Apple PowerBook 540C Battery
Your Apple PowerBook 540C battery allows you to move freely about so that you can use it inside, outside or anywhere your heart desires. Not all batteries are the same, be sure to check the part number of the new battery and compare it to the old one. Getting a battery with a higher amp rating is OK, as it suggests the battery will last a bit longer on one charge. What is important is the connection type and physical size of the battery. The more power the battery has, the longer you will be able to use the laptop when fully charged.
