Battery Explosion on a G4! Has anyone seen the article?

I went to today and there was posted a warning from Apple on batteries possibly exploding.
I am posting their article for those interested.

This article explains how to replace the internal battery in a Power Mac G4 (Digital Audio/Gigabit Ethernet) computer. You may also view the following procedure in QuickTime at

Be sure to follow the instructions in this sheet carefully. Failure to follow these instructions could result in damage to your equipment and may void your warranty.

Replacing the battery requires five basic steps:

* Turn off the computer.
* Open the computer.
* Remove the installed battery.
* Install the replacement battery.
* Close the computer.

Note: HTML/QuickTime video versions of the instructions are available at

Tools Required

No tools are required for this procedure.

Electrostatic Discharge (ESD)

Static electricity, a normal and natural phenomenon, builds up on your body as you walk around. You experience an electrostatic discharge (ESD) when you touch an object and feel a spark. ESD can cause damage to the internal components of your computer. Avoid walking around while performing this procedure, and follow the instructions carefully when you are asked to discharge static electricity.

Opening the Computer

Warning: Always turn off your computer before opening it to avoid damaging its internal components.

1. Place your computer on a clean, flat surface.

2. If you think your computer is in sleep, press the power button on the front of the computer to wake it.

3. Shut down your computer by opening the Special menu and choosing Shut Down. Then wait five minutes for the computer's internal components to cool down.

4. If you attached a security cable through the computer's lockable cover latch, remove the cable.

5. Unplug all other cables from the computer except the power cord.

6. Touch the metal PCI access covers on the back of the computer. Important: To avoid electrostatic discharge, always ground yourself by touching the port access covers before you touch any parts or install any components inside the computer. To avoid static electricity building back up in your body, do not walk around the room until you have completed your installation and closed the computer.

7. Unplug the power cord.

8. Lift the latch on the right side access panel

9. Gently lower the access panel until it lies flat. To avoid scratching the case, lower the panel onto a soft, clean cloth.

Warning: If you see any lights glowing on the main logic board, the computer has not been shut down. Close the side access panel and shut down the computer before proceeding.

Replacing the Battery

1. Note the orientation of the installed battery's positive (+) end. (Positive and negative signs are also marked on the battery holder.)

2. Carefully pull the battery up and out of the holder. You may use a flat-blade screwdriver to help pry the battery gently from the holder.

Warning: Batteries contain chemicals, some of which may be harmful to the environment. Please dispose of used batteries according to your local environmental laws and guidelines. Do not return used batteries to Apple.

3. Insert the new battery into the holder, making sure the battery's positive and negative signs align with those on the holder.

Warning: Installing the battery incorrectly may cause an explosion. Be sure the battery's positive and negative poles are correctly oriented in the holder. Use only the battery supplied with this kit.

Closing the Computer

1. Raise the side access panel, lift the latch, and press the panel against the case until it snaps securely into place.

2. Reconnect all cables and restart your computer.

Warning: Never turn on your computer unless all of its internal and external parts are in place and it is closed. Operating the computer when it is open or missing parts can damage your computer or cause injury.

Resetting Date and Time

Replacing the battery changes the date and time settings on your computer. Use the Date & Time control panel to correct the date and time.

G4 Battery Problem

No, I did not see the article. What is the link. If the article was specifically for the G4, it must be something other than the battery. ALL currently shipping Macs (Desktop) and those models from way back, pre-pre G3 Beige, use the same internal battery. So if there is a problem with one, there must be a problem with all of them. 3.6v lithium is the standard battery installed.
Please supply the link for this article.

P. The link I am not sure of, yet it was on main page two days ago. Should be there still now. That is where I copied the article from. Yes, It does sound like a potential problem with all batteries for the G4. Maybe just a warning on not to be blinded by a battery and also a warning so that Apple does not have a potential law suit. Maybe someone was blinded or had something happen that prompted this alert on their main page.
Any other problems with lithium batteries or warnings that you know of other than installing them backward and powering up the G4 with the side door open?
I remember a warning on all batteries years ago that said never put a battery into a fire or to open up!
Most of the goo inside a battery is acid.
Thanks for your intest in this warning.
Back to basics 101? Maybe, and safety!

The article you are referring to was in reference to the 15" POWERBOOK G4 Battery which is a Lithium-Ion battery. They are being recalled and replaced because they pose a fire hazard.
Your rather lengthy article on replacing the 3.6 Volt Lithium battery in a G4 Tower was factually correct but not relevant.
So, not need to worry. All is well with the world and the stock of 3.6V DESKTOP batteries.

Almost True

P. Went to Apple about 4 minutes ago and noticed the battery recall is for the Powerbook. Not the tower. The Warning notice is on the Apple main page with a link to the article.
