Acer Extensa 4010 Battery
Your Acer Extensa 4010 battery allows you to move freely about so that you can use it where you want. More amps in a battery basically means the longer it will last on a single charge. Because no battery is the same, make sure and double-check the part number of the new battery and compare it to the old one. Getting a battery with a higher amp rating is OK, it simply means it is a stronger battery. What is important is the connection type and physical size of the battery.
Major signs the primary battery is failing
- The Acer laptop refuses to turn on when it is unplugged
- The battery has its case swollen and looking like it is going to burst
- The laptop lasts way less than it used to while using the battery only
