From an electrician’s point of view, it’s a useless piece of kit. The batteries are measured without a load, so even when they are flat, the charge level may still show as 70%, for example. The measurement results are presented solely as a meaningless line graph.
No-load measurement
It does not display the voltage; it only shows a line graph
I would be satisfied with the product, except for this "detail": even with discharged, discarded batteries, it reports 70-80% and a "good" result. Although such a battery no longer works in the device (the flashlight doesn't light up, the button battery in the keys doesn't unlock, the pencil battery in the keyboard/mouse no longer works. ). So it is quite a significant flaw in the battery tester that the test result does not tell me anything about the real usability of the battery.
Looks good, solid construction.
Slots for all possible types of batteries.
The measurement result does not correspond to reality. Even dead batteries rate as 70% "good".
