Yes, I agree it is different. I'd not heard of a film on the electrode before.

Sorry Gail, I'm not a very literal person. I surmised that you lived in the city
from what you've said before. That was my idea of a joke, sorry.

Shame! They are so far away but then the upside is that they don't block your
view and you have something to look at.

Ouch! But at least your room must be airy.

I was using the term 'film' because I lacked a better term at the
moment. It's a buildup of 'something'
I got curious and looked up a few sources
I'm not crazy - I actually found something.
apparently it is called a 'passivation layer'
http://www.spectrumbatteries.com/id6.html
http://www.electrochemsolutions.com/pdf/Passivation.pdf
http://www.bealecorner.com/trv900/battery/lithium.html
I believe it has to do with low current draw.
Low current does not burn off the passivation layer that forms, yet you
do not see much affect because the current draw is low and the internal
resistance drops little voltage.
But as soon as you need a higher current from a battery with a big
passivation layer, the voltage drops due to the internal resistance.
Most electronics sense the low voltage and indicate low battery and shut
off.
If they would stay on for a couple of minutes the passivation layer
would be burned off and the voltage would return to normal.
I don't know what 'chemistries' of Li-ion batteries have this problem -
apparently someone thought the SONY Infolithium batters did.

I just found a TV that also contains 6 famous paintings which you can
watch instead of watching TV... WTF?

That was very interesting now I'm worried about the heat transfer from my CPU
core to the battery. :)

No big deal I suppose if you include a start up timer

Now *that* is a good idea. You hang up a huge TV on a flat wall, and when
you're not watching TV, it looks like a painting instead of a big flat chunk
of pointless glass.
Slow glass would be even better, but they haven't invented that yet.

The NFL should go international. I'd pay to
see the Detroit Lions vs the Roman Catholics.

And that was a very tongue-in-cheek reply...

You do know your 1960's SF :)
Have a brownie point.
