Our Take

Best for: Owners of the Vertiv Liebert GXT5-3000LVRT2UXL UPS needing longer backup.

The Vertiv Liebert GXT5 External Battery Cabinet is a straightforward add-on for a specific UPS. Its job is simple: connect it to your compatible Vertiv GXT5-3000VA UPS, and it provides a bank of extra batteries to keep your equipment running longer during a blackout. This is not a UPS itself, but a dedicated extension for one. What stands out is the auto-detection feature, which simplifies setup by letting the UPS automatically recognize the cabinet and configure the runtime. The hot-swappable design is also a practical plus, allowing you to replace batteries without shutting down the connected systems. The main limitation is its exclusivity; it only works with that one specific UPS model, so it's not a universal solution. At this sale price, which is a deep discount from recent averages, it becomes a very compelling purchase for anyone who already owns the matching UPS and needs more peace of mind. The three-year warranty adds good value. Just be prepared for the logistics, as it weighs almost 500 pounds.

Price Analysis

At $429.03, this is a 38% discount off the list price of $691.74. More importantly, it's well below the 90-day average of $802 and the 180-day average of $960. With no all-time low data available, this current price appears to be a significant drop and a very good time to buy for extended runtime.
