🔋 EV Battery Replacement Cost Estimator

Plan for the post-warranty bill — pack, labour, GST, module repair & monthly reserve.

Why it matters: The traction battery is typically 30–40% of an EV’s cost, and post-warranty replacement fear is a top ownership barrier (Deloitte 2025). This tool turns that anxiety into a shareable ₹ estimate — and pairs with degradation timing so you know when to budget, not just how much.

📋 Vehicle & pack

Carmakers rarely publish a rate card. Use a preset, then override with a written dealer quote when you have one. Pack override is pack-only (ex-labour); labour, GST and scrap are added below.

Aftermarket packs can void remaining vehicle warranties and may lack OEM thermal/BMS calibration. Module repair is workshop-dependent — ask for a written diagnosis before choosing.

✅ How to use this estimate

  • 1 If you are inside warranty with healthy SOH, treat the big ₹ number as a planning ceiling, not a bill you will pay.
  • 2 Buying used? Ask the seller for a battery health report and a written replacement quote from the authorised workshop — then paste the pack price into the override field.
  • 3 Use the monthly reserve only if you expect to keep the car past warranty and past ~70% SOH. Pack prices are falling, so over-saving is common.

Estimates only — not a dealer invoice. Chemistry rates, GST, labour and scrap credits vary by brand, city and year. Always verify with an authorised service centre for your VIN.
