I assume you fully removed the tubing from the rest of the light?

Id first rinse out any crystals, then use a dilute white vinegar mixture with a small scrub brush to get most of the junk out, then chase with a dilute baking soda mixture to chase acid. Then rinse again, and test fit batteries. If the don't fit, I'd force a sanding sponge or a dowel with fine sandpaper wrapped around it, to smooth/remove material.

Once that's done and the batteries fit, Id do a final wipedown with something like crc 3-36, put batteries back in, and call it a day.

Takes D cell batteries = obsolete

The lights themselves are OK for a budget light. The battery source is terrible. D batteries leak terribly, and you should not store a D battery in anything that you care about. Ideally, any item that takes D batteries should be stored empty while not in use. An 18650 battery can be recharged hundreds of times, and for the most part, dont leak.

In 1985, a Maglite was a quality option. Today... not so much. You get a much better light for the same money from someone else.


Yet when a chinesium 18650 goes up, in a minimally enclosed charger, the results can be disasterous, far beyond anything a leaking alkaline can do.

I have not yet read all of the replies, so excuse me if I repeat information from others.

I had the exact same thing happen to my Maglite 3-D cell flashlight. I had to drive a long drywall screw into one of the batteries, grab the screw with a long nose vice grips, and pry the battery out. It was really stuck in there.

Once removed, the inner body of the light was corroded and the new batteries would not fit in any more. I used a long philips head screwdriver with a handle that was just slightly smaller than the inside of the flashlight, wrapped the handle with emery cloth taping the starting edge to the handle, chucked it up in a cordless drill and spun it until the bulk of the corrosion was gone. Cleaned it out with compressed air and put in new batteries. Worked pretty well.

Hope this helps.

Isn't that odd. I had a battery corrode in my Mini Maglite. That's 3 of us. Never had it happen before either.

I got it going again as a matter of principle - even though it's not a great flashlight. I keep it on my bedside table. It would be a good thing to have if there's ever an earthquake at night (we're in a high risk area) and the power is out - which it probably will be.

For me it was a matter of getting the corroded battery out (which was not easy), then cleaning up the contacts. I partially drilled it out which left a burr on the side of the central tube which I polished out with emery cloth. It works as good as new again - not very well.

That's four of us now!

I'm starting to wonder if there's a problem with Maglites.

The corrosion is way down right next to the light bulb assembly. Been a good light and just updated it to the LED set up, sure would hate to have to trash it.


Do you know what brand battery? if a name brand follow their warranty instructions and they send a check for the cost of a replacement Mag-Lite and you can stop wasting time attempting to fix a destroyed unit and listening to lectures about your poor choice of flashlights.
Coffee

Other alternative, is shipping back to Maglite warranty center with a note explaining you tossed the batteries out, or whatever. They will probably send you a new 3D mag-lite just for the sake of good customer relations. Cost $7 in a USPS flat rate padded envelope. Not a bad deal $30 flashlight for $7.

I sent Mag-lite a well worn 3D few months ago, they totally rebuilt it no questions asked.

It looks like [censored] now, but still works great.

I agree that D cells are simply alkaline batteries and certainly nothing exotic, but to say that they're obsolete is just ridiculous. Like any alkaline battery, don't leave them in something for extended lengths of time if you're not going to use the device regularly. This isn't rocket science.

Are there better flashlights out there? Absolutely. As I mentioned earlier, a 3 D cell Maglite is only about $35. Don't expect to get a hundred dollar light with the old style Maglite. Maglites are very simple technology, and not very sexy in today's environment where the market is flooded with tacticool lights. That doesn't mean they're garbage though.
+1 THose who claim a Maglight is "junk" without further explanation will try to go 15K on a cheap filter and brag
about it. Personally, a 2 AA cell Maglight with an LED bulb is a fine flashlight, and it's NOT made in China.

Yes I can't tell you how many bad batteries I've seen for sale online. I try to steer people mostly towards the Panasonic based protected cells which are available if you know what you're buying.

The popular ones are Panasonic NCR18650B.

Here's a decent brand. https://www.orbtronic.com/protected-3400mah-18650-li-ion-battery-panasonic-ncr18650B-orbtronic

I'm also pretty happy with my nitecore charger even though I still have a Pila IBC I no longer use.

As with anything, you buy cheap Chinese junk, you face the consequences.

Sticking with well known brands and retailers should help greatly minimize the issue. Buy protected ones for extra safety measures.

a brake hone or a wire brush you can chuck in a drill would be my way.
best flashlight forum is blf
a maglight is a super mod host.
i have 2 i built that give over 4000 lumens.
can start fires with it.
stock they are underwhelming though.
but they can serve the average user very well.
a modern led mag gives around 200 lumens and can run a very long time on a set of d cells you can get anywhere.
thats priceless in an emergency.
the club capability can be handy too.

I have a Streamlite, too, and they're fantastic, but they aren't great at protecting oneself, either. A little flashlight is great on one's belt and is unobtrusive and easy to wear all day without noticing it. A Maglite is meant to be carried. wink
