True for the defective Sony laptop batteries. Probably not true for
cheap replacement cell phone batteries. It won't take much for you
find numerous exploding cell phone horror stories with Google.
Although some of the early exploding batteries were OEM batteries, the
greatest majority were apparently cheap aftermarket replacements.

There's a big difference between your anti-competative chips in ink
jet cartridges, which have no safety issues, and a similar chip in a
potentially exploding cell phone or laptop battery, where safety and
liability are currently a serious and real concern.


So all those flaming Dell computers with legit batteries have protected who from whom? Maybe the after market ones would have been safer!
Its all about Money, not safety.


I believe it was lexmark that got sued and lost for the printer fiasco.
