“The reason for choosing the 4-4-2 from Dokter Accu is that I wanted a good and user-friendly battery tester in the workshop that is easy to operate and gives a clear picture of the battery to be tested. I also thought it was important that the tester can print out all the data in a clear overview. The 4-4-2 met all these requirements. My experience with the 4-4-2 battery tester is that it is user-friendly and that it is easy to connect to the battery. You can then immediately read the values ​​of the battery in the display. We have already tested various batteries of bicycles to be traded in and were able to show the customer the condition of the battery. Then you can make an informed trade-in price. I would choose Dokter Accu again in a heartbeat because a lot of attention is paid to explaining how it works and there is also sufficient feedback from the company.”

“When purchasing a battery tester, I paid attention to three things: price, ease of use and voltage choice. Every tester on the market has its pros and cons. Some testers are too simple and therefore somewhat limited, while other testers are very extensive and sometimes overcomplicate things. The 4-4-2 is just right in terms of possibilities and ease of use and that is also the reason that we use this tester by far the most and often. You can easily choose the right voltage (24, 36, 48 Volt) and with the push of a button a peak current can easily be set temporarily to simulate a significant resistance. That, together with being able to quickly start the actual test, makes it the go-to tester for us. The times we choose another tester are rare specific cases where we need additional parameters or variables. I would therefore choose Dokter Accu again. The ease of use is decisive; we just need far fewer actions to do a test. We test on average about 15 batteries a day and use 8 different testers for this. Almost never all 8 testers are on at the same time, but when we are testing, there is always a 4-4-2 on.”

A special customer of Dokter Accu is Bpost. The Belgian post has a total of more than 2000 e-bikes in use and uses 65 battery testers from Dokter Accu (model C) at the regional distribution centers. “The need for battery testers was very great for us, especially before destroying old batteries,” the company reports about the choice for the 4-4-2. “In the search for the right battery tester, the 4-4-2 came out on top in terms of price and ease of use. Our experiences have been positive: the testers are easy to use and the software works well and provides complete and reliable information.”
