Sony VGN-AR840E Battery
Your Sony VGN-AR840E battery allows you to move freely about so that you can use it anywhere in the house or even outdoors! Getting a battery with a higher amp rating is OK, because it simply implies that the battery will last longer. What really is critical to a battery fitting your laptop is the actual size of the battery and the connection it has. The larger the battery, the longer it will last on one charge. Not all batteries are the same, be sure to check the size and model number in order to make sure it is similar to the old battery.
What red flags are there that my battery is about to stop working?
- The battery is puffed up and looks like it will explode
- The laptop lasts less than an hour while unplugged
- The laptop will not turn on while not connected to the AC adapter
