I guess I should not assume but I saw these on ebay when looking. They are made in Germany but they might have been made a few years ago. Perhaps they have since moved to manufacturing in China? MAHR FEDERAL 16EX DIGITAL CALIPER | eBay Simon
Girl, I don't wanna know about your mild-mannered alter ego or anything like that." I mean, you tell me you're, uh, super-mega-ultra-lightning babe? That's all right with me. I'm good. I'm good.

Just on the score of storing spare batteries: I read or reasoned many years ago that keeping them frozen retards the chemical reaction and therefore (at least some of) the discharge. Have been storing them frozen for the last 30 years (err, not the same ones) and certainly haven't noticed any problems. Whether or not the life is extended I couldn't say, as I've not done any comparisons. They have to be wrapped in plastic and/or put in ziplock bags to keep out moisture.

Bret that tails goes back to the old Dolphin batteries when I first learnt of it a boss made us throw them into the fridge or grab new ones bought as a lot.
Gents I thank you all for the comments ideas and suggestions I do appreciate it all and shall come back and re-read quit a bit of it as re-the batteries its all very interesting as much as that info on vernier differences and possible inaccuracies of many mentioned. Good to see how so many have taken the time to do the testing involved to assess them.

Snopes has responses from Duracell and Eveready about batteries in fridges

Well there you go, I can save a wee bit of electrickery. Now I just have to find another place to store them.

Hmmmmm.
From said Eveready response:
"Alkaline and carbon zinc batteries contain a water based electrolyte. As the battery temperature approaches the freezing point of water (32°F or 0°C) chemical reactions within the battery slow down due to reduced ion mobility. Ion mobility defines the ability of electrons to freely move, critical to the generation of electricity through a chemical reaction."
Surely that would appear to back up my logic
As far as this is concerned:
"Cold temperature storage can in fact harm batteries if condensation results in corroded contacts or label or seal damage due to extreme temperature storage."
I've never had a problem with malfunctions/leaking/corrosion after freezing. They just have to be put in your pocket for a while before use.
