VERTIV Liebert PSI5 Lithium-Ion Sinewave Rack/Tower UPS 1920VA/1920W

Lithium-ion technology delivers up to three times the life of lead-acid batteries along with a lower total cost of ownership, making the Liebert PSI5 Lithium-Ion line-interactive UPSs ideally suited for server rooms, network closets, and other edge or distributed IT applications.Lower Total Cost of Ownership (TCO)
The Liebert PSI5 Lithium-Ion line-interactive UPSs are ideally suited to protect critical infrastructure in edge or distributed IT applications. The life expectancy of Lithium-Ion batteries is up to three times that of VRLA batteries - up to 10 years. That delivers 50% or more in TCO savings vs. VRLA batteries, chiefly because the Liebert PSI5 Lithium Ion requires fewer battery replacements over its lifespan. You save not only on the cost of batteries but on the labor required to replace them - an especially significant issue at remote locations with few or no IT personnel on site. In short, the Liebert PSI5 Lithium-Ion UPS is a true low-maintenance, set-it-and-forget-it solution.Lithium-Ion Battery TechnologyLithium-ion is a game-changing technology when it comes to UPS batteries. When compared to traditional valve-regulated-lead-acid (VRLA) batteries, Lithium-ion batteries have greater power density, last up to 3 times longer, recharge much more quickly, and can endure up to 10x more discharge cycles. Significantly more runtime, the Liebert PSI5 Lithium-Ion UPS is at the top of its class.
Liebert PSI5 Lithium-Ion Key Benefits vs VRLA• Up to 3x battery life• Lowest TCO• Longer Runtime• Quicker recharge times• Smaller and lighter: Greater power density, Reduced unit depth• Up to 10x more discharge cycles• Greater battery performance in higher temperature environments
