Sony VGN-SZ140 Battery
Your Sony VGN-SZ140 battery allows you to move freely about which gives you the opportunity to use it anywhere you please. Not all batteries are the same, be sure to check the model number and compare it to the old battery. 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. More amps in a battery basically means the longer it will last on a single charge.
Major indications of an unhealthy battery
- The battery is puffed up like its about to burst
- The Sony laptop refuses to turn on when it is unplugged
- The laptop lasts way less than it used to before it shuts itself down
