What is a Lithium-Ion Battery Backup UPS?

Uninterruptible power supply, or UPS, is a device that provides power backup to IT equipment when power completely fails or drops low enough. Some types of uninterruptible power supply provide just enough time for a computer to save what the user is doing and power down while some can provide electricity for over an hour.

Traditional UPS are manufactured with lead-acid (or VRLA) batteries. Lithium-Ion battery technology has only been around since the 1980’s. It has only been in the past two decades that the technology has been applied to uninterruptible power supply. Luckily the technology has improved enough to allow smaller businesses and IT solutions organizations to implement in everyday applications.

Industries Using Lithium-ion UPS


Retail Edge deployments are an ideal fit for Lithium-Ion UPS technology. Many large retailers are incorporating these systems into individual store locations across the country where they have increased digital needs and require reliable backup in case of an outage, and don’t have to support the maintenance that is required with traditional VRLA systems.

  • Remote retail sites
  • Warehouses and distribution

With the increased requirements of education to rely on technology for remote learning, schools need to ensure their systems stay up and running. Many schools are seeing the benefit of lithium-ion UPS systems in their deployments due to the total cost of ownership and reduction of maintenance with each unit.

  • K-12 Schools
  • Higher Education


Manufacturing floors are continuing to further advance their technologies, and the IT to support the production lines needs to be close to the equipment it is supporting. Oftentimes, this results in IT infrastructure being put in places that weren’t traditionally designed for it. Manufacturers are continuing to adopt Lithium-ion UPS systems because they can withstand higher temperatures without degrading the battery.

  • Manufacturing floors
  • IT rooms at a manufacturer


From hospitals to local and remote offices, healthcare IT teams are being asked to support more demand than ever on their networks. The industry is turning to lithium-ion UPS systems to support the need for added runtime, reduction of maintenance, and overall efficiencies.

  • Private offices
  • Hospital IT rooms

Lithium-Ion Battery Backup UPS Advantages

Lower Total Cost of Ownership (TCO)

Taking into consideration the initial investment of a VRLA system in addition to the battery replacements and services that aren’t needed with lithium-ion UPS, you are able to reduce your total cost of ownership of your UPS system by 50%.

Longer Life and Runtime

The life expectancy of a Lithium-Ion UPS is 8-10 years, which is 4x longer than comparable VRLA systems. When the Lithium-ion battery needs a recharge, it can be complete in less than four hours.



Heat Resiliency

In instances where your racks are exposed to higher temperatures, such as manufacturing floors, lithium-ion batteries are a great option. These UPS systems can withstand higher temperatures without degrading compared to VRLA batteries.


For a much better performance, lithium-ion batteries are 40% to 60% lighter than VRLA counterparts. On top of being lighter, they are 40% smaller too. This makes lithium painless to install, easier to maintain, and significantly more flexible. Also, while typical lead acid batteries take 12 hours to charge to 90% full runtime capacity, lithium-ion only requires 2 to 4 hours.
