Was asked to look at some re-chargeable cordless headphones a pal has which needed new batteries.
Standard AAA cell - but the housing was different to normal, the negative contact, which went to the side, rather than bottom, of the cell. The originals having the sleeve cut off short to allow this.
And I've no idea why - apart to make it more difficult for user replacement. Unless to prevent using alkaline?
Shaves a few millimetres off the length of the battery compartment so the overall?
PS IMLE a "cap" of kitchen foil can be an alternative to shaving the side of the battery - especially when just lending someone batteries!
My mother had something like that @30 years ago, most of her stuff was Panasonic and probably it was a portable CD player.
Memory is rusty but the original rechargeable batteries had the side contact but if they were discharged ordinary primary cells could be used with no chance of the user trying to charge them by mistake as the charging was done inside the player. Now you could also use externally charged rechargeable instead of primaries but they were not very common for the ordinary consumer then.

Oh yes - I'd forgotten about in-device charging and guarding against consumers trying to charge Alkaline.
Well not std then, Panasonic had them as a HHR-4AH
Since my other post I got curious and see they are sill obtainable just if this supplier really does have them
if you want to replace the originals as is.

Fush moi. 5 quid a cell for AAAs. ;-) See why now they did this.
Removing the bottom part of the sleeve from Lidl ones has done the job.
