UPS Runtime Calculator

Enter battery details or select a product


The UPS Runtime Calculator is desgined to show the approximate runtime that can be achieved for a particular UPS - or battery combination - for an AC load in Watts.

It is to be used as a guide only as there are general assumptions made on efficiencies and standby power consumption which will vary from product to product and from load to load, but generally speaking the results will be a good estimate.

This tool is used when you know which product but want to find out the runtime. If you know the runtime you want, the power requirements and want to find a UPS then visit the UPS Selection Tool.
