I've had several batches of AA/AAA batteries from LiDL and found them
OK, some of my oldest ones not holding so much charge now, so noticed
them on the shelves today and picked up so AAs, got them home and they
felt suspiciously light ...

So I've weighed pairs of various AAs I'd had over the years, in roughly
chronological order, some are well past-it and only used in last resort.

Ansmann 2200mAh NIMH 57g
Hahnel 2350mAh NIMH 58g
Sony 2000mAh NIMH/LSD 52g
Maplin 2100mAh NIMH/LSD 56g
LiDL "red" 2100mAh NIMH/LSD 55g
LiDL "black" 2100mAh NIMH/LSD 53g
LiDL "silver" 2400mAh NIMH/LSD 37g

I'm somewhat suspicious that the latest LiDL/TRONIC batteries are *so*
much lighter, yet claim to have higher capacity ...

Are those weights for pairs? I've just weighed some Eneloops:
2.4Ah 30g
1.9Ah 26g and
Lidl from a few years ago 26g.

The 2.4Ah ones will run the toothbrush for 5 weeks.

Back in the old days of ni cads, it was common for the same cell sizes to
just be put into the bigger bateries. Tandy used to do this a lot. their
later ones managed to make aa batteries more powerful, and hence the C sizes
got lighter for the same size/capacity. More space inside one supposes.
also some of the berec hi power ones had vents and did lose weight over
time as one supposes the elatrolyte boiled off to some extent.

I'd have though somebody might have this documented somewhere.
the newer technologies seemed to change some years ago when te auto
discharge rates suddenly stopped being a factor which effectively gave the
same batteries more power.

Difference in case construction possibly ?

I've peeled the foil wrapper off one, they are a full metal canister,
but thin enough material that you can *just* feel it deform if you
squeeze it between finger and thumb ...

The pre-charged ones (low leakage) have a different construction to the
old ones. I have no idea if it makes them lighter as I have never looked
into it.

I weighed a mixture of LSD ones and standard NiMH, before now only the
Sony LSDs were lighter, and not by anywhere near so much.

Comparing LiDL's LSD types, the newest AA (18g) feel closer in the hand
to the previous AAA (13g) than the previous AA (27g).

Seems they only hold about half their rated charge ...

Is there a standard for measuring capacity, or is it a case of 'peak
music power'?

Some of the 'intelligent' chargers will measure capacity, they run the
cell down, then recharge it, e.g.

https://youtu.be/IA-MZZD7HEQ?t=11s

As that's on older video it think it's not the v2.2 firmware which
altered the fan behaviour, but that chap seems to do reasonable
multi-meter reviews and it's not in Russian which half of the youtube
reviews seem to be.

Of course various factors such as the charge rate, discharge rate,
whether they measure on the way in or way out etc result in different
numbers, this site shows charge/discharge graphs
