Liebert/Vertiv APS UPS – 554992G1 Battery Module – NEW 6 AH Batteries – Refurbished Case

Vertiv Liebert APS Hot-Swappable Battery Module – Part No. 554992G1

Designed for the modular Liebert APS 5-20 kVA UPS platform, the 554992G1 battery module delivers reliable runtime expansion. A pair of modules forms one 144 V DC battery string, sliding effortlessly into the APS frame to add capacity or replace aged strings in seconds.
These modules are improved with larger capacity batteries replacing the 5 Amp Hour stock versions with 6 Amp Hour upgraded cells resulting in longer runtime during power outages.

Key Features & Advantages

• Hot-swappable architecture – replace or add runtime without shutting down the UPS or the protected load.
• Modular scalability – two modules create a complete battery string; simply insert additional strings as your runtime requirements grow.
• 144 V DC nominal voltage matches Liebert APS charger and power-train parameters for maximum efficiency.
• On-board monitoring & isolation circuitry automatically removes a faulty module from the DC bus, preserving overall string integrity.
• User-replaceable latch handle and captive retaining screws speed service in confined rack or row-based installations.
