Lithium Battery Total Cost Calculator
A lithium battery costs more upfront but is usually replaced far less often. Put in what you actually pay today and see how the two compare over time — the calculation uses your numbers, not ours.
Your assumption. The warranty is 5 years; LiFePO4 cells are commonly rated well beyond that, but actual life depends on use.
Over 10 years, on your numbers
On these inputs, LEGACY LFP-12V-150AH works out ₹29,500 cheaper over 10 years.
This compares purchase cost only, using the figures you entered. It deliberately excludes electricity, maintenance, and installation — those vary too much to estimate for you.

This is deliberately a simple purchase-cost comparison: how many batteries you'd buy over the period, times what each costs.
It does not estimate electricity costs, water top-ups, maintenance visits, or installation — those depend on your tariff, usage, and local rates, and we'd rather show you nothing than invent a number. If those matter to your decision, factor them in yourself.
Replacement frequency and expected lithium life are your assumptions. Change them and the comparison changes with them.
