Battery Savings Calculator India 2026

Free, instant calculators for every battery decision — EV vs petrol 5-year cost, solar battery payback, home inverter ROI, and e-rickshaw lithium upgrade payback. All numbers calibrated for India 2026 prices and usage patterns.

šŸš— EV vs Petrol — 5-Year Cost Comparison

Compare the total cost of owning an electric car vs a petrol car over 5 years, including fuel, servicing, insurance, and battery depreciation.
Average Indian urban commute: 30–60 km/day
Mumbai: ₹104 Ā· Delhi: ₹95 Ā· Chennai: ₹101
Typical hatchback: 15–20 km/l
Indian residential: ₹5–9/kWh
Nexon EV: ~7 km/kWh Ā· Punch EV: ~7.5
Punch EV starts ₹11L Ā· Nexon EV ₹16L
Comparable segment ICE car
EVs: ₹3,000–8,000/year (no oil change)
Typical ICE: ₹12,000–25,000/year
Calculations assume constant fuel price, electricity tariff, and usage. Does not include insurance, depreciation on purchase price difference, EV charging infrastructure cost, or home charger installation (typically ₹8,000–15,000 one-time). EV battery warranty assumed valid for 5-year period.

ā˜€ļø Solar Battery Payback Calculator

Calculate how long your solar + battery system takes to pay back in India, accounting for PM Surya Ghar subsidies and grid export credits.
Typical 2BHK home: 3–5 kW
On-grid 2026: ₹45,000–65,000/kW installed
Pair at 20–30% of solar capacity
LFP 2026: ₹18,000–25,000/kWh installed
India avg: ~4 kWh/kW/day (varies by state)
Industrial: ₹6–12 Ā· Residential: ₹5–9
Up to 3 kW: ₹30K/kW Ā· 3–10 kW: ₹18K/kW
Current annual electricity cost
Calculation assumes 90% solar self-consumption with battery, stable tariffs, and 0.5% annual panel degradation. Does not include net metering credits, maintenance costs (typically ₹2,000–5,000/year), or financing costs. PM Surya Ghar subsidy requires Discom approval and MNRE registration.

šŸ  Home Inverter Battery ROI — LFP vs Lead-Acid

Compare the 10-year total cost of LFP lithium inverter batteries versus traditional lead-acid tubular batteries for your home.
1 kWh LFP home battery: ₹15,000–25,000
150Ah tubular: ₹6,500–9,000
LFP: typically 8–12 years at home use
Tubular: 3–4 years typical in India
LFP: zero maintenance
Distilled water + terminal cleaning: ₹500–1,200/yr
Average Indian town: 20–60 hrs/month
Productivity/comfort value of 1 hr backup
Calculations are for a single battery unit. Real systems use multiple batteries in series/parallel. LFP savings are higher in hot climates (India summers reduce lead-acid life further). Does not include inverter cost (same for both options) or electricity cost for recharging.

šŸ›ŗ E-Rickshaw Lithium Upgrade Payback

Calculate how quickly you recover the extra cost of upgrading from lead-acid to lithium (LFP) batteries in your e-rickshaw.
60V 80Ah LFP: ₹60,000–80,000
4Ɨ12V tubular set: ₹15,000–22,000
Commercial operator: 60–120 km/day
Urban e-rickshaw: ₹3–4/km average
Lithium gives 20–30 km more per charge cycle
Commercial LFP: 4–7 years typical
Commercial lead-acid: 1–2 years typically
Typical commercial operator: 280–310 days
Calculations assume consistent daily usage and stable fares. Extra range savings assume all extra km translate to fares. Does not include cost of lithium-compatible charger (₹3,000–5,000 one-time) or financing. Lead-acid maintenance cost savings estimated at ₹800–1,200/year.
