Battery Technology for Single Phase UPS Systems: VRLA vs. Li-ion

Did you know? Li-ion battery prices have decreased over the years and are now becoming a viable option for UPS applications. Lithium-ion (li-ion) batteries have been used commercially for over 20 years in various applications. Why then have they not been commonly adopted as batteries for single-phase UPSs? The answer lies in the fact that, like all other applications, li-ion cells weren’t available that provided UPS vendors with the right balance of price, energy density, power, safety, and reliability for single-phase UPS applications. However, advancements in li-ion chemistries and technologies over the last 10 years have provided UPS vendors with [...]
