Default Alkaline batteries still working fine in the cold

Is it just rechargeables (Nicd and NiMH) that aren't supposed to like
cold temperatures?

We have a WH1090 weather station in the garden, powered by two AA
alkalines ( Costco /Kirklands ie nothing special) , and it worked fine
at the lowest we've seen so far; -11.4C.

According to the specs it can go down to -40 but I don't think any
batteries would like that.

Probably fine in a low drain device but I know of divers who have had
problems with alkalines in high drain devices (like big torches) in cold
waters.

We too have some external wireless thermometers - they have always
worked so far as I am aware. But if the batteries are towards the old
end, the cold weather might force replacement.

Energizer Ultimate Lithium are supposed to operate down to -40.[1]

[1] Please don't point out that I have not put C or F after that. :-)

Batterues don't just stop working at a certian temp - the internal resistance goes up, so
higher-load devices will notice problems long before light-load things like weather stations.

Well, it is unlikely to be Kelvin, but it could be Raumur, Rankine,
Rmer, Newton, or Delisle.

-40C = -40F = 233.15 K = -32R = 419.67Ra = -28.5R = -13.2N =
-210De

And -13.5R - teaches me to try and do it all in my head. I'm out of
practice.

As have I and mine is still on its original cells. I think it is
current delivery (rather than voltage) which mostly affected by the
cold weather and these do not draw very much current.

My CH programmer was lying in the living room today while the windows
were out as I was getting new windows fitted and when i eventually
found as they were clearing up the LO warning message was showing (
room temp 5 deg C) but as it warmed up it went back to normal..The 2
batteries are Energizer Lithium AA's

Thanks for that. I inherited a dual- display wall thermometer some
years ago which is calibrated in centigrade and Raumur. Always
wondered what that was about.
