The battery manufacturers advertise sealed batteries. But they all have a hole in them somewhere. Flip a "sealed" battery upside down and see what dribbles out.

I did my research--before I placed extra batteries under by bunk---
new technology Bob: Silver-cadmium batteries were developed FIRST for use by Nasa--- they had a problem--Satallites in orbit were for some reason--getting slighly out of position.. It was discovered:::
As Creek Jackson pointed out above----lead/acid batteries give off--hydrogen gas---this gas was acting as a propellent in space.
Silver-Cadmium batteries use no lead in them--and produce NO HCL gas--
thus require no venting-
Do some research yourself.
also Google "adding tap water to batteries" will result in finding
that this practice ---shortens the life span of a battery--
you either use "distilled water" or you add New electrolite---they sell it at AutoZone.
@creek Jackson---I can turn my Sealed Wet Silver-Cadmium Heavy Duty Truck Battery purchased from Peterbuilt $89.00 several year ago----upside
down or any end---nothing comes out--and the label wore off years ago...no holes now how is this possible?
You have to take University Chemistry -----
lead-acid battery:
contains sulfric acid & water--- which is what makes up the electrolite
they are vented because they gas which is correct.
the flaw in What Happens to the "water level" is the problem.
It doesn't evaporate-----the O atoms ionize to the lead plate--
which then leaves the H2-free as a gas atom= hyrogen gas!
________________________________________________
silver cadmium battery doesn't have lead plates-
the O atoms don't ionize to them---no gas discharge-- hence no venting needed.

back to the lead-acid battery:
tap water???
contains????
usually--clorine
now when you add tap water to a battery:
you introduce a new gas discharge along with the explosive Hydrogen gas
you also discharge clorine gas
SEE: WWI( clorine gas is also called Mustard Gas and killed many soldiers during WWI
__________________________________________________ ________
Submarines Use Batteries
Submarines carry people that don't want to be gassed with mustard gas.
The Navy never used Tap water in it's batteries-wonder why?
___________________________________________
During WWI & WWII--subs had to surface to vent the hydrogen gas.
When the Navy head about Nasa's little problem with Orbital wobble--caused by gas discharged from the batteries---and that the Brains
at Nasa were now going to try to Engineer a solution----
they said---Hey, we sure could use whatever you come up with too
Now Subs can stay down longer.
