Laptop Batteries for Sony VAIO
Several Sony VAIO laptops use similar batteries and so some are compatible across many different models. The most model diverse battery that is available is a 5200 mAh with 6 cells and 11.1V, as this is the type of battery that is used the most across VAIO laptops. As such, replacement batteries are widely available for purchase.
One of the main differentiations between laptop batteries is the number of cells, which can range from 4 to 13. The number of cells determines how long the battery will remain charged for until it needs to be plugged in again. In this sense, the more cells there are the better the battery will be and hence the greater price.
This does not necessarily mean that your laptop will automatically take to any battery that you replace the old one with as the voltage is what determines what your laptop can withstand, so when you're buying a new battery for your Sony VAIO, it is important to ensure that you purchase one that is compatible with the model of your laptop.
Another aspect to consider is the milli Ampere hour (mAh), which establishes what the storage energy capacity of the battery is. The higher the mAh is, the more electrical energy it can store. This is a good way to compare batteries when buying as you are able to see if the one you are looking to purchase is better or worse than your current one.
When replacing your old laptop battery, make sure that the system is switched off and the AC adapter is disconnected. Once you have released the latch and taken the old battery out of its compartment, switch in the new one, plug in the AC adapter and give it a full charge before using your laptop again.
