SWMBO found a metal torch (like a Maglite) in the house. The bulb lit, but was very dim.
She tried to take the batteries out, but the end cap would not budge.
Enter Migalot! "I'll sort that out".
Using mole grips and a Stillson, I was finally able to get access to the batteries, but they were all covered in that white powder associated with a leakage.
Obviously, despite cleaning as best I could (what "dissolves" that leakage sediment?), the batteries won't budge from the main tube. I thought about putting a screw into the battery base and having a good heave. Now, I know that obviously that shouldn't be attempted on a lithium battery, but is it totally safe on a regular AA battery?
