New UPS battery solutions provide an alternative to traditional lead acid batteries
Time to replace your UPS battery? Perhaps it’s also time to learn more about the new UPS battery solutions available on the market. Compare traditional lead acid vs. lithium ion backup power options by reviewing the information below. They are proven viable solutions and worthy of consideration when it's time to replace lead acid (VRLA and VLA) batteries.
The most commonly utilized backup power source for uninterruptible power supplies has historically been lead acid batteries, either VRLA (valve-regulated lead acid) or VLA (vented lead acid, also referred to as wet cell or flooded). However, lead acid batteries come with inherent challenges, including relatively short life span (4-5 years), extensive maintenance requirements (semi-annually), and excessive weight & size. These in part have triggered the development of alternative energy sources for UPS battery power.
One of the most notable alternatives to lead acid is a lithium ion battery. There are various chemistries of lithium ion solutions and several make ideal UPS backup power options. Mitsubishi Electric has studied the landscape of the available emerging chemistries and confidently offers three of the best in its product offering, each possessing its own unique benefits. When comparing a lead acid battery vs lithium ion, all three UPS battery solutions from Mitsubishi Electric offer advantages over VRLA, including extended operating time and energy density, reduced maintenance, and improved efficiency.
In addition to lead acid vs. lithium ion considerations, another option may be upgrading to pure lead batteries. In cases where an under five minute runtime is all that is needed, a pure lead solution can accomplish this with less cabinets and a smaller footprint than lead acid. Pure lead batteries deliver other desirable characteristics, such as prolonged lifespan, longer warranties, and higher tolerance for increased temperatures. Of course, these more appealing features come with a higher price tag, so you will need to assess your priorities before of making a selection.
