Just a note.... Review by Rob
Rating
As a heads-up for anyone buying these, they are labelled as 5000mah on the site, but they are actually listed as 4900mah on the official spec sheet for the battery at Samsung. Also, if you look at the specs given on NKON, they label them as having a typical capacity of 4900mah.

I'm not sure why they are listed as 5000, but I just thought I'd note this here for anyone buying. I got an instant "Oh no, I've been delivered the wrong thing." Then, on investigation, I realized it was just a listing error. PS I gave it 5 stars because it wasn't fair of me to mark it down, but this isn't a review on the cells' quality. I haven't tested them yet. (Posted on 09-10-24)
