Apple Macintosh PowerBook 1400 - Manual (Page 82)

5 Put the battery cap on the battery to protect the battery contacts.
6 If you are inserting another battery, remove the battery cap from the new battery to
expose the contacts. Then slide the battery into the battery compartment.
You can replace the battery with another NiMH battery. Make sure you only
use a battery that is designed for your Macintosh PowerBook. Store the
battery cap in case you want to remove and transport the battery later.
You can store an extra battery in the expansion bay if no module is installed
there.
7 If you just inserted a new battery, it’s a good idea to plug in the power adapter in case
the battery is not fully charged.
IMPORTANT Nickel-metal-hydride batteries contain metals that are hazardous
when released in the environment. It is inappropriate, and in some cases
unlawful, to throw batteries away with your household or business trash.
Instead of throwing away your spent batteries, dispose of them as described
here.
m
In the United States Return spent batteries to your Apple-authorized service
provider, who will make sure they are included in Apple’s battery recycling
program.
WARNING Always put the battery cap over the metal contacts when the
battery is not in the computer. If the battery’s metal contacts are not
covered, a short circuit could occur, creating a safety hazard.
Always snap the battery
cap on the battery when the
battery is out of the computer.
