What is this tool used for?
Use this calculator to compare how much nominal lithium or tubular lead-acid storage is needed for the same backup task. It explains why equal Ah labels do not necessarily provide equal usable backup.
How to use this calculator
Use one load, duration and bank voltage for both options. Enter each chemistry's permitted discharge depth and battery-to-AC efficiency from the proposed equipment specifications.
Understanding your results
The two capacity estimates aim to deliver the same AC energy. A smaller nominal capacity does not automatically mean a better purchase; this tool does not compare price, warranty, cycle life or replacement costs.
ગણતરીની રીત
પરિણામ વાપરતા પહેલાં
The defaults are illustrative assumptions, not universal specifications. Use the battery and inverter manufacturer data. This comparison excludes cycle life, cost and lead-acid discharge-rate derating.
Does the smaller bank always cost less?
No. Purchase cost, warranty, cycle life, temperature and replacement frequency also affect value.
