Can I use heat to loosen a Mag Lite battery cap?

[mrbreezeet1]

Soak it in a weak acid solution and it will dissolve the corrosion (or dip it in a strong solution more briefly). Unless it has eaten away parts, it will work again. Flashlights are incredibly simple.

Yeah, maybe white vinegar?

What did MagLite advise when you sent them a message inquiring? I've always found their CS to be excellent.

How did you know I contacted them?

I'm going to soak it in white vinegar today!

Personally, I would not be afraid to heat it with a propane torch.

My buddy said NO! It's dangerous! Because there are batteries inside.

Well, I figured anyone intelligent would have and saw no signs, yet anyway, you aren't so I presumed.

The heat won’t affect the corrosion. The acid will, because the battery corrosion is basic (alkaline battery - potassium hydroxide).

For a car battery (sulphuric acid), you should clean it up with a base.

It's been soaking Overnight! Going to try to open it in a bit here!

The white vinegar did it! Soaked it overnight and hit it with a small hammer about 100 times and got it loose with two Cobra water pump pliers.

Chuck it in the trash can. Never had a reliable mag light. Finally stopped buying them.

I know it was suggested to just toss it if it was the old one, but it would still be a good little flashlight to have at my desk, for the price of 2 AA batteries and maybe a new bulb.

It's something for me to putz around with in the winter, upstairs at my desk. It's too cold in the garage right now.

I had a 2-D Maglite that I had to pull the switch out the top in an attempt to get the corroded Duracels out. Those batteries were welded solid in the tube, couldn't hammer them out so the entire thing was tossed.

I had retro fitted the krypton bulbs with Mag's LED bulbs in the two, 2-D cell lights I have. I dropped one and have since gone back to incandescents.

What if they would have told Thomas Edison to just "toss that light bulb contraption" you've been fooling with?
What if they would have told Alxander Grahm Bell to "just toss that stupid phone thing" you've been monkeying with?

The LED's are no good?

I've had Maglite flashlights forever. Dependable and reliable and they work even after being dented from handling accidents. Most importantly, made in USA. Have a 2AA next to my chair and a 3D in my car door pocket. My best half has a 2AA on her dresser. Somewhere my 6D that's 47 years old is lurking. Great lighting tools.

Are you using any of the LED maglights?

 

[mrbreezeet1]

I'll dial it in, in the 4 jaw and bore it out if I have to!!!!!!!!!!!!!!
I am bound and determined to repair this thing!

 

[LDB]

Are you using any of the LED maglights?

Yes, the one by my chair and the one in my car are both LED. The 47 year old 6D is not. I'm honestly not certain about my best half's light.

I would dip the end, just the cap on the end, in boiling water. while keeping the cylindrical body cool as possible.

Boiling water will be 212 degrees. Not excessively hot. You will expand the cap with the heat.
