I'ma go with up a rectum. Shouldn't matter whose. Just sounds like a safe place.
Well I think it does matter who, some folk seem to have intruders back there![]()
No that's too much of a mouthful.
It's just a li-ion 3.7v 1700mAh 6.29Wh rechargable
Same as lipo then - 3.85v (around 40% charge) and somewhere cold (but not freezing).
They don't self discharge, so no need to charge them up every now and then like you have to do with nimh chemistry.
