Do you need to speak to someone about Critical Power, Out of Band Management, or your IT at the EDGE?
Lead-acid batteries have long been the default backup power choice for the uninterruptible power supplies (UPS) that ensure the availability of data centers, communications equipment, and industrial processes. While they provide the power and reliability required for these applications, when supported with appropriate monitoring and maintenance practices, they have traditionally been regarded as the weak link in the critical power chain. They tend to be high maintenance, heavy and require frequent replacement. Now, lithium-ion batteries have emerged as a viable alternative and a growing number of users are evaluating this technology for UPS applications in mission-critical environments. As a leading global provider of critical infrastructure systems, Vertiv has worked with a range of customers considering lithium-ion batteries to address key considerations they face when deciding whether to move forward with this technology.
6 Key Benefits of using Lithium Ion UPS
More Compact and Lightweight
Lithium-ion batteries weigh 40% to 60% lighter and have a 40% smaller footprint than their VRLA counterparts. This translates into a remarkable power density level, where less space is needed to deliver the same amount of power.
Lasts Longer
Lithium-ion batteries have a significantly longer lifespan--around twice or thrice that of VRLA batteries on average. Compared to a traditional VRLA battery technology that typically lasts three to five years, lithium-ion technology can provide a battery service life of eight to ten years (or longer), often outlasting the UPS itself. This essentially makes the UPS almost maintenance-free with fewer or possibly no battery replacements throughout its lifespan. Unlike VRLA batteries, lithium-ion batteries offer a high life cycle, making it suitable for many applications where frequent charge and discharge cycles are expected.
Contributes to a Lower Total Cost of Ownership
Regarding the total cost of ownership (TCO), lithium-ion batteries can provide up to 50% savings over their life expectancy. This is primarily due to their longer lifespan, high-temperature resilience, reduced maintenance expenses (with fewer or no battery replacement), and reduced installation expenses. Although VRLA batteries can surely save you money upfront, think of the bigger picture and consider the TCO.
Faster to Recharge
UPS batteries need to be recharged as quickly as possible to full capacity. While VRLA batteries can take over 6 hours to charge from 0% to 90% of full runtime capacity, lithium-ion batteries take only around 2 hours to recharge. That reduces the overall risk of experiencing an outage before your UPS batteries have been fully charged.
The cutting-edge lithium-ion battery technology has gone a long way to the advantage of many industries. With the many benefits it offers, a lithium-ion powered UPS is a must-have to secure your critical operations and lessen your operational costs.
Resilient to Higher Temperatures
Lithium-ion batteries can operate normally at temperatures of up to 40ºC without compromising performance. This is a clear advantage of this battery technology over VRLA batteries, which shed off about half their lifespan for every 10ºC temperature rise over 25ºC.
Since lithium-ion batteries have a wide operating temperature range, they become convenient for more extreme, non-traditional settings and facilities that don’t have enough cooling capabilities.
Comes With Advanced Integrated Battery Management System
Lithium-ion batteries come with an advanced integrated battery management system (BMS). This provides an accurate picture of the battery's health and runtime and protects the battery cells against current, temperature, and over- or under-charging. The BMS continuously adjusts battery charging to make the most out of performance and battery life.
