I am asking for a single device that can not only charge all common battery types, LiPo, LiHv, LiIon, LiFe, NiMh and NiCd. But also it can test them for capacity, health and faults automatically. Basically, you put any (rechargeable) battery insode and the device tells you if the battery is ok to use, what current and max capacity are, all while the battery gets charged.

If such a device does not exist, what would come closest?

I will spend around 4 weeks in far-north Scandinavia. I am wondering what I should take there. I am expecting freezing weather and little daytime. I will do some outside work, also in the snow, e.g. some builsing maintainance and cleaning snow.

I have not been that far north yet, so what kind of clotting should I bring specifically? Also, are there some general things I should consider?

Does anyone know of a mouse that can be used wireless, with a replaceable battery and that can be connected to the PC via USB-C to recharge the battery? Obtainable in Europe.

The reasoning is that I do not want to get into the situation where I do not have a charged replacement battery at hand and am therefore unable to use the mouse.

Currently I am using a mouse without a replaceable battery which got so old that the battery only holds for 1-2 hours without being connected to the cable.

I know I could simply go with a wired mouse, however, I like the cleanliness of minimal cables on my desk. Thanks for suggestions.
