Well sure, that's essentially what bottled water is anyways.

Distilled is hardly the same as filtered (which is actually what bottled
water typically is).

Most bottled water is dead water. You couldn't find a mineral in there
to save your life.

It is your battery, use what ever water you want. But most
bottled water has minerals added so there is a flavor, some
waters now have flavors.

Only distilled water is pure, deionized water is OK too, but
that is harder to find on the store shelves.

Just an update: mechanic put the charger on the battery this a.m. He
said after an hour, it was bubbling all over the place. It is toast.
Looking for the comparable RG replacement right now. Oh well, learned a
lot, anyway. Thanks to all here for responding.

Aircraft batteries should be charged on a constant amperage
of about 2 amps and the voltage should be less than 14.5
volts. Standard automotive chargers will fry an aircraft
battery.

Why? How is a 6 cell lead-acid aircraft battery different from an
automobile battery, other than having less capacity obviously.

An amperage selectable one should not. A popular charger configuration out
there, is something like 2 - 10 - 50 amp chargerm and that should only be
putting out about 14.4 volts.

So? Even if more than half the bottled waters out there have had every
molecule of minerals filtered out (and I doubt that's true), that doesn't
make the water distilled.

Bottled water is filtered tap water and often is enhanced
with "minerals for taste" or spring water which also has
minerals.

Distilled water has been BOILED and the steam condensed, it
is as pure as chemically possible. Less than a dollar a
gallon. A gallon will keep the battery in your car and
plane filled for about 25 years. Use a basting syringe to
add distilled water, an ounce at a time, six cells. If the
electrolyte level is low in all cells that means that it is
working evenly, but if just one or two cells are low, there
is likely to be a problem developing.

FAR preventative maintenance does allow the pilot to check
electrolyte levels and add water, also use a hydrometer to
check specific gravity to see that the battery is fully
charging. That combined with a voltage check to be sure
that the system is not charging at too high a voltage is the
most important things a pilot/owner can do to get maximum
life.

But all batteries wear out because lead flakes off the
plates and collects in the bottom of a standard lead/acid
battery [that's why the plates do not extend all the way to
the bottom of the case, the space is there to collect lead
sludge. When the sludge touches the plates they short out
and the cell is dead.]
