Taking out old batteries in a Maglite

I took the first battery out by impaling it. But on the second battery my chisel twisted out of it’s handle (grr)

Is there an easier way to get these corroded batteries out

I assume you don’t care about the internals too much? Vinegar sometimes works, the idea behind it is the acid eats away at the basic battery chemicals, removing them, and hopefully giving you enough space to knock them free.. then what I do is put a towel over a hard surface and whack the end of the batter tube squarely on it for a while. It will hopefully pop out. If all else fails you can embed a drill bit into it, and pull it out via the drill bit.

If you can’t blind them with your brilliance, baffle them with your bullcrap.

The real currency in the world is not money, it’s trust.

All I know is when you impale the cell you cause it to expand. If you take the lens and switch out, you could pound a dowel through that is almost as large as the cell. Take the rubber button off the switch and depending on the age of the Maglite you would use either an allen wrench or torx 8 to get the switch out.

Or maybe put WD-40 inside the tube, then tie the tube and head very very tightly with paracord and swing it violently in a secure area and let centrifugal force do the job… let us know how far did the cell go when it breaks free :bigsmile:

Some maglite switch assemblies only come out the tail.

Do you have a drill bit extender?

Mount a cork screw into it.

Oo some good ideas here.. I’ll mess with it tomorrow- I was thinking of drilling it out but I’d have to be careful. The vinegar idea sounds interesting too

These batteries have swelled and practically fused to the sides. I wish I could take out the light, it’d be easy. They have this plastic tower that holds the light and it’s under an aluminum lip.

What if you drill 2 small holes or indents in the aluminum (I think its spring steel) lip and use a snap ring pliers to get it out from the front along with the plastic tower then just hammer the battery out?

I haven't had one this bad... On my incan Mag, I removed the bulb, sprayed the battery tube liberally with WD-40, and let it soak for a while. Then, I "hammered" a cardboard box with it a few times. Came right out.

 

Some vinegar first may help, as it neutralizes the alkaline.

Remove the little grub screw hidden down at the bottom of the hole through the middle of the switch button, then tap the tower/switch assembly down towards the rear of the tube, just enough to uncover the snap ring that prevents the tower assy from going out the front of the light. Pull the tower out the front, then you have a clear shot at the stuck batteries from both ends.
