Hi, There is no offline market for samsung batteries. You should replace your battery with the Samsung care service center. if you don't trust your local service center, no fraud practice will be allowed. They will give you an original Bill.visit your next nearest center. There is no other way. Use only genuine parts. Cheers.
For online you can see amazon (but won't rec if you don't know what to see & there's a chance of it being **bleep**)..or use official service center they'll not give you **bleep** as it's offcial also check the price in website before going (the shown price won't be final it'll be that price +gst & service charge) and if you have maintenance mode turn that on before giving the phone
As per your query, we want to inform you that we does not recommend to customers to purchase parts for product from online sites, however, we would suggest you to kindly visit near by Samsung authorized service center, they can provide you original parts for your product invoice with proper service.
