Very interesting idea.

Apparently:
"...The maximum rate of formation is 0.42 L of hydrogen and 0.21 L of oxygen per ampere-hour a overcharge at standard temperature and pressure..."

It seems most batteries are charged at around 5 amps.
So a MAX of around 2.1 Liters of H and 1.05L of O per hour, or nigh on bugger-all!
But because doing this is so easy, light and cheap; whyTH not!? Every bit helps! Waste not want not n all that.
(As voltage per cell is above 2.075V per cell, a lot of the Oxygen should be Ozone molecules which helps too.

If you have an old engine with a distributor as I have; piping the O3 from it into the intake too should also help a bit)
I'm thinking a deep, thin bubbler is a good idea:
It will need checking and filling less often and should get more of any acid fumes/mist dissolved into the bubbler water better.
I don't see evaporation losses in the bubbler being much an issue however as any gas from the battery should be pretty much saturated with water etc vapor.
As the water ends up with a tiny bit of battery acid in it; one might use battery water in the bubbler and then use that to top up the battery before topping up the bubbler.
