I got 7 years out of a generic battery, and it was still going strong.

I would be surprised if most outfits (service stations included)
claiming to dispense "distilled" water aren't pouring it out of their
mains taps. As with "genuine spring" water in supermarkets...

Distilled water is only as good as the distiller (still). Generally
for pure water several goes is necessary to get all impurities out.
And DON'T bother with this stuff for drinking, as it lacks necessary
trace elements and tastes AWFUL.

I've never bothered to look for distilled water.

Reverse osmosis? Osmosis is osmosis; there's no such thing as reverse
osmosis! It's merely the transfer of elements in a solution across a
semipermeable membrane, moving from an area of higher concentration
to one of lower, until the two balance (reach equilibrium). Whichever
way the elements/chemicals move, it's just plain ol' osmosis. Smells
of the idea of "deceleration" which is actually acceleration.
