Acer Extensa 4620 Battery
Your Acer Extensa 4620 battery allows you to move freely about so as to work or play wherever you fancy. Because no battery is the same, be sure to check the physical connection and size and compare it to the one you are going to replace. The more power the battery has, the longer it will last on a single charge. Getting a battery with a higher amp rating is OK, because it simply implies that the battery will last longer. What is important is the connection type and physical size of the battery.
Easy warnings to watch for in a failing battery
- The unit will not turn on when not connected to the charger
- The battery gets puffy and looks like it will explode
- The laptop lasts way less than it used to while using the battery only
