Apple MacBook Pro MD103LL-A Battery
Your Apple MacBook Pro MD103LL-A battery makes your laptop portable which gives you the opportunity to use it anywhere you please. The larger the battery, the longer you will be able to use the laptop on one charge. Because no battery is the same, be sure to check the part number of the new battery and compare it to the one you are going to replace. 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 actual size of the battery and the connection it has.
Red flags the li-ion battery will not last the year
- The laptop battery gets puffy like its about to burst
- The unit refuses to turn on at all when unplugged
- The laptop does not run longer than one hour before it shuts itself down
