...Did you get them from eBay? They could be fakes, there was a user having this exact problem a few days ago and the batteries ended up being forgeries. Post some pictures of your batteries, specifically the top(positive pole) as it should have only three connection tabs if it is an authentic 25R.

Yep, looks exactly like that. Only mine still has the plastic wrap on the outside.
Mooch may have something else to say, but in that case it's probably real.
Sounds like it may be genuine. Maybe they could have sold you a used battery that has lost capacity so no longer performs to its original specs.
The INR cells are "lithium-nickel-round" which is another way of saying it's a lithium-nickel-manganese-cobalt (NMC) hybrid cell. Not quite as safe as a true IMR, lithium-manganese, cell but still a lot safer than the ICR, lithium-cobalt cells. The addition of cobalt and nickel allows for easier tweaking of the chemistry for things like high CDR.
I believe the VTC5 and VTC4 are INR cells too.
[edit] But I have seen a Samsung document that describes the chemistry as NCA, nickel-cobalt-aluminum. Another hybrid chemistry that typically doesn't allow for higher CDR's. But since the model number of the 25R includes the term INR I am inclined to think that the documentation I saw had a typo.
Ok, thanks. I thought it had to be something like that. I knew the Old Skool ICRs were to be shied away from in the absence of protection, but INR didn't mean anything to me.
There is a truly ridiculously complicated array of cell chemistry acronyms, a crazy mix of corporate designations and actual abbreviations for some of chemistry's components.
Impossible they were sold by Samsung. They dont sell those directly to the public.
Would you trust them is it read - Failed?
Why would the Box be marked with anything unless they were Used, Tested Cells. You unfortunately purchased from a Vendor dealing through Amazon that probably recycles. You should contact Amazon about a faulty Purchase and see if they will exchange.
Likely only one cell is weak, but used in a set it will ruin the second cell sooner.
I have the same batteries and mod. Mine have no limit when they have enough charge. The mod reads voltage under load and will shut you down if that goes too low. If your batts were fully charged and you got that message IMO the batteries are counterfeit.
Only buy batteries from trusted sources like Authentic AW Batteries - RTD Vapor
Amazon and Ebay are not trusted sellers for batteries. I could go on to one of those sites and create a username like 'Sony,' wrap AA's in a green wrapper and sell them as VTC4's just using a stock photo. There have been 3 threads on counterfeit/fake 25R's in the past week, all resultant from buying on Ebay or Amazon.
Sorry this happened, but I hope you won't buy from there again.
ETA: Please, go to that seller and leave some negative feedback so we can reduce the number of people getting duped.
