![]() The BMS optimizes battery charging on an ongoing basis, to maximize performance and increase the life of the battery. Unlike VRLA batteries, lithium-ion batteries have an integrated battery management system (BMS) that protects battery cells against temperature, current, and over- or under-charging issues. Integrated battery management system (BMS) That reduces the overall risk that you’ll suffer another outage before your UPS batteries have been fully charged. While VRLA batteries can take over 12 hours to charge from 0% to 90% of full runtime capacity, lithium-ion batteries take only 2 to 4 hours. Once it is called upon to provide backup power, the UPS battery needs to be recharged, as quick as possible, to full capacity. With edge computing and smaller data center space at a premium, this can make a significant difference in the protection of these applications. The smaller size of lithium-ion UPS batteries also enables companies to get far more runtime in the same amount of space – or the same runtime in a smaller space. That makes the UPS and its batteries far easier to install in racks or elsewhere, providing flexibility in terms of installation options. Lithium-ion batteries are also 40% to 60% lighter than their VRLA counterparts and about 40% smaller in size. This translates into being able to use UPS’ with Lithium Ion batteries in more non-traditional, harsher, environments (e.g., industrial and Edge applications). Lithium-ion batteries can function at temperatures of up to 104☏ with no performance problems. For every 15☏ temperature increase above 77☏, VRLA batteries lose about half their life expectancy, leading to a significant loss of performance. Lithium-ion batteries can also withstand higher temperatures than VRLA batteries with no performance degradation. 200 to 500 cycles – which again adds up to 8 to 10 years of life for lithium-ion batteries. VRLA batteries, 3,000 to 5,000 cycles vs. Additionally, lithium-ion can withstand more charge/discharge cycles vs. That may mean you never have to replace the battery throughout the life of the UPS, which saves on operational costs and reduces the risk of downtime during maintenance. Whereas the typical lifespan of a VRLA battery is 3 to 5 years, lithium-ion UPS batteries can last 8 to 10 years (or more) – often as long as the UPS itself. Lithium-ion batteries last up to twice as long as VRLA batteries. While valve-regulated lead-acid (VRLA) batteries have served the industry well for decades, the benefits of using lithium-ion batteries for UPS systems are simply too great to ignore. Lithium-ion is game-changing battery technology when it comes to uninterruptible power supply (UPS) systems. Integrated Battery Management System (BMS) – remote monitoring.Able to withstand higher operating temperatures.Up to 50% Total Cost of Ownership (TCO) savings.Faster recharge time – less time to be ready for another power failure.Smaller size – same performance in a smaller package.As compared to VRLA batteries, there’s a lot to like about Lithium-ion batteries:
