This Internal 48V Battery Kit is designed to fit into Liebert GXT4-1500RT120 (1500V / 1350W) and GXT4-2000RT120 (2000VA / 1800W) power backup systems from Vertiv, replacing worn or damaged batteries. This 48V 9Ah Valve Regulated Lead Acid (VRLA) battery may be recharged to 90% in about 6 hours after a full discharge at 100% load, leading to automatic shutdown.

Please note that although the battery pack is hot-swappable, caution should be exercised during the procedure, since connected devices will be left unprotected from disturbances and power outages. Do not replace the battery while the UPS is operating in battery mode.
