Acer Aspire A315-21 Battery
Your Acer Aspire A315-21 battery allows you to move freely about so that you can use it anywhere in the house or even outdoors! More amps in a battery basically means the longer you will be able to use the laptop on a single charge. Buying a battery with a higher milliamp rating is fine, it simply means it is a stronger battery. What is important is the physical size of the battery as well as the connection. Not all batteries are the same, be sure to check the physical connection and size and compare it to the old battery.
Subtle cues to watch for in a failing battery
- 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 when it is unplugged
