Sony VPCY21SFX Battery
Your Sony VPCY21SFX battery allows you to move freely about which gives you the opportunity to use it where you want. The more power the battery has, the longer it will last when fully charged. Because no battery is the same, make sure and double-check the part number of the new battery and compare it to the old battery. Getting a battery with a higher amp rating is OK, it just means the battery will go further on a single charge. What is truly important is the actual size of the battery and the connection it has.
What are the clues to watch out for to know my Sony battery has gone bad?
- The battery has its case swollen like its about to burst
- The laptop lasts under 20 minutes while unplugged
- The unit refuses to turn on while not connected to the AC adapter
