I recently purchased a replacement battery from an eBay seller. I was looking for a NFC battery, and that was the item pictured, so I ordered one.

When the item arrived, I realized that it was NOT an NFC-equipped battery. I notified the seller and his response was t#Fair enough. I did a little research and found that a lot of fake batteries are sold as OEM (Original Equipment Manufacturer, in this case Samsung).

Why do they do this? Mainly because an OEM battery is worth $10+ (in the stores, such a battery is about $30), while an aftermarket one is worth less than $5. So there is money to be made in faking it. I also discovered several tests that would allow me to tell if a Samsung battery was genuine.

Test#1: The Back of the Label

In this video, the author claims that the back of the label of an authentic OEM battery is a pewter color – the same color as the front of the label – while the back of label of a counterfeit battery is a silvery color.

label color

Verdict; FAIL

Also note that the label of the original battery opens from the left, while the eBay one opens from the right. While not conclusive, this is certainly cause for concern.

Seller’s response: “We get these direct from our actual Samsung distributor which is our Samsung supplier and they jut informed me that the batteries come from different manufacturers and not all them will have the same information on them…” Oooo-kay…

Test #2: Serial number printed on the battery

According to Samsung, all batteries have a serial number printed on the battery under the label. You can see this in the battery on the left. There was no such serial number on the battery on the right.


Verdict: FAIL

Test #3: QR-Code

Samsung batteries have a QR Code printed on them. Both batteries had a QR-Code, but only the code on the the original battery that came with my phone was readable. The code on the eBay battery could bot be read no matter how hard I tried. Verdict: FAIL

Test #4: Model and Serial numbers printed on the label.

I contacted Samsung and asked them to help me with the model and serial numbers. According to them, the model number printed on the eBay battery was a proper Samsung Part number, but the part in question was an NFC-equipped battery – which this battery was not. Samsung’s response was to “contact the suppler”, which is a polite and legally-safe way of saying that they did not believe that it was genuine.┬áVerdict: FAIL

The seller offered me a full refund.

    Additional: A few weeks ago, the battery started to fail spontaneously. At first I assumed that it was a glitch in the phone, but the problem got progressively worse. A few minutes ago, I finally gave up and threw it away.

    The three-year-old original battery is still going fine.
