I have a fairly expensive flash light. Unfortunately it now has three
corroded AA batteies, in the "power tube". That corrosion prevents
"easy" removal / replacement.

Might one have a suggestion as to how I might remove the corroded
batteries?

I presume the batteries are swollen, prevents removal.

You might try drilling the center of the batteries, making
progressively larger holes and then try to collapse the batteries so
you can pull them out.

I'd also try a solution of water / baking soda in the tube to cut some
of the corrosion. YMMV

If you know what make the batteries are, do you know if they are
supposedly "guaranteed leak-proof"? Many years ago I had a flashlight
replaced free when the supposedly leak-proof Ray-o-Vac batteries ruined it.

So *maybe* you don't need to get the old batteries out.

Sad to hear. Do you know the brand and type
of batteries? Alkalines remove differently
than carbon zincs.

I've sent back flash light with corroded
Duracell, and they sent me a debit card to
buy myself another light. (Note: Card only
works three times, and I lost the rest of
the balance.)

Rayovac had some leak (new in package) and
they sent me a load of high value coupons
(up to ten bucks, some fives, and some singles)
which I used to buy more batteries.

I'd admit, I'd not considered a carbonate
to remove alkaline. I might have tried
vinegar.

Lube it up as above and screw a small lag bolt in it. Tug it out.

Being ALKALINE batteries, a mixture of vinegar and hot water will
likely be more effective.

Doh! I've got car battery corrosion on the brain.

Have an old military flashlight that is copper inside the tube with a
minor corrosion spot. Because tomatoes are acidic I may try ketchup
(catsup) :-\

Thanks for the correction (Chirs too)

I assure you, the light is now shot...toss it.

If the corrosion isn't "too far" into the tube,
a plumbers fitting brush might help.

Or some sand screen, and your longest couple
fingers.

My turn, again. Eight D cells, Rayovac,
new in the package. Bunch of liquid and
crystaline white inside the package.
Best before Dec 14, still in date even.

If Rayovac batteries keep leaking, why do you keep buying them?

My experience is the "best used before date" means nothing.

These were purchased in 2008, and hadn't leaked in
the last batch of leakers. They did send me a bunch
of ROV coupons, so I got more. Which have not yet
been an issue.

Have you stopped beating your wife, yet?

I usually buy Duracell batteries, assume that is my noted situation.

If I can get the batteries out, is thaere a suggestion as to how I
might protect the battery tube, before putting in new batteries?

I really do not have a viable answer for you Rob.

Perhaps spray inside the tube with a clear lacquer spray?

Contacts are not like they used to be in military lights using copper
components in the tube.

I presume various metals are subject to different degrees of
corrosion.

Send it back to the battery manufacturer and they will either repair it or
send you a check for an equivalent model.

The big three do have warranties. I've used the
Duracell warranty twice. And had some Rayovac
leakers (not in lights). Both companies have
been good about the replacements.

Might one have a suggestion as to how I might remove the corroded

batteries?

1) screw an eye bolt in the tail of the last battery. use cord as DIY slide hammer to pull the last battery out. Hope that the other two aren't as stuck

2) remove both head and tail from battery tube, if possible, and use a dowel to knock the batteries out of the tube

for cleanup I have found that after flushing with water, Deoxit will get most of the nastiness out. If you need mechanical cleaning some scotchbrite (rip off small squares and push through with dowel etc.) may help. I'd definitely spray down with deoxit after finishing. Maybe even Boeshield T-9 or similar if this is a "hard use" light but only on the battery tube not on electronics (if any - I'm assuming that this is a modern LED light or you wouldn't be going through the trouble.)

Grease the threads and O-rings with Super Lube, Sil-Glyde, something like that.

and ditch the alkalines! Energizer Lithiums for primaries, or LSD NiMH for rechargeables (Sanyo Eneloop, Duracell Ion Core (which are supposedly rebranded Eneloop XX for an excellent price, and readily available in stores now), Maha Imedion, Tenergy Centura, etc.) Otherwise this will just happen again...

If the cells are well and truly stuck, if you can determine or already know what brand they are (and it's a major brand), contact the cell manufacturer, they may buy you a new light.
