UPS Runtime Calculator vs Battery Backup Time 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 Backup Time Calculator
Find out how long a battery bank will power your equipment during an outage, given voltage, capacity, and inverter efficiency. Ideal for sizing UPS systems, off-grid setups, and emergency power installations.
- Answers
- Backup Time (hours)
- Inputs
- Total Load Power, Battery System Voltage, Battery Capacity, Inverter Efficiency
