How it works

  1. 1

    Enter your vehicle & situation

    Make, model, mileage, and what you're seeing — range loss, a warning light, a repair quote.

  2. 2

    Add a quote or value (optional)

    If you have a battery quote, we compare it against your car's value — the number that decides most cases.

  3. 3

    Get a decision, not a shrug

    A clear recommendation with the economics laid out, plus the exact questions to ask a shop.

An EV battery decision, not a guess

A battery repair or replacement can cost anywhere from a modest electrical fix to a five-figure pack. The right call depends on the quote, the car's value, how much range you've lost, and whether a warranty still applies. This calculator puts those numbers side by side and gives you a clear recommendation.

It works for EV and hybrid owners anywhere in the U.S. — no account, no email required to get your result. Buying a used EV? There's a mode for battery due diligence too.

What this is — and isn't

  • A decision-support tool: repair vs. replace economics
  • Quote-vs-value analysis and questions to ask a shop
  • Not a high-voltage battery diagnosis
  • Not a guaranteed repair price
