Ratings and Reviews
Helped me sell my EV for more!
I recently used the ClearWatt app to aid the sale of my electric car, and its battery health feature made all the difference. ClearWatt specialises in measuring and certifying the performance of an EV’s battery, which is crucial for anyone buying or selling an electric car.
The app provides a detailed battery health report, showing metrics like capacity, efficiency, and overall performance. Once the test is complete, it generates a professional certificate that verifies how well the battery performs. This certificate was a game-changer for my sale. It gave potential buyers confidence in the condition of my car and set my listing apart from others on traditional platforms.
Using ClearWatt was straightforward. Running the battery health test took just a few minutes, and the app guided me through every step. The certificate not only added credibility but also allowed me to justify my asking price, which helped me secure a much better offer than I expected
Easy to use
Used this app to test my Kona and found the whole process to be very straightforward!! After I completed the test, they emailed a final report to me where the range data was spot on for my car. Would highly recommend for anyone looking to buy a used EV.
Brilliant!
I had a used Renault Zoe on test from a dealer who couldn’t tell me anything about the battery. This app really helped me understand what I was buying. Quick and easy to use and takes the mystery out of buying a second hand EV. Highly recommend.
