Hi @narutofan1987
Here's the http://h10032.www1.hp.com/ctg/Manual/c01037995.pdf|maintenance and service guide] for the laptop.
Go to p.40 to find the HP spare part numbers for the batteries that can be used in the laptop.
The battery model number should also be printed on your battery as well if you want to verify which one you have now.
Search for the ''battery model number'', to find suppliers that suit you best.
