The manufacturer's original batteries, and as the case for the Samsung model that is the subject of this opinion. This is the same battery pack that came with the new phone, so no problem.
Either generic batteries that are rated slightly higher. In this case, they are 1,700 Mha Mha for 1500 against Samsung. They usually cost less and, in my experience, have a service life equivalent to the original.
But who wants to have absolutely no problem (personally I have never had, regardless of the battery type) you can buy this Samsung sold at a very competitive price.
Those sold on Amazon seem to be made in China, while that comes with the phone is marked made in Korea and assembled in Vietnam, like all new appliances in the Samsung Galaxy range.
You can buy without any hesitation.
