- After a recent purchase on eBay that turned out to be counterfeit, I thought I would discuss ways to help identify and avoid counterfeit laptop batteries.

Many thanks for this video. There are a ton of sellers on Ebay obviously selling counterfeit batteries while claiming they are
Genuine OEM Dell batteries. They all have the same obvious flaw. The serial number QR code is missing, and the lettering next to the Dell Logo is Blue on the counterfeit batteries, while it is Grey on the Genuine OEM batteries, just like your video shows.
In fact, the counterfeits all get this detail wrong, so Blue Text next to the Dell logo is literally a giant sign saying I AM FAKE...
these batteries fail cus they don't have cell balancing , it just monitors each series and then cut off when one of them goes 4.2v or 2.7v , the cells in them are typically good enough for an old laptop , most of them do perform to their rated capacity but the bms board lacks cell balancing and cus these cells are cheaper and may not have equal internal resistance they go out of balance soon. like in 200 to 300 cycles the pack would become unusable.
Thanks, that’s a good public announcement 📣
It is a pity there isn't a reputable battery maker that does aftermarket batteries, but with the highest capacity cells available at the time. The manufacturer will never update the cell capacities even if they keep making new batteries more than a decade after the computer model was released. (looking at you Lenovo).. Only thing left is to find a reputable receller, and even that can be difficult with the newest anti-counterfeit chips in the batteries.
YES. I have no problem with aftermarket batteries, it's just near impossible to tell which ones are reliable and which ones are junk. There are MILLIONS on the market.
You should further open each battery, reason being you'd be surprised as to how many will contain sand. I purchased some Battery Banks that contained several cells only 1 cell actually worked and the others were dark blue cover, like yours, and contained sand. If nothing else it might make a good follow up video... Cheers...
Interesting, that would go along with the 1hr run time. Altho, this would mean 3 cells are good (2000mAh) and the other 6 are sand barrels.
@@korishan yes I did mean one series when I said one so basically like you said 3 cells will work and 6 filled with sand. The very light ones should be sand...
LOL. Maybe I'll throw them all in the Opus testers and see what they say.
@@LithiumSolar That works too, of course ripping them apart would make for a better video... LOL... Cheers...
I have traced the discharge profile of what was supposed to be a 'new' 'original DELL' 97 Wh battery (where the 'new' was later clarified to mean 'original used but still in good health' 😮). I found a duration of about 1hour - 1 1/2 hours with a sharp transition at the end of said duration (irregardless of battery capacity - in one case the transition was at 62%, in another it was at 44%).
The profile is in a video of my chan that i will link below (because yt will probably delete the entire comment).
..aaaand yt deleted it.
Never once had a Counterfeit Medical Pack. I have seen some OEM packs, but they had Genuine LG cells in them.
That's because you have a solid supply stream :)
You should have opened the original battery you were replacing to show what cells it used.
Bought a second hand laptop from a actual company where i live and my battery wont take any charge and it turns off when ever i turn on my pc
when ever i went back they gave me a new battery and it had the same issue
so i opened it today and its just like this guy no label,unbranded cells
it voided any warranty i had but i learned something new about that company
That explains a lot.. I thought my laptop was broken, probably just a dud battery.
Thank you very much for this video!
Got a fake HP laptop battery and returned it to the supplier and got a refund. Of course, the seller keeps on denying that it is fake.
Unfortunately, there are so many on the market now that the only way to be absolutely sure it's genuine is to buy directly from HP, Dell, etc.
@@LithiumSolar true
I bought 6x cheep laptop batteries 3s 2p 5400 mAh. Tuned out it was 2s 2p 4000 mAh. Each cell marked 2000 mAh but the middle two cells were fake/dead short.
Ouch... Sorry :(
watching from India
nice work man 👍👍👍
I've been stung. I've got packs with wood dowel where there should have been batteries.
please help me out i have asus n552vw and i cant find a genuine battery for it from amazon or ebay
I got a ton of those battery packs that are genuine. I took apart a few but they all have LG or Samsung HV cells.
Not very useful for me and shouldn't be mixed with 4.2v cells as the discharge curve and nominal voltages are slightly different.
I have a HUGE box of those green LG HV cells. I'm not sure what to do with them lol. They don't seem to test well even if I test with 4.35V.
@@LithiumSolar I had a lot of those hvoltage cells. I charged them to 4.20v and did a cap check on them, and that number was what I wrote on the side before I stuck them in my diy power wall.
I did test them at 4.20V but I get bad numbers like 1600mAh on a cell that's supposed to be 2600mAh. Are you getting large discrepancies like that too? Most Samsungs or Sanyos that are rated for 2600mAh from packs in the same lot test easily 2400-2700mAh, so the only thing left to assume is that the LGs deteriorate faster for some reason.
@@LithiumSolar It depends on how old and how used up the hv cells are.
And how much more cap can a cell hold going from 4.20v to 4.3v, 100-300mah?
I never kept any tested cells under 1900mah
@@LithiumSolar Almost same results. got a ton of pink LG HV cells that give me 1800 to 2100 mAh when testing from 4.2v down to 2.8v. I don't think i'll be using any of those.
Either way i moved over to leaf cells for the time being due to ease of assembly. When I get more time i'll get back into 18650's to augment my leaf powerwall. lol
You should have done a capacity test on one or more of those cells for the sake of this video.
I still have the cells here. I put 4 of them in the Opus tester and will report back the capacities when they finish :)
I tested 8 of the blue cells at 1A and got 2122, 2067, 2009, 2016, 2077, 2119, 2161, 2054.
@@LithiumSolar . Not bad for a nock off pack. Doesn't really account for the short run time. Hmm?
@@E-BikingAdventures My thoughts exactly.
@@E-BikingAdventures Was my thought also, wonder if the wire was already loose, disconnecting some of the cells...
Hmmm. The 2nd battery you bought on Ebay could just be a much better quality counterfeit. You didn't mention how much you paid for it (first clue) or open it to see what type of cells were inside, like you did the 1st one you bought. Seems like an unfair comparison. As a buyer for a computer business, I've run into my share of counterfeit batteries and ac adapters. Some you can obviously tell from the outside, but some that you might think are totally original will surprise you when you pop them open. I've cut into several seriously good counterfeit adapters only to find the tiny wire gauge and lack of coaxial shielding a dead giveaway. Good job on the video - the weight thing is definitely a factor - especially in AC Adapters - but another very big clue you left out is the FIT and color/texture. Counterfeits will often fit poorly (or not at all) and have an off shade of color that you would never see in an original.
Except, counterfeits don't have the serial number on it nor the lot number sticker. Also, both of the Genuine batteries had Grey lettering next to the Blue Box with the Dell logo. The counterfeit has Blue lettering, which appears to be counterfeit indication still seen today.
No way to open your original Dell battery to replace the cells?
I thought about doing that but don't know that I could open it in a way that would go back together in a way that fit in the laptop and was safe to use.
It would be very hard to do cleanly. The shell is sonic welded together, basically the halves are fused together. The only way to do it cleaning would be a dremel and cutoff wheel. But that would take a lot of time, patience, and extreme care to not go too deep.
And then, even if that was successful, then comes the putting it back together again. I suppose you could use super glue, but it wouldn't be as strong as it was before.
On top of that, it might be possible that once the bms looses battery power, it completely shuts down. Without knowing which pins to short, or to activate externally, the battery would be a paperweight.
Bro, when you go for cheap shhhh, this happens. The statement is genuinely from my experience. Now you know. Have a nice day.
I know, I just don't know how to tell the genuine batteries from the fakes other than buying directly from Dell. A $50 could ust as likely be a fake than the $30 battery :/
Try to open battery its self, i think you will find sand. I so someone discoverd it before on youtube
my design capacity was 31000 mwh and now its 28000 mwh, and full charge capacity and design capacity are same now, its 28000 mwh, i dono how can design capacity change !
Where are you seeing this information? The BIOS diagnostics of your laptop?
@@LithiumSolar yes, and even battery report from cmd command
@@LithiumSolar from the CMD command im generating battery report and getting info there
How much was the good replacement?
I bought a fake Cannon camera battery. Instead of 3 x 18650 cells it only had 2!
I hope you got your money back! :(
god i wish there was more new oem laptop batteries that work properly instead of reverse engineered chinese knock offs that’ll probably explode in my laptop
There's just too much junk. The only way to be 100% certain it's genuine and safe is to buy directly from the manufactuer (Dell) or an authorized distributor.
The downvote is from the slimy eBay seller 😜
LOL or one of the other 10,000 slimy sellers 😡
I have a question.
I have an answer (maybe)
@@LithiumSolar have more than a question, do you have any social media account to message you?
1.nvsvc prevents restarting
Elara prevents restarting
2.slow touch pad when charging
3.I arrive 100% percentage, after many stops at some percentages
4.How to enable the shutdown sound and popup notification below the desktop with playing a sound.?
How many hours does an original battery (n5110) remain , if I am running a browser??
What's the weight of an original battery??
How do I prevent the seller to sell me a fake battery?
I just order battery from aliexpress its so express, 60-89 days to recieved the shipment 😂😂😂. The saller is not response when i asked for the shipping time, and when he ship it he answer me and telling me 60-89 days.
Image that after 60 days i got fake not working battery. So long ship.
China made the earth bad place.
When we will back to buy prodcuts made in usa or made in japan.
Just got my refrigerator made in usa , so good prodcuts i like it.
its only partially the fault of china. another half fault is of the smart people who try to spare few bucks and then end spending double..
my lesson: never shop on Ebay unless it is brand store
