These are true Genuine Samsung batteries. I do not and will not ever sell fake batteries. Mainly due to safety reasons. I went the extra mile to assure this, contacting Samsung directly to skype video with factory.

Please read entire description below before purchase. I see some sellers receiving bad feed back because of stickers placed over battery content. These stickers are placed there by ALL distributors and there for a good reason. More about that below.

We all know even the best trees can produce a bad apple. If your battery arrives DOA. Send me a message immediately. You must return to me for full replacement or refund. Simply place back in original package and write "return to sender" Or I will walk you through how to print a return label at no cost to you.
