The remaining unsolved battery problem

 Leakage problem that is - I have this coffee mug full of pens, I started going through them to see if they still write.  Then I tried turning on an LED light pen, seemed fine.  But a second light pen beam was weak.  Uh-oh !

I opened the second pen up and found this:

the dreaded alkaline whiteness !

So I pried out the cells to see how badly the contact is corroded.  It's not too bad but it'll go in the corroded item box to be cleaned and re-used "one of these days".

It wasn't that handy a pen anyway, for one thing, the light shines the opposite way from the pen tip, so not much good for writing in the dark.

Will anyone ever solve the battery leakage problem for button cells the way the Energizer Ultimate Lithium AA, AAA and 9V batteries did ?

I can only hope.
