6If you are inserting another battery, remove the battery cap from the new battery to expose the contacts, then slide it into the battery compartment.
You cannot insert a battery if the battery cap is still on the battery. You can replace the battery with another LiIon battery or a nickel-metal-hydride (NiMH) battery. Make sure you only use a battery that is designed for your Macintosh PowerBook. You should store the battery cap in case you want to remove and transport the battery later.
7If 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. You can look at the indicator lights on the battery to see the level of charge.
IMPORTANT Lithium ion (LiIon) and nickel-metal-hydride (NiMH) batteries contain metals which 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.
mIn 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.
mElsewhere Many locations have government or Apple-sponsored collection and/or recycling programs for spent batteries. Dispose of spent batteries in accordance with the mandatory or voluntary battery collection programs in your location. Contact your Apple-authorized service provider for information about the recommended disposal procedures in your area.
Maximizing work time
Your Macintosh PowerBook’s battery can provide 3–5 hours of work time before you need to recharge. The actual work time available depends on which model of Macintosh PowerBook you have, what equipment you’re using with your computer, and what steps you take to conserve power while you work.
For battery conservation tips, see the “Batteries & Power” topic of Macintosh Guide, available in the Guide (h) menu.
