Apple recalls selected 15” Powerbook batteries

If you bought a 15" G4 Powerbook or a replacement battery for your Powerbook between January and August of 2004, caveat user! Your battery could potentially overheat, causing a fire hazard, according to an important safety recall from Apple.

No injuries have been reported, but Apple urges you to remove your battery after receiving four reports of overheating. A new replacement battery will be sent, free of charge. You can
begin the exchange process on Apple's web site.

Be sure to first check the model and serial number of your battery before panicking: only a subset of the lithium ion rechargeables are affected. Your battery must have Model Number: A1045 and a serial number that begins with: HQ404,
HQ405, HQ406, HQ407, or HQ408.  If your battery has a different model or serial number, commence the dance of joy and compute to your heart's content!
