Sony VPCEF44FX Battery
Your Sony VPCEF44FX battery allows you to move freely about which gives you the opportunity to use it anywhere you please. The more power the battery has, the longer it will last when fully charged. It is OK to buy a battery with more milliamps, as it signifies that the battery can last for a longer period of time on one charge. What is truly important is the actual size of the battery and the connection it has. Because no battery is the same, make sure and double-check the size and model number in order to make sure it is similar to the one you are going to replace.
Main clues the li-ion battery will need to be replaced
- The laptop battery gets puffy and looking like it is going to burst
- The Sony laptop will not boot up while unplugged
- The laptop lasts under 20 minutes before it shuts itself down
