Vertiv GXT5-6000RT208 vs Vertiv GXT5LI-6000GVRT3UXLN: Specification Comparison
Both the GXT5-6000RT208 and GXT5LI-6000GVRT3UXLN are Vertiv GXT5-series 6000VA online double-conversion rack UPS units with hardwired input, targeting data center and critical IT infrastructure installations. The central differentiator is battery chemistry: the GXT5-6000RT208 is a VRLA-based unit designed to accept pre-installed GXT3/GXT4 battery pods, while the GXT5LI-6000GVRT3UXLN uses lithium-ion chemistry. Buyers cross-shopping these two are typically weighing battery runtime flexibility, form factor, input voltage range, and agency certification against total cost of ownership and footprint.

How do the two units compare on power rating, input voltage range, and output configuration?
Both units share an identical nameplate rating of 6000 VA / 6000 W, so neither has an advantage in raw capacity at the 6kVA tier.
The GXT5LI-6000GVRT3UXLN specifies an input voltage range of 200V–240V and a hardwired L1-L2/N-G wiring topology. Output is 230VAC default, user-configurable to 200–240VAC, with a stated regulation of ±1%. No equivalent input voltage range or output configurability data is provided in the GXT5-6000RT208 specifications as supplied; those specs list a broader model family power table rather than electrical parameters for the specific SKU.
For installations requiring confirmed input/output voltage flexibility or tight output regulation figures, the GXT5LI-6000GVRT3UXLN provides documented numbers. The GXT5-6000RT208 input/output parameters are not available in the provided spec set and cannot be assumed.
What are the physical footprint, weight, and operating environment differences between these two units?
The GXT5LI-6000GVRT3UXLN has documented physical dimensions of 5.25 in H × 16.9 in W × 35 in D (3U rack form factor implied by height), a weight of 99 lbs, and an operating temperature range of 32°F to 104°F (0°C to 40°C), with a 10% derating noted at 50°C.
No physical dimensions, weight, or operating temperature data are provided in the supplied specifications for the GXT5-6000RT208. Buyers who need to verify rack space consumption, floor load, or thermal envelope for the GXT5-6000RT208 must obtain those figures from the manufacturer datasheet directly.
The lithium-ion GXT5LI-6000GVRT3UXLN's 99 lb weight at 6000VA is consistent with Li-ion battery packs being lighter than equivalent VRLA configurations, but a direct weight comparison cannot be made without GXT5-6000RT208 weight data.
How do battery chemistry, expansion architecture, and agency certifications differ between the two models?
The GXT5-6000RT208 is explicitly designed for use with pre-installed GXT3/GXT4 battery extension pods, indicating a VRLA (lead-acid) architecture with a modular runtime-expansion path using existing GXT3/GXT4 pod inventory. This is a meaningful advantage for sites that already own compatible pods or require granular runtime scaling.
The GXT5LI-6000GVRT3UXLN uses lithium-ion chemistry. Li-ion cells offer a longer cycle life, reduced weight, and tolerance for higher ambient temperatures compared to VRLA, though the battery expansion architecture for this unit is not described in the provided specs.
On agency approvals, the GXT5LI-6000GVRT3UXLN carries a detailed certification list: IEC 62040-1:2008+A1 2013, IEC 62619 1st Ed., IEC 62040-2 2nd Ed., IEC 61000-3-2, IEC 61000-3-12, CISPR22 Class A, FCC Part 15 Class A, and UL 1778. No agency certification data is provided for the GXT5-6000RT208 in the supplied spec set.
Which should you choose: the GXT5-6000RT208 or the GXT5LI-6000GVRT3UXLN?
Our take: The GXT5LI-6000GVRT3UXLN is the stronger documented choice when a buyer requires confirmed electrical parameters, agency certifications, and lithium-ion battery longevity — the GXT5-6000RT208 is the stronger choice when a site already owns GXT3/GXT4 battery pods and needs to maximize runtime through pod reuse. On the specs provided, the GXT5LI-6000GVRT3UXLN supplies a documented input range of 200V–240V, a user-configurable 200–240VAC output at ±1% regulation, UL 1778 and IEC 62040-1 certifications, and a 99 lb / 3U physical footprint — none of these figures are available in the GXT5-6000RT208 spec set as provided. The GXT5-6000RT208's key differentiator is its pre-installed GXT3/GXT4 pod compatibility, which offers a proven VRLA runtime-expansion path. Sites standardizing on Li-ion for reduced maintenance and longer cell life should favor the GXT5LI-6000GVRT3UXLN; sites with existing GXT3/GXT4 pod infrastructure should evaluate the GXT5-6000RT208.
