There have been some very good fake 25R’s popping up lately. Thanks to some fantastic members of this community who sent their fakes to me for testing I have some idea of what’s going on.<\/p>\n
Most of the fakes are identical in appearance and performance to the 10A 2050mAh Samsung 22P battery. This battery is a terrible performer compared to the 25R. One fake was much worse than all the others. It might have been a lower grade 22P or damaged during use before I received it.<\/p>\n
But I have one fake that is different from the others. It has the metal can code for, I believe, a Samsung 29E. But the top contact structure seems wrong for the 29E. I don’t know for sure what this fake actually is. It’s performance is lousy compared to the 25R though.<\/p>\n
One HUGE problem with these fake 25R’s is that the top insulating rings are free-floating and not self-adhesive and glued down to the battery! This is the first time I have ever seen this. We can no longer say that a battery with a free-floating ring is genuine.<\/p>\n
But here’s how to spot these fake 25R’s:
\n– If there are any lines radiating out from the center of the venting disk under the top contact then the battery cannot be a 25R. There are four of these lines in the fakes, spaced at 90\u00b0 intervals. If you see even one though, as they are hard to spot, the battery cannot be a 25R.<\/p>\n
– You can see the venting disk without unwrapping the battery but you’ll need a bright light source and a magnifier is very helpful.<\/p>\n
– If you do not see any of these radial lines in the venting disk that does NOT mean that the battery is a genuine 25R. Other fakes might not have the lines.<\/p>\n
– If there is anything other than a “5” as the second character in the uppermost four character code on the metal can, near the top, then the battery CANNOT be a genuine 25R. If it is a “2” then it’s most likely a rewrapped Samsung 22P. You can see this code through the wrap.<\/p>\n
– If there are no codes on the metal can then it’s a fake 25R. It might still be a Samsung but someone has washed off the codes.<\/p>\n
– The batch codes on the wrap CANNOT be used alone to detect these fakes as they might be genuine batch codes. The codes for the fakes I have are 2G22 and 2F34, located at the end of the second line of printing on the wrap.<\/p>\n
– I want to say this again…these batch codes might be genuine and cannot be used as the only method to check for authenticity.<\/p>\n
– There might be other batch codes being used for these fakes. Do not assume that having a batch code other than 2G22 and 2F34 means you have a genuine 25R. Check the venting disk for radial lines.<\/p>\n
That’s all I have for now.<\/p>\n
If you do have any fakes I recommend not using them at all. Contact the vendor you purchased them from to see what can be done.<\/p>\n
Please do not send me pictures of your 25R’s to authenticate them. I am unable to do so via photographs.<\/p>\n
Hoping your 25R’s are genuine!<\/p>\n
