Useless!
This Battery Tester seems just to measure no-load Voltage. Unfortunately, Voltage isn't a good measure of State of Charge - the Voltage doesn't drop off significantly until a battery is completely flat.
So .. the Tester says that Batteries are 'Good' until they are absolutely as-dead-as-a-Dodo, when it finally admits they're Flat.

Not really a very useful battery tester ...
Batteries which are virtually flat, and certainly no use for your camera or any other device still tend to produce a result in the green area of the scale on this tester.

Once flat they then edge into the yellow part of the indicator scale.

Hence, battteries in the full range from fully charged to nearly flat tend to return a result somewhere within the green part of the scale - which is about 5mm wide. It's just not useful in helping you to assess which of your batteries are charged and which need charging.

I am now looking for something better to replace this tester ...

don't bother
This tester just measures the same voltage all the time, batteries are always in the green even if they are dead, Maplin do a good battery tester for under £10 i would go with that!
