add water to sealed car batteries
miste...@yahoo.com
pried open the top plate which covers the cells (with a screwdriver)
and squirted water into the cells. I then glued back the top plate.
The battery works fine now.
Anybody tried an easier way - like drilling a 1/4" or 3/8" hole into
the top plate into each of the cells- filling them with water, then
sealing the holes with clay or polyethylene plugs?

batteries usually one top up in their life will do it unless you
alternator has gone nuts and is then boiling them dry.
Those 'maintenance free' batteries are a bad planned obsolescence scam.
They lose water just like any other battery, just a little slower.
I got a 'new' Jeep the other day that 'needed' a battery. All it needed
was a little water in each cell and a nice slow charge. It now tests
out just fine.

Time to get up to speed everybody. If you can easily pry the top off,
you probably can add distilled water. However, many of the new
batteries do not use FREE water inside. They use a gel or a pad. Trying
to add water is playing with danger and yourself.

I have one of those spiral cell Optima batteries in one Jeep. There is
no free liquid in them but they are still a lead acid battery. When
they get a dry cell, they are garbage. No place to pry open either.

shade-tree mechanic told me one time when you have the battery out of
the car it
is a good idea to invert it, and let the "sediment" flow across the
plates on their way to the top which is on the bottom momentarily.
Also this type battery has small escape holes under the end's "eaves"
and have to be covered while the battery is inverted.
I've never had to add water, but see nothing wrong with it, and
especially tapping a hole in the top, using a plastic plug for sealing.

battery beneath the plates. On conventional lead-acid batteries, the
lead drops off the plates and falls to the bottom of the battery
whenever you charge and discharge your battery. Over the years, this
can add up to quite a bit of lead. When you turn a battery upside down,
all that lead falls between the plates and has a good potential to
short out a cell in your battery.
Anyway, the best advice is not to do it.

My grand mother had something like that, except that it was a
glass globe with a country scene inside with a horse drawn
sleigh, if you turned it over, it made the inside look like snow
was falling.

Wow, the house my grand mother grew up in had escape holes also.

If [you're] going to the bother of 'tapping" a hole, should he
use a threaded plug?

someone.....
And by the by, a battery needs to be vented. If you drill out the vent
and block it you will have issues. Maybe explosive issues when the
hydrogen gas builds up and has no place to go....

Exactly. A lot of drag or street racers would put the battery in the
trunk for a weight transfer advantage. Except instead of one battery,
they might put two of them in it. And they might be big ones from a Cat
dozer. The back seat would be taken out (to save weight) and a sheet of
metal would take it's place, all neatly sealing up the trunk area. Then
they would wonder why the trunk lid would blow off.
Bottom line: you need to let the gases escape.

Just make sure it's fresh water.
Salt in battery may bring up a wrest in tainted cells.
This is a well-known current event, even as charged.
Although I realize that my posts, many may diss, still.
Water we wading for? My discharge?
