I think so.
The service life of a battery is foreseeable and then what?
What type is it, can you get it anywhere, can you replace it without problems...
Or will it say in 3 years sorry, this battery doesn't exist (anymore), be creative or buy something new.
I think the topic is definitely relevant.
When the button cell in my Mastech tweezers is empty, I buy a new one from the store around the corner and that's it.
It's a standard type that has been around for decades and will be around for decades.

Completely agree with you about battery powered things :-+
I just wanted to give my feedback about the superb Shannon support, as I was having a hardware problem.
=>He helps me a lot (with PM here) to fix my ST42, with some pieces of shematics.
And when I found the problem: he send me the chip, and also the back cover - all for free (because my iron solder has slipped when I tried to remove the dead chip, and I have made a little hole inside this back cover...).
(if you want to check, was in previous page on the topic here: https://www.eevblog.com/forum/testgear/design-a-new-precision-lcr-tweezers/msg5349764/#msg5349764 )
I have not find any companies doing this.
The other serious one I have found is RD-Tech (PSU RD6006P and all great USB Meter I have), but they have not gave me the little capacitor to fix the overshoot fault I have found for free...(here if you want to check: https://www.eevblog.com/forum/testgear/ruideng-riden-rd6006-dc-power-supply/msg4354561/#msg4354561)
So, I think we have not to be worried with @Shannon support :-+ That's what I have tried to explain ;)

I´m quite sure that LiPo-pouches already are that ubiquitous that you will be able to buy most of the sizes in near future or slightly smaller ones with the same capacity.

Hi
Rob of Tautech sold me a set of Shannon ST42 smd tweezers.
Up to now I have got by with a cheap Chinese component tester, but they are hopeless for smd work. I rarely use thru hole components these days and using multi-meter sized probes is harder than it should be.
The ST42 is definitely not bench meter accurate, but I don't need that. It has a good display and a lot of functionality packed into a very small space.
I designed and printed a 3D stand based on the Gridfinity storage system I have adopted. It can now stay on the bench where it is easily accessed while being protected.
The stand holds the test board. The case and spare parts stay in the case.

I've found it to be quite competitive even with very high-end bench meters. If you have a question about accuracy, make sure to do your open/short corrections first. Also make sure you're on the latest firmware.
See attached.

Dazz, pop this message into the ST42 thread and Shannon may choose to add it to a POI list.
