I am trying to get the two AA batteries out of a "Mini Mag type"
flashlight. The batteries are dead and swollen up. They are tightly
stuck in the flashlight body. Any hints about how to get them out would
The way this light is built I can only get at the base end of the
batteries. The light was made by Brinkmann.

If the batteries have swollen that much they are probably leaking. This will
raise havoc with contacts, swiches etc.
Time for a new flashlight. Get one of the LED ones. A little more money, a
lot more light and battery life.
Very carefully drill into the base of the cells. You may then be able
to use a screw or screwdriver to pull out the remains of the cell/s.
If not drilling several holes will destroy the cells and they can then
probably be chipped and levered out piece by piece with an old
screwdriver. Use plain water to wash out the flashlight case and
screwdrivers etc. to get rid of any of the corrosive alkali that has
probably seeped out of the swollen cells.
I do seem to recall doing this once many years ago. Older style
batteries were often, then, cardboard encased, unlike present day
BTW can you get at the 'other end' of the flashlight body to help
drive out through, bits of the swollen cells, using. say, a piece of
wood dowel etc.?
BTDT, not worth the effort unless its just curiosity. My suggestion
is, invoke the battery warranty....they usually send a check (or
coupon) for the flashlight & a coupon for the batteries.
I've done this with DuraCells several times since in my experience
DuraCells & Maglights don't mix well. One reason why I switched away
If you really want to get the batteries out, you can drill them out.
Be careful, getting hurt isn't worth the price of a mini-maglight.
A brinkmann isn't worth loosing any skin over. Dunk it in hot water,
and if that doesn't do it, bin it.
If you REALLY love the flashlight, drill a small hole in the end of
the battery and screw in a honking bug screw-eye to pull on.
Pick a battery company - ANY battery company - and send the flashlight.
Either they will send back a new flashlight without bothering to remove the
batteries or they will remove the batteries. If they remove the batteries
and they are their brand, they will send back a new flashlight; if the
batteries are not theirs, they will send back the old flashlight (possibly
with a shipping charge) but the batteries will be gone.
Now would be a good time to plug:
best flashlight bang for the buck and you don't even have to mail order
it. (I have two. They kick my old 3D LED Mag-Lite's arse.) Only
downside it it may not be waterproof, but the only weak spot seems to be
the switch. If you get a silicone seal for that and then put some
silicone on all the threads/O-rings it probably would be.
replace "roosters" with "cox" to reply.
I gave up after about one hour of trying to remove the batteries by
drilling them out. They are still stuck tightly.
Thanks to everyone for the comments.

It's a pain, but to remove the DuraCell junk from my MagLight I took a
slide hammer which has a small chuck or collet at one end. I inserted a
dry wall screw, drilled a small hole in the bottom of the battery,
threaded the screw in and hammered out the battery.
Clean up with water and baking soda or soap, etc., rinse well with clear
water, and dry. If you have a vacuum chamber use it to dry the
flashlight, otherwise let it air dry for a couple of days before closing
the flashlight up.
