I've never tried it, but I hope someone has! Had a student who claimed
that vigorously shaking a weak battery would revive it to where it would
then give dependable service for a "length" of time. Realizing how it could
possibly allow for renewed chemical reaction to occur, it 'sorta' makes
sense, at least from a theoretical standpoint. But in practice? If it'd
work, maybe a paint shaker at Lowe's........?
Not arguing either way, I'm curious if anyone has ever tried it. s

I can see where shaking a weak battery COULD affect it if there was
stratification in the electrolyte, but whether or not you could even
detect the difference let alone make practical use of it is another
matter. As to giving 'dependable service' afterwards, I think the
student is fertilizing things.

Now, if the student disconnected it, or even if not, just moving things
around COULD cause a bad battery terminal to make connection,
and then work. Years ago one of the tricks of the trade was to use
a nail and hammer it in the 'gap' on the battery clamp. Nothing
magical. Just that when it worked it was because the battery connection
was so bad than disturbing it would make a better connection that what
was originally there.

Have you ever seen the top blow off the battery? You don't want to be
shaking it when it does. If it is bad replace it.

Sure give it a good shake get the Hydrogen gas moving one little spark and
your blind ( top blows off spraying acid all over, Best thing for you to
do is give your head an shake and don't listen to Idiots.

I havent tried it, and wont, BUT there is some basis for this.
This is what I have been told. Often sludge builds up in batteries and
gives a
resistive path between cells, essentially shorting them out. If you shake
the
battery and disrupt the sludge bridge, the battery may show better activity.

As I say, I have never done it, and wont. If a battery is gone, I buy a new
one.

I have a small vibrating table that I use in relation to gold panning
and I've considered putting a "bad" battery on it to see if it made a
difference. Maybe I'll give it a try when I have time. The table is
just a wooden frame with a flat metal platform on top with a 3/4 inch
lip along the outer edge and a vibrator unit from a vibrating "LazyBoy"
style chair. Don't know if it will work on a battery, but it does help
settle heavy material out of sand.

If one look at how auto batteries are constructed, they would realize one
would be more likely to short it out, than to rejuvenate it, by shaking one.

If the terminals are filthy with corrosion, the maybe shaking it to get the
corrosion off may 'revive' the battery. :-) But it'd be more
convenient to use a wire brush to clean the terminals, cables.

Will shaking a dead person revive it?...No I don't think so...a dead person
....a dead battery..they are all the same. Though some people have claimed to
have been revived from the dead using medical equipment...perhaps taking a
dead battery to a hospital will increase the batteries chances of being
revived also. Let me know how it turns out. Its an interesting subject
indeed.
