And IoS 7 will make your iphone waterproof
that sort of thing would only be done on fake batteries , speaking of which when rechargables first appeared the C and D cells were hollow with a small stubby cell not that much bigger than an AA inside them.
moral - look at the mAH rating or buy rechargables by weight. Not really a problem nowadays, but you do get the odd pack of cheap rechargables that are only half rated.
Notes on battery chemistry
Batteries for long term storage should be charged to 40%.
(NiCAD don't mind, lead acid full charge is better )
Lithium (laptops, phones) and Lead Acid (car , alarms, ups) batteries die forever if you let them go totally flat. I think the same is true of rechargable alkaline but they are rare. So if you leave batteries check up on them every so often.
Lithium has twice the storage capacity of NiMH by weight , by volume it's about the same.
NiCAD batteries are ok with being flat. Actually it's better to let them go totally flat than forceably deep discharge them because what kills all batteries is when one of the cells goes flat and the others keep pulling current through it.0 -

You've not used Irish public transport have you?
I've lived in Syney five years now. They were standard on trains when I got here. I thought they might have been on new Irish trains by now, if not at least on the lives of London, Paris and other cities with proper rail networks. Guess not.

Possibly.
Note that this should work with most types of cooking oil.
And possibly Duckhams Hypergrade (but definitely not Magnatec - it will stick to the pan, rendering your non-stick pan completely and utterly sticky)

I'm guessing it's gas making the battery swell or volumatic changes with chemicals. But would depend on the composition of the battery.I don't have any batteries at hand to test this but it looks kinda cool
this is more fun
