Sony VPCSB390X Battery
Your Sony VPCSB390X battery makes your laptop portable which gives you the opportunity to use it anywhere in the house or even outdoors! Because no battery is the same, make sure and double-check the model number and compare it to the old one. Getting a battery with a higher amp rating is OK, it just means the battery will go further on a single charge. What really is critical to a battery fitting your laptop is the connection type and physical size of the battery. The larger the battery, the longer you will be able to use the laptop on one charge.
What are the indications that my battery has to be replaced?
- The laptop lasts less than an hour while unplugged
- The laptop will not boot up when not connected to the charger
- The battery gets puffy and looking like it is going to burst
