To calculate battery backup time, divide the battery capacity (C) multiplied by voltage (V) by the power load (P).
The Battery Backup Calculator aids you to determine the duration a battery can power a device based on its capacity, voltage, and power consumption. This calculation is vital for choosing the right battery size for uninterrupted power supply systems (UPS), solar installations, and various electronic devices.
By simply inserting your battery specifications and device power requirement, this tool immediately calculates the estimated runtime, aiding in backup planning and power management.
Formula
| Variable | Description |
|---|---|
| B | Battery backup time (hours) |
| C | Battery capacity (Ah) |
| V | Battery voltage (V) |
| P | Power load (W) |
Solved Calculations
Example 1:
| Step | Calculation |
|---|---|
| Battery Capacity (C) | 100 Ah |
| Voltage (V) | 12 V |
| Power Load (P) | 50 W |
| Backup Time Calculation | |
| Result | 24 hours |
Answer: With a 100 Ah battery at 12V and a 50W load, the backup time is 24 hours.
Example 2:
| Step | Calculation |
|---|---|
| Battery Capacity (C) | 200 Ah |

| Power Load (P) | 100 W |
| Backup Time Calculation | |
| Result | 48 hours |
Answer: With a 200 Ah battery at 24V and a 100W load, the backup time is 48 hours.
What is a Battery Backup Calculator?
The Battery Backup Calculator is a power-calculating tool. It is developed to estimate the runtime of a battery based on its capacity, voltage, and power usage. This tool is equally helpful for assessing a backup system for home, solar setups, or uninterruptible power supplies (UPS).
Moreover, this calculator enables you to estimate how long a battery will last under specified conditions, including different battery types like lead-acid, lithium-ion, or solar batteries.
To use this calculator, simply enter details such as the battery’s voltage, capacity (in ampere-hours), and the power draw of the device it’s powering. The calculator will then compute the estimated backup time, offering valuable insights for planning reliable power solutions for residential, commercial, or emergency backup systems.
Final Words:
To put it concisely, this Battery Backup Calculator is essential for making informed decisions on battery requirements, enhancing power management for uninterrupted energy support in various applications.
