There's an interesting thought! I'll need to see what brands are 
supposed to be AAAAs, and if not, well, I need a spare PP3 for the 
multimeter.

[BTW, when did the world stop using PP3? all the batteries here have 
'LR' numbers, it's like they seem to want to phase out the older types - 
how stupid if that includes 'AA', 'C', etc]

[BTW2, just out of interest, was there ever a 'B' size cell?]

I don't recall seeing anything else...

The hardest PP3 I ever saw was the little plastic RS rechargeable. It's 
like it was embedded with the plastic poured around it, not those flimsy 
tin-foil-wrapped efforts you see nowadays with "Made in PRC" stamped on 
the bottom.


Thanks for the suggestion.


Best wishes,

Rick.
