UPS Runtime Calculator vs Battery Runtime Calculator
Two calculators for the same neighbourhood of questions. Here is what each measures, what you feed in, and where you'd reach for one over the other.
UPS Runtime Calculator
Estimate how many minutes a UPS (uninterruptible power supply) will keep your equipment running on battery backup, based on battery capacity, connected load, and UPS efficiency. Use it when sizing a UPS for a server, computer workstation, or network equipment.
- Answers
- Runtime (minutes)
- Inputs
- Connected Load, Battery Capacity, Power Factor, UPS Efficiency
Battery Runtime Calculator
Estimate how many hours a battery will power a device based on its capacity, discharge depth, and system efficiency. Ideal for sizing backup power, solar storage, and portable electronics.
- Answers
- Runtime (hours)
- Inputs
- Battery Capacity, Load Current, Depth of Discharge, System Efficiency
