Choose the Right Battery Backup System

Mitsubishi Electric offers several energy storage options for our uninterruptible power supply systems.

Identifying the correct battery or backup power supply for your UPS is paramount to supporting your critical load during a power quality event. Optimal battery backup systems prevent downtime over an extended lifetime with minimal footprint – but they should also be customized to your needs. To select the right battery backup system for your critical power requirements, you must consider:


Upfront costs


Total cost of ownership

We understand making this choice is challenging; our team members are readily available to assist you to determine the power and performance you need from your battery backup system. Review our UPS battery solutions below to learn more.

Lithium Ion UPS Batteries

Lithium Ion batteries (LiB) are quickly becoming the preferred energy storage solution due to advantages, such as long life, small footprint, reduced maintenance and integrated battery monitoring system (BMS).

They offer the advantages of the extremely energy dense lithium ion chemistry with superior control and monitoring. Lithium ion solutions provide five times the capacity of lead acid batteries in 40%-60% of the floor space with significantly less weight.

Although the initial cost of the lithium ion system is higher than a traditional VRLA system, the 15-to-25-year lifespan facilitates a lower total cost of ownership over the life of the battery backup system.

Lead Acid UPS Batteries

Mitsubishi Electric offers a full range of battery and DC power solutions from top vendors, allowing us the flexibility to meet our customers’ requirements for their battery backup power supply.

  • VRLA (valve-regulated lead acid)
  • VLA (vented lead acid) also referred to as wet cells or flooded cells
  • Pure Lead

UPS Battery Monitoring

Battery failure is the leading cause of UPS load loss during a power outage, so monitoring and maintaining your UPS batteries is key to making sure your critical load is supported. Through the use of a BMS, you can proactively check the health of your battery backup system instead of merely reacting when a problem occurs.

For lead acid batteries that are more prone to thermal runaway, it is important to consider a adding a monitoring system when purchasing your batteries. Deploying a BMS will not only reduce maintenance costs and unplanned outages, but also increase maintenance efficiency and battery life, while providing the ability to better manage replacement planning.

Mitsubishi Electric’s experts can partner with you to choose the BMS that provides you the data and peace of mind to know that your UPS batteries will be available when they are needed the most.
