I have the LCD one, which is handy for a quick "Does this battery go in the bin, or in the 'Use again' box?" - marginally less hassle than getting a multimeter and a load resistor together. Neither input will give me a reading from 3V lithium cells, tho', which is a minor annoyance (I guess 3V trips the boost regulator 'overvolt' status, and isn't enough for direct drive).
I've never regularly used one of these testers before this, but was surprised at how quick and convenient it was to go through a whole collection of batteries .
Thank you. I had a detached wire and this showed me where it attatches to the circuit board.
Glad it helped
Excellent review and teardown, thanks Martyn. I have the analogue version in the workshop but could do with an extra one for the house.
I like the simplicity of the analogue version. It only took a few minutes to go through a drawer of batteries and quickly identify the dead ones.

Can you add a load to a lcd one, so that it actually loads the battery?
There is not much in there, just a meter and load resistor
Where have you been?
Just busy with other stuff, including moving house.
