Sony VPCCW290X Battery
Your Sony VPCCW290X battery makes your laptop portable so that you can use it where you want. The more power the battery has, the longer you will be able to use the laptop on one charge. 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, be sure to check the model number and compare it to the old one.
Red flags to watch for in a bad battery
- The battery gets puffy like its about to burst
- The laptop lasts less than an hour before it dies
- The unit will not boot up when it is unplugged
