Last week, B&H emailed customers who’d purchased EN-EL15b batteries from them. They said that some of the batteries were “subpar”. It was suspected that this was a euphemism for fake, and according to a statement released by Nikon to DPReview, the suspicions were correct.
B&H has sent out an email to customers who recently purchased Nikon EN-EL15b batteries. Nikon Rumors posted a screenshot of the email, which states that they received a “subpar” batch of batteries, and as they have no way to know which customers received which batteries, they’re sending out replacements to everybody, and advising that you safely discard the ones you have received.
