Apple PowerBook 540 Battery
Your Apple PowerBook 540 battery makes your laptop portable which gives you the opportunity to use it where you want. Buying a battery with a higher milliamp rating is fine, as it suggests the battery will last a bit longer on one charge. What is truly important is the physical size of the battery as well as the connection. The larger the battery, the longer it will last on one charge. Not all batteries are the same, be sure to check the size and model number in order to make sure it is similar to the old battery.
What warnings should I watch out for to know if my Apple battery is not working right?
- The laptop is unable to boot up when it is unplugged
- The laptop battery has its case swollen like its about to burst
- The laptop lasts under ten minutes before it shuts itself down
