Sony VGN-BZ540N Battery
Your Sony VGN-BZ540N battery makes your laptop portable which gives you the opportunity to use it where you want. Not all batteries are the same, make sure and double-check the part number of the new battery and compare it to the old one. 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 physical size of the battery as well as the connection. The larger the battery, the longer it will last when fully charged.
What are the clues to watch out for to know my battery will soon go out?
- The battery is puffed up and looking like it is going to burst
- The unit will not boot up when it is unplugged
- The laptop lasts under ten minutes before it shuts itself down
