Removing corroded batteries from a flashlight

If you have a long enough bit, drill into the battery with a bit just smaller than the battery diameter. You may break it free or be left with just a shell and might be able to use a long screwdriver and a pick to pull out the pieces. I did this once. I guess you could drill into the battery and run a screw into it and try and pull it out.
 
Rather than banging on the table, use a rubber mallet. Hold flashlight with open front end down, whack flashlight butt with rubber mallet.

Rubber mallets are really useful. Cheap, too.
A man after my own heart. 1st solution to every problem is wack it with a hammer ;). Not so sure about that rubber stuff though.
 
Perhaps I'll take the hit someday. I currently use between 130 and 260 AA batteries annually, depending. I use Duracell with no issues going on since Oct 2022. these are all outdoors in trail cameras. Currently have 17 active cameras with 2 in reserve.
 
Baking soda is Alkaline so putting it in a corroded Alkaline battery compartment does nothing. Yes, it works on car battery terminals but those are acidic.

Call Duracell and send a picture they will reimburse you the price of the flashlight
 
Had a similar thing happen to me. Managed to get the stuck item out, but don't recall how. I was able to get both head and tail cap off. Removal may have involved a steel bar, hammer and hardwood block.
 
I get most my batteries off eBay or at Dollar Tree, usually off brands. Don’t remember having any corrosion problems. Not long ago, I bought a 24-pack box of generic AAA alkaline batteries from eBay. They sent me two boxes. Should last me for a long time. I figure that all batteries probably come from the same Chinese factory no matter what brand is stamped on them.

We had a thread here years ago where most posters all chimed in and agreed completely that Duracell is AWFUL. I remember that discussion and nodded my head because I knew every leaking trashed alkaline I’d had was damn Duracell.

took me a while, but I finally convinced my much better half that even free duracells were not a bargain and she has stopped buying them... smae ruined flashlight issue.. and one emergency radio...
Exactly this. Amazon had a whopper of a sale on decent electronic ear pro years back and I ordered a bunch of them and each set came with a shrink wrapped pair of Duracell and each *free* Duracell got tossed.

They’re worse than junk. If something is junk, it usually doesn’t perform well. But Duracell wrecks the device you use them in.

Worse than junk.
