Acer Aspire 7740G Battery
Your Acer Aspire 7740G battery makes your laptop portable so as to work or play anywhere you please. The more power the battery has, the longer it will last on one charge. Buying a battery with a higher milliamp rating is fine, because it simply implies that the battery will last longer. What is truly important is the actual size of the battery and the connection it has. Not all batteries are the same, make sure and double-check the size and model number in order to make sure it is similar to the one you are going to replace.
Symptoms your battery has little time left
- The Acer laptop is unable to boot up while not connected to the AC adapter
- The laptop does not last longer than 45 minutes before it dies
- The battery has its case swollen and looking like it is going to burst
