Review on Car battery tester digital KONNWEI KW650 by Adam Pietras ᠌

In general, this is the case. On December 4, 21, after reading the laudatory OD about the wonderful properties of the KONNWEI KW 650, I decided to purchase it. Although I myself already had a cheap tester from another manufacturer in use. But how, I wanted to "grow", to have a more expensive and high-quality device. But no. Didn't guess. Not everything good is expensive. After a series of measurements of batteries, I noticed one feature, when KONNWEI repeatedly measures the same battery, it shows different values. It got to the point that the values ​​​​exceeded the face value twice. That is, a 650A battery, gave out a value of 1156 EN. And such problems are not only with my device. So, the device is sent back.
