This is neither a forum nor google groups.
This is Usenet news.
Google groups is jut a web based method of reading it.

If you want to post pictures, get a DropBox account, upload them
and post the link here.




Someone could start an alt.bin.sci.electronics.repair Usenet group for
photos...however I don't think binaries are supported much any more.

That package looks like it may have been frozen.


Nope. The white stuff is KOH (potassium hydroxide) which kinda looks
like frost. What's interesting is that the leaky cells in the photo
that I tested showed good on a voltmeter. I've also opened the
battery compartment on a working device, that showed a good battery on
its LCD display, but which contained cells that were leaking all over
the battery compartment.

I beg to differ. I have had NiCd and NiMH cells leak. The difference
is that unlike alkaline, they don't leak in the package:

I've found from dealing with commercial walkie-talkie batteries, that
if I leave the packs totally discharged for more than a few weeks, the
batteries will leak. The good news is that this rarely happens.
