Laptop Battery -- LG ED500

Hello,

I have a LG ED500 laptop for which i am searching for additional battery. Its a 10.8V 4400 mAh battery which looks like it has been made by MSI because of the design but i am not sure about it. Can somebody help me out as to where i can purchase a additional battery or a universal battery ?. I tried LG service center ( i dont think any such thing exists).

I am interested in knowing how i can improve my battery life. Like is a 9 cell or 12 cell higher end battery which can replace this available ?

What kind of battery can i replace this with. do i need to get a 10.8v battery itself ?

Are there any universal battries available in India except APC ?

Here are some pics of the battery
