ASUS X53SR getting replacement battery

Hi i purchased a ASUS X53SR from pc world other day it was a x display and when there went to get box and stuff it was`nt there it was the last one in the store so decided to still get even though there was`nt a battery with it either, anyway got a discount with the intension of buying battery myself of the net, well i can`t seem to find anywhere that sells them,so if anyone can help me out here and send me link to buy a battery or is the a battery that is compatible with my x53sr that works? thanks

 

Reading some of the post on this site people are stating laptop ASUS X53sr/F3sr i can find batterys for the F3 so will battery work in my X53SR?

 

Trouble is that Asus uses the same chassis and then names them differently depending on where in the world it's sold sometimes. Look at the serial number tag on the bottom of the notebook. It would probably say something like F3xxxx. If that's the case, then any F3 battery will work.

 

Thanks you
