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.

Incidentally, it may not be just the laptop batteries that are
responsible for starting fires:

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.
