Sistema 400ml product dimensions from Amazon: 11.51 x 8.99 x 16.99 cm (17cm seems like it might be wrong measurement) an AA battery is about 5cm x 1.5cm x 1.5cm I have Really Useful Boxes 0.7 litres for storing batteries You can fit at least 40 AA batteries in them. This Sistema container is only 0.4 litre, so I would guess less than 20 (plus the Sistema box seems to have curved internal corners). Maybe I'll stick with the RUB for this case use :)
You most definitely wont...
You will get 34 AA batteries in one no problem.
They are indeed. It does state the size on the title (400ml), I'd say they can still be used for lunch bits like fruit, portion of coleslaw, yoghurt, biscuits etc. Handy for their intended use however for a full lunch you'll need much bigger.
Nearly bought these until I checked the ones I already have. They are 1 litre. These are tiny!
