Lithium Ion UPS

Selecting the ideal storage solution for an industrial process, critical infrastructure, critical building or a data center can be a daunting task. The backup storage solutions in use today are expected to maintain both manageability and availability or increase to increase them. However, all this should be achieved while decreasing UPS footprint. Lithium ion UPS strikes a perfect balance between safety, performance and cost. Every battery is made up of numerous cells and these depend on the required power. The cells of lithium ion batteries are each engineered as independent systems that operate in a parallel electronic topology.

Value proposition

Lithium-ion battery technology has greatly evolved and is currently financially viable for fresh applications as well as in larger applications like data centers and electric cars. The following are some notable value propositions for lithium ion UPS:

i. It greatly decreases the Total Cost of Ownership also known as TCO.

ii. It enhances both the manageability and predictability of backup storage.

iii. It is associated with decreased cooling requirements.

iv. It has a higher durability as well as reduced maintenance costs in comparison to traditional VRLA batteries. The cycle life of lithium ion battery exceeds 1000 cycles for UPS applications. Traditional lead-acid batteries have 200 – 400 cycles before they require to be replaced for new ones.

v. It decreases battery footprint and weight to a large extent thus promoting efficiency in space utilization. Lithium ion battery systems for UPS take up approximately 50% to 80% less floor space. In addition, these battery systems weigh less compared to lead-acid system i.e. 60-80%

vi. It has extremely fast UPS recharge.

vii. It also ensures scalability for power redundancies or upgrades.

Other benefits include the following:


Simplicity is what facilitates reliability in all systems. Lithium ion cells are characterized by simpler and fewer chemical processes. This allows for the use of detailed mathematical models by engineers in the prediction of performance of cells in difficult operating patterns.


Lithium ion batteries for UPS lack hazardous materials. This means that it is more environmentally friendly. Lead-acid batteries contain lead that is very harmful.


Maintenance requirements for Lithium Ion industrial Ups are quite low. This is because it lacks fluid levels to be measured and maintained. Furthermore, consumers do not have to be concerned with battery memory. The batteries do not need periodic cycling for calibration of their runtime. In fact, most lithium ion industrial Ups have a lifespan of 10+ years.

It should be noted that the level of cell design as well as the material quality of lithium ion batteries should always be suitable for intended applications for best performance. In addition, all lithium-ion batteries should have a battery management system due to a high sensitivity to the manner by which they are charged as well as discharged.


The main purpose of Uninterruptible Power Supplies is to provide data processing security. This means that a new UPS electricity storage technology ought to provide such opportunities and this is what lithium ion UPS is doing. The above insightful information clearly shows the numerous benefits lithium ion has compared with lead-acid batteries. Nonetheless, VRLA technology is still capable of effectively offering support to existing structures.
