Battery Backup Calculator
Instantly calculate how long your battery will power your load – Lithium or Tubular
Battery Backup Calculator
Plan your energy independence with our Battery Backup Calculator. This tool helps you estimate how many hours of backup your selected battery can provide for your connected load. Whether you are using Lithium-ion or Tubular Lead-Acid batteries, you can easily calculate total usable energy and backup duration.
Why Use a Battery Backup Calculator?
- Understand your battery’s real backup capacity.
- Compare Lithium vs. Tubular batteries for your needs.
- Plan backup for homes, offices, and solar systems.
- Avoid overspending by choosing the right size battery bank.
How It Works
The calculator uses your selected battery type, voltage, capacity (Ah), and connected load (Watts) to estimate total usable energy in kWh. Based on the depth of discharge (DoD) and efficiency, it gives you an accurate backup time in hours.
Note: Lithium batteries typically allow 85% usable capacity (DoD), while Tubular Lead-Acid batteries allow around 55% usable capacity.
Benefits of Using This Tool
- Get instant and accurate battery backup results.
- Supports multiple battery voltages (12V, 24V, 48V).
- Choose different Ah ratings to match your battery type.
- Perfect for solar systems, UPS, and home inverters.
Energy Independence Starts Here
Stop guessing and start planning. With this tool, you can decide the right battery bank size for your home or business. Get clear insights into how much backup time you’ll really get from your selected battery setup.
