Acer Aspire One 521 Battery
Your Acer Aspire One 521 battery makes your laptop portable so as to work or play anywhere you please. It is OK to buy a battery with more milliamps, because it simply implies that the battery will last longer. What is important is the connection type and physical size of the battery. Because no battery is the same, be sure to check the model number and compare it to the old battery. More amps in a battery basically means the longer you will be able to use the laptop when fully charged.
Clues the li-ion battery is in dire straights
- The battery is puffed up and looking like it is going to burst
- The laptop does not last longer than 45 minutes before it shuts itself down
- The Acer laptop refuses to turn on while not connected to the AC adapter
