As far as lithium battery disposal is concerned, for some of our
products, we have had to include the required warning from UL1950,
1.7.17, in our manuals, namely "CAUTION, Danger of explosion
if battery is incorrectly replaced. Replace only with the same or
equivalent type recommended by the manufacturer. Dispose of
used batteries according to the manufacturer's instructions."
It certainly seems to be a complete waste of time including this,
as it is open to question whether there really is a "danger of
explosion", and also since we don't provide the manufacturer's
disposal instructions (which for one manufacturer was
"dispose of according to local regulations"), there is no guidance
for disposal.
Looking at a UL report from a well known manufacturer of lithium
batteries, they seem pretty robust. The test record shows:
temperature cycling at -54 and +71 degrees C, short circuit
tests, heating in a sand bath at 180 degrees C, being crushed,
vibration,forced discharge and charge, drop tests, etc. At no
time was there any any evidence of any "danger of explosion",
so maybe we should argue that there is no need for the above
statement - but it's sometimes easier not argueing with UL !!
