Acer Aspire 3640 Battery
Your Acer Aspire 3640 battery allows you to move freely about so that you can use it anywhere in the house or even outdoors! 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 important is the actual size of the battery and the connection it has. The larger the battery, the longer you will be able to use the laptop on one charge. Because no battery is the same, make sure and double-check the physical connection and size and compare it to the old battery.
Signs your battery is dying
- The Acer laptop will not boot up when not connected to the charger
- The laptop lasts less than an hour before it shuts itself down
- The battery gets puffy like its about to burst
