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 ...
