Acer Aspire 9420 Battery
Your Acer Aspire 9420 battery makes your laptop portable which gives you the opportunity to use it anywhere you please. The larger the battery, the longer you will be able to use the laptop on one charge. It is OK to buy a battery with more milliamps, as it suggests the battery will last a bit longer on one charge. What is truly important is the physical size of the battery as well as the connection. Not all batteries are the same, be sure to check the part number of the new battery and compare it to the old one.
What are some indications that my battery is failing?
- The laptop lasts way less than it used to before it dies
- The battery has its case swollen and looking like it is going to burst
- The unit will not turn on when it is not plugged in
