install spare. The hot swappable and charged nature of the pack makes it especially useful where uptime is essential and scheduled outages are undesirable.

It is less suitable for users seeking long-term battery life data or extended service plans from the vendor; those buyers may prefer OEM-backed extended warranties or batteries specified directly by the original manufacturer for full lifecycle support.
