Battery Information
Warning:
(LiIon)battery supplied with the PowerBook 3400, or an
identical model. Batteries designed for other portable
computers may look similar, but they may not work with
your computer and may damage it.
The LiIon and nickel-metal-hydride (NiMH) batteries look
similar. To distinguish them,
For the main battery, use only the lithium-ion
• Read the label on the battery, which will identify the
battery as either “LiIon” or “NiMH.”
• Look for battery indicator lights; if the battery has
them, it’s a LiIon battery.
Basics Battery Information - 10
Main Battery
For its main battery the
PowerBook 3400 computers
use a lithium ion (LiIon)
battery. Each battery
provides power for up to
four hours of work time,
depending on the system
configuration and battery
conservation features
employed.
Note
: Although this battery
fits into a PowerBook 190/
5300, the PowerBook 190/
5300 will not recognize or
charge it.
Basics Battery Information - 11
Optional Battery
The PowerBook 3400 can also use a nickel-metal-hydride
(NiMH) battery. This battery provides somewhat less work
time; the precise amount of work time depends on the model
you have and the battery conservation features you use.
Battery Handling Guidelines
The following are guidelines for properly handling the
PowerBook 3400 batteries:
Warning:
should not be thrown out with household or office trash. Take
dead batteries to an Apple authorized service provider for
recycling or proper disposal. Review battery handling and
disposal instructions in Safety Information in Bulletins/
Safety.
LiIon batteries contain hazardous chemicals and
Basics Battery Information - 12
• Handle the battery carefully. Do not drop, puncture,
disassemble, mutilate, or incinerate it.
• Do not leave a battery in the computer for longer than a
week without plugging in the power adapter.
• Always put the battery cap on the battery when the
battery is out of the PowerBook. The battery contacts
should not be exposed when the battery is out of the
computer.
• Do not leave the battery in hot locations (such as the
trunk of a car).
• Do not leave a battery in storage for longer than six
months without recharging it.
• Never get batteries wet.
• Do not short-circuit the battery terminals. Doing so may
cause an explosion or a fire.
• Recharge batteries only as described in the user’s
manual and only in ventilated areas.

Battery Matrix
For a matrix of batteries that work with specific models of
the PowerBook family of computers, select the PowerBook
Battery Matrix located in Hardware/Compatibility Charts.
Basics PC Card Handling - 14
PC Card Handling
Two PC Card slots (also
known as PCMCIA slots) are
featured in the PowerBook
3400. The two slots accept a
variety of third-party PC
Cards with 68-pin
connectors.
There are three types of PC
Cards: Type I (3.3 mm),
Type II (5 mm), and Type III
(10.5 mm). Type I and Type
II cards fit in either the
upper or lower slot of the PC
Card unit. Type III cards can
only be placed in the lower
Basics PC Card Handling - 15
slot. When a Type III card is in the lower slot, the upper slot
cannot be used.
The following are guidelines for properly handling PC Cards:
• Use only cards that are compatible with the PC Card unit.
Refer to the compatibility information that came with the
card. If you cannot find the compatibility information,
call the card vendor.
• Do not insert anything other than a PC Card into the card
slots.
• The computer must be on or off in order to eject a PC
Card. When the computer is in sleep mode, a PC Card
cannot be ejected.
• Before you eject a card, make sure nothing is blocking
the card’s slot.
• If you want to use the card again immediately, pull it out
about an inch more and then push it back in. If you don’t
Basics PC Card Handling - 16
follow this procedure and try to push the card back in to
use it again, the card will not engage properly.
• Do not pull on a PC Card before it has been ejected out of
the slot. Forcing a PC Card out of the slot may damage the
computer or the card.
