EV battery health check with a written report
Find out exactly how much of your battery is left, in a number you can trust, before you buy a used EV or decide what to do about lost range. We read the state of health straight from the car, check the cells and the cooling system, and give you a written report. If the battery still falls under factory coverage, you will know that too.
EV battery health check
- Read the battery's state of health from the battery management system, not just the range guess on the dash
- Compare usable capacity now to the capacity the car left the factory with
- Check cell balance, so one weak group of cells is not dragging the whole pack down
- Inspect the battery cooling system, which matters more in Miami than almost anywhere
- Review fast-charging history where the car records it
- Check the factory battery warranty by VIN and tell you if the pack is still covered
- Give you a plain-language written report you can keep, or show a buyer or seller
Signs you need this
- Your range has dropped and you want to know if it is the battery or the heat
- You are buying a used EV and want a number before you pay
- You are selling and want proof the battery is healthy
- The range estimate jumps around or charging stops early
- A battery warning came on
We look up the factory battery warranty first, because if your pack is covered the manufacturer, not you, pays for it. The check itself has a written price before we plug in. Tax applies to parts only, and this job usually has none. Any repair that follows carries the warranty length you choose: 90 days, 1 year or 2 years.
