The biggest difference between the UPS and a lead acid battery is that UPS generates instantaneous power supply as soon as there is a power drop. The unit simultaneously powers up and supplies electricity without any delay, whereas a lead acid battery does not have such provision of uninterruptible power supply. Also, lead acid batteries generate direct current but UPS generates alternating current because, even though batteries in UPS also generate DC, but that is converted into AC by the inverter fitted in the UPS.
An uninterruptible power supply is mainly used where we require absolutely no delay in power cut and the backup supply. In lead acid batteries, there is a predetermined delay that can be afforded at that time. A lead acid battery is used where we need instant increase at the initial stage. Lead acid batteries are typically used in automobiles, but UPS can power whole buildings and institutions. UPS is also valuable when it comes to immediate surges in power or fluctuations in electricity because UPS filters the electricity and passes through only the consistent, conditioned electricity.
This unit has a surge protector on it but the instructions specifically say basically, “Hey! If you want sine wave power, this probably ain’t your best meow!”
So, smoothed out square wave, which I hear is brutal on electric motors. Anybody know more about this subject please post.
