Well, you'll need to drill through additional holes. Edit: However, it has exceeded me and everything is ok 
It just looks like the hole spacing in the new version is about 3mm wider in the vertical and by applying the plate to the casing looked like the holes did not overlap.
4- the bottom of the housing is good to stick with 4 pieces of soft plastic, because the fixing screws can scratch the delicate table tops. Well, I gave "bodies", I did not read about the film.

I also do not understand the need for instructions, all in all it is necessary to appreciate the fun-puzzle and saving forests

I use these cells as an alternative to disposable links in portable devices (such as radio). I would just give 2x18650. As the voltage will stick, it will trigger a warning. The most economical option. At nominal 3.6V it will be 7.2V and for a full 4.2V it will be 8.4V. It fits nicely in the 9V battery voltage risk. And the capacity around 1000mAh should be enough.You know, from waste, I would not count on having nominal capacity. And soldering, the use of cables, or even time would have to be counted.

What do you replace such a battery with? I'm asking out of curiosity. Because I'm the Sunday "electronics" so I'm not a reference point. I would rather buy batteries for a dozen or so PLN than to combine with inverters.
TL;DR: LCR-T4 auto-tests 14 part types, draws only 12-15 mA per measurement, and “will be useful in every workshop” [Elektroda, TechEkspert, post #16556695] Accuracy stays within ±2 % for most resistors. Firmware flashing adds live-scan mode and Zener tests. Why it matters: you get multimeter-level insight from a €10 gadget.
