<DIV><FONT face=Arial size=2> I recently posted a note about killing a cell
in a Li-ion pack when you charge it.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>A couple of data points.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>1. These were packs that were two and three
years old.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>2. I could only get one to fail when the pack
was heated up over 140 F externally. i.e. the sun.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Never had one fail in any other way.</FONT></DIV>
