Discover the advantages of lithium ion batteries in uninterruptible power supply applications. Mitsubishi Electric offers multiple lithium battery backup solutions, compatible with various sized UPS.
Lithium Ion power for UPS offers an extended lifespan, increased power density and smaller footprint. Many customers are now looking beyond VRLA batteries for their mission critical applications. Lithium ion solutions provide many features that greatly exceed the capabilities of traditional lead acid products. Not only are lithium ion battery backups more eco-friendly than their VRLA counterparts, they’re also more cost efficient, provide a higher power density in a smaller footprint, and have a longer life – one more in line with the lifespan of a Mitsubishi Electric UPS. This means less battery replacements over time. UPS lithium ion batteries also require less energy to keep them charged. Learn more about the advantages of lithium ion batteries in your UPS below.
When comparing battery technologies, it’s important to consider not only immediate runtime minutes, but also the total life span of different solutions. You need a battery backup that not only supports critical functions for an appropriate duration during an outage, but one that can do so consistently over the course of several years before a replacement is required. Compare UPS battery cabinet runtime minutes and life spans below:
With a 40-60% smaller footprint and 60% lower weight than VRLA, lithium ion battery backups for UPS take up less space that can be leveraged for critical equipment. Plus, their lighter weight makes them easier to transport. With lithium ion UPS backups, you don’t have to sacrifice power for space either. Our lithium ion battery cabinets have power density 4X that of VRLA, so they are able to do even more in a smaller space. This high discharge power and small size makes them a perfect solution for edge data centers.
However, cost and footprint aren’t the only reasons to choose a lithium ion battery backup for your UPS.
The less you have to replace your battery, the lower your battery budget can be over time. Upfront cost matters of course, but it needs to be considered in conjunction with replacement costs over time. The extended life span of a lithium ion backup power supply offers a significant advantage over VRLA with its longer life – 3X VRLA’s life span.
Fewer replacements mean fewer outlays of cash down the road. In fact, although a lithium ion solution may have a higher initial cost, a total cost of ownership analysis shows lithium ion as the preferred energy solution over the lifetime of the equipment – a 40% reduction over VRLA.
LONGER OPERATING LIFE
Life span of 15-25 years before reaching end-of-life (60% capacity). No battery replacements are expected over the lifetime of the UPS.
5-6x lighter than VRLA solution with equivalent energy. Provides cost savings and flexibility in shipment, installation, and facilities.
96% efficiency provides more cost savings over the lifetime of the UPS and batteries.
A visual inspection is recommended only once a year. Battery replacement services not expected over the lifetime of the UPS system.
HIGH ENERGY DENSITY
3-5x the energy density of VRLA providing the equivalent amount of energy in significantly smaller footprint providing more flexibility in facility installation.
LiB batteries include integrated battery management; providing real-time data and trending as well as safety monitoring and control.
HIGHER CYCLE LIFE
LiB possesses the ability to be cycled 25x more than VRLA, enabling longer life span, peak shaving, and grid stabilization capabilities.
Peak shaving saves utility costs by supporting load at peak demand. Batteries are discharged during peak demand and recharged during lower cost periods.
LONGER SHELF LIFE
Shelf life of 2 years before recharging is required. Increases options for timing of purchase and installation.
LOWER TCO OVER 20 YEARS
Over 65% of the total cost of ownership of the UPS system is reduced by lower maintenance, no battery replacement, and lower operating costs.
We offer multiple UPS lithium battery solutions, each with its own virtues, depending on your particular run time requirements, UPS size, and power needs. Convenient links to the data sheets for each are provided below:
The BCL04 is available with one of two different lithium battery backups. Each would be well-suited to support a UPS in standard or edge data center applications.
The codes and regulations for lithium ion batteries are currently changing. The National Fire Protection Association (NFPA) and International Fire Code (IFC) added sections directly related to the installation and use of lithium ion batteries. In combination with these, UL and IEC have created requirements for lithium ion batteries to ensure their safe use and operation in energy storage systems. Mitsubishi Electric can help you navigate the latest information and codes.
