"As a Toshiba Corp. marketing executive said to me, "Toshiba
does not guarantee the system's performance, reliability or safety
as they relate to aftermarket batteries.""
"This is ironic, since notebook makers like Apple, Dell, Sony,
Lenovo, Toshiba and others have an uneven record when it comes to
the batteries they sell themselves. Together, they have recalled
millions of bad batteries over the past few years. Some of the
power packs weren't up to spec, while others were potential fire
hazards. So it seems that no battery, regardless of who makes or
sells it, is immune to problems."
