Sony VPCCB4SFX Battery
Your Sony VPCCB4SFX battery allows you to move freely about so that you can use it wherever you fancy. Not all batteries are the same, be sure to check the model number and compare it to the one you are going to replace. It is OK to buy a battery with more milliamps, 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. The larger the battery, the longer it will last when fully charged.
Cues of a weak battery
- The unit is unable to boot up when not connected to the charger
- The laptop does not run longer than one hour while using the battery only
- The battery is puffed up like its about to burst
