Some FAQ about the Lithium batteries for UPS

Apr , 06 2022

What are the primary benefits of switching to lithium based UPS batteries? The most common reason cited is the significantly longer service life. Lithium also provides a greater cycle life (the number of charge/discharge cycles ranges from extends into the thousands, versus approximately 500-600 for VRLA batteries), as well as a longer warranty. Furthermore, the lighter weight and smaller footprin...

Battery charging tutorial-Part 2

Apr , 18 2022

Equalization Equalization is essentially a controlled over charge. Some charger manufacturers call the peak voltage the charger attains at the end of the BULK mode (absorption voltage) an equalization voltage, but technically it's not. Higher capacity wet (flooded) batteries sometimes benefit from this procedure , particularly the physically tall batteries. The electrolyte in a wet battery can str...

Efficiency of DC power system

Jun , 27 2022

In this article we will explain the efficiency of DC systems and progress to AC systems on the next article. In very basic terms, efficiency is the measure of how much power is not being wasted by a system. More waste is less efficient. In electrical systems, we measure the power entering a system in watts; the unit of measure for work performed. Efficiency is the ratio of (Power-In) -vs. - (Power...
