[Yaesu] HAZARD-Charging a new battery for VX5R

[kc3vo at aol.com]

It is true for perfectly GOOD Lithium ION/Polymer batteries! At or 
below 32 degrees F, charging will cause pure lithium to plate out of 
solution, rendering the battery hazardous, and damaging it. Good 
chargers will not charge in a cold environment because of this! (If all 
else fails, read the manual) High temperature charging varies according 
to exact battery chemistry and charger type, but most are not advised 
to be charged above 110 degrees F, many have even lower limits. KC3VO, 
Bob Curry

AFAIK this is only true for defective batteries.

Do not charge LITHIUM batteries in the COLD!  Attempting to do so, you  
will
separate out the LITHIUM metal, as a pure electroplate, and damage the
battery/create a firebomb, if the charger does not stop you! These, and 
most
other batteries should be charged at normal room temperature, near 75
degrees F.
Other batteries may charge poorly, but it can be DANGEROUS to charge a
litium battery that is too cold or hot!
                                                   Please be 
careful!--73,
