Designed for the modular Liebert APS 5-20 kVA UPS platform, the 554992G1 battery module delivers reliable runtime expansion and fast field serviceability. A pair of modules forms one 144 V DC battery string, sliding directly into the APS frame to add capacity or replace aged strings quickly and efficiently.
This remanufactured battery module case helps keep usable materials out of landfills, making this a planet-friendly purchase that supports repurposing and recycling rather than unnecessary disposal.
Unlike shelf-aged OEM or distributor stock, our battery modules are built to order using fresh, high-quality cells from our high-volume battery pack rebuild operation for strong performance, reliable service life, and maximum value from the moment they arrive.
These modules are improved with larger-capacity batteries, replacing the original 5 Amp-Hour stock cells with upgraded 6 Amp-Hour cells for longer runtime during power outages and improved UPS performance under load.
