Acer Extensa 5420 Battery
Your Acer Extensa 5420 battery allows you to move freely about so that you can use it inside, outside or anywhere your heart desires. Not all batteries are the same, be sure to check the model number and compare it to the old one. The more power the battery has, the longer it will last when fully charged. Getting a battery with a higher amp rating is OK, it just means the battery will go further on a single charge. What is truly important is the actual size of the battery and the connection it has.
Simple warnings that your li-ion battery is almost dead?
- The laptop lasts under 20 minutes before it shuts itself down
- The laptop refuses to turn on while unplugged
- The battery is puffed up and looking like it is going to burst
