Sony VPCEA37FX Battery
Your Sony VPCEA37FX battery makes your laptop portable so that you can use it where you want. It is OK to buy a battery with more milliamps, it simply means it is a stronger battery. What really is critical to a battery fitting your laptop is the physical size of the battery as well as the connection. The larger the battery, the longer it will last on one charge. Not all batteries are the same, be sure to check the physical connection and size and compare it to the old battery.
