Defect battery. (Not Cmos)

Hey Community, 

I got This Beautifull Laptop. I bought Him 5 years ago, because his fancy rainbow keyboard.

He is still working perfectly. Only the Batterie is weak. I wanted to buy a new one original HP, but they tell me they don't have it anymore. Is this possible? Can you give me an example for a good noname Batterie which is safe and don't have security issues. Or do you know websites were I can sell it for a good money, to buy me a new one?

Sorry, for my bad English and thanks for everything answer.

Normally HP does not stock spare parts such as batteries, we have to buy elsewhere using part # . For a 5 years old machine now, my suggestion is to keep it as a second machine or give it to charity, no one would pay more than US$200 for it.

Regards.
