Sony VGN-Z540N Battery
Your Sony VGN-Z540N battery allows you to move freely about which gives you the opportunity to use it anywhere you please. It is OK to buy a battery with more milliamps, because it simply implies that the battery will last longer. What is important is the actual size of the battery and the connection it has. Not all batteries are the same, make sure and double-check the size and model number in order to make sure it is similar to the old one. More amps in a battery basically means the longer you will be able to use the laptop on one charge.
Some clues your battery should be replaced
- The laptop battery is puffed up and looking like it is going to burst
- The Sony laptop refuses to turn on while unplugged
- The laptop does not last longer than 45 minutes while using the battery only
