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

About to sell my EV and acutely aware of how nervous buyers can be - especially about battery health. I knew my battery was in good condition as I had looked after it for several years and still got great range from it. But how do you convince a buyer that you’re not just exaggerating? The answer, let this app monitor your EV efficiency over a few drives and get a thorough report. As the app relies on a good mobile signal to monitor all sorts of things that would effect the result (terrain/speed/weather etc), I had an issue with two of my drives being over the North Yorkshire Moors and the signal had dropped and so the drive couldn’t count. However, the support at Clearwatt was first-class. Same day responses and very helpful advice. Overall, a great app and customer service. Highly recommended.

Just used ClearWatt for the first time on a 4yr old MINI Electric in pretty cold weather (-4 to +6 C).You need to record 3 x 11+ mile (18km) journeys which takes a bit of time.You get your report after the paywall at the end of the data collection.The app is really easy to use.My app got stuck ‘processing’ after the 3rd journey which was rectified very quickly on using the ‘report problem’ within the app.Delighted with the pdf output: clear, helpful, informative - and invaluable for any potential 2nd hand EV buyer… especially if you get the A+ rating!

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.
