4 Cost-Saving Benefits of a Li-Ion UPS

Posted by Enconnex Team on November 11, 2020

The increasing digitalization of business processes and growing demand for cloud services have driven significant growth in the construction of data centers. Because uninterruptible power supply (UPS) systems are essential components of the data center infrastructure, the construction of new data centers is driving growth in the UPS battery market.

According to a recent market research report by Technavio, the UPS battery market will see a compound annual growth rate of more than 8 percent, to exceed $3.2 billion by 2024. The research firm says that the use of lithium-ion batteries in UPS systems will have a positive impact on the market and contribute significantly to its growth over the next four years.


Why Lithium-Ion Batteries Help Drive UPS Market Growth

Maintenance of traditional valve-regulated lead-acid (VRLA) batteries is a major challenge for data center operators, particularly as their UPS deployments grow. VRLA batteries must be replaced every three to five years and monitored regularly to ensure availability and performance. Because UPS units are often powered by chains of VRLA batteries, one bad cell can cause the entire UPS system to fail. VRLA batteries are also heavy and take up significant space in the data center.

Lithium-ion batteries overcome these drawbacks while delivering significant value. Although lithium-ion batteries cost more initially, they can reduce the total cost of ownership (TCO) of UPS systems by up to 30 percent compared to VRLA batteries.


The 4 Benefits of Lithium-Ion Batteries


1. Long Cycle Life and Fast Recharge

VRLA batteries typically provide 200 discharge cycles, meaning that you can deplete and recharge the battery 200 times before it fails. Lithium-ion batteries offer 500 to 7,000 discharge cycles depending upon the chemistry and have a slow rate of discharge when not in use. VRLA batteries require up to 24 hours to fully recharge while lithium-ion batteries recharge in just two hours.


2. Lighter Weight

Because lithium-ion batteries have a higher energy density, they weigh about one-third less than comparable VRLA batteries. This makes them suitable for the upper floors of a multistory data center facility without the need to reinforce floors to handle the additional weight. The lighter weight also makes it easier to install lithium-ion UPS units in racks and cabinets.


3. Smaller Footprint

UPS units using lithium-ion batteries are typically about one-half the size of comparable VRLA-based UPS units. This 50 percent space savings can reduce data center construction costs and even make it possible to delay new buildouts. Lithium-ion batteries are also ideal for modular data centers.


4. Reduced Operational Overhead

The built-in battery management system (BMS) in lithium-ion UPS units provides status and fault monitoring, cell balancing, power optimization, and more, reducing the labor required for maintenance. It also helps reduce the risk of system downtime due to battery failure. Best-in-class lithium-ion UPS units also provide network connectivity for remote monitoring and management.
