A completely dead 1.5V button battery showed up as "good" with all bars on the meter. So I put it in the slot for 3V batteries. There it showed as weak - apparently at about 50%. So the tester is completely useless.
Even completely flat batteries are "good"

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’ve had it for a while now, so hopefully it’ll do what it’s supposed to.

For some batteries, the evaluation is biased.
