File PayPal dispute product not as described. Battery capacity is not as described. Take pictures of the capacity even. You could show hjks test link. EBay usually sides with the buyer. I wouldn’t have anymore communication outside the dispute if you are going to go that route.
But they arnt horrible batteries. You’ll still get a good runtime from them. You could just leave negative feedback on the seller and go on with life lessoned learned.
It sounds like you arnt the first person the seller has had issues with. Almost seems standoffish. In the end its up to you. Negative feedback with fake capacity batteries review hurts sellers.
If you want to reply I’d say I’m not using a cheap battery tester, or a cheap charger. I didn’t get a mah reading in seconds. I ran 3 test and takes several hours each and they are below capacity. Here is even a more in depth test of these batteries. And send him some of hjks graphs. I have the equipment to check batteries. And 100mah would have been OK but not 1000mah difference. You can refund me or I’ll open a dispute and let eBay deal with it. Since they are here to protect me against sellers like you
I made an error stating that I discharge at 1 amp with the Litokala Lii-500. It charges at 1 amp, but only discharges at 500 milliamps. My hobby charger on the other hand can discharge up to 7 amps. Sorry for the confusion.
The seller is talking out of his backside & either doesn”t know what he is on about or is being immediately aggressive & negative because he has had other complaints about these cells capacity.
You do not need a $1000 oscilliscope to get a capacity reading of within a hundred or 200ma of accurate & you are 1000 ma different.
A Lii-500, Opus etc will give a close enough reading to show if the capacity claim is fake or not.
According to his statement then a SkyRC MC3000 is also a cheap non decent charger that cannot be used to test capacity :person_facepalming:
From the sellers aggressive reply it does sound as if you are not the first person to pull him up on his capacity claims.
If you do decide to keep the cells though what feedback are you going to give as if you give honest feedback then his communication is poor aggressive & arrogant & the product is not as advertised.
Up to you which way you go.
They are reasonably good cells but 1000mah less than claimed.
You could just put it down to experience & keep them or involve paypal as from his reply he is not willing to do anything to put the matter right unless you pay the return shipping.
EDIT: Just re-read your post, I am not familiar with the accuracy of the 2 chargers you mention.
Are they normally reasonably accurate for capacity testing ?
Yes, they seem to be. They always agree with he results others post here and they agree with each other.
Want to hear something funny? I actually do have an $1200.00 oscilloscope in the garage that I picked up in an estate sale years ago. I just haven’t really taken the time to learn how to use it :person_facepalming:
Well it is really up to you then.
The seller is being an arse IMO.
I personally would not be happy buying 5200mah rated cells & finding they are actually 1000mah less.
However other than some really really poor “fire” cells I bought years ago before I knew any better & some “fire” cells that have come supplied with lights I have always bought cells that have matched claims.
In the case of 26650”s I have bought cells that actually exceed capacity claims (Liitokala & Thorfire 26650”s :+1: ).
I always read cell reviews on here & on HKJ”s site before buying :+1:
So the ball is in your court so to speak
BTW HJK only got 4205ma capacity out of them at just 200ma discharge rate, according to the seller he obviously doesn”t know what he is on about either Test of AWT IMR26650 5200mAh (Red) 2015
Yeah, I messed up. If I end up taking the hit here it’s my fault to the degree that I was not as educated on where good batteries come from.
I’m a bit wiser now.
IMR and GearBest are where most of my batts come from now. But I’m reading HKJ’s and others reviews first from now on also.
I strongly advise everyone from using this seller. In additional messages he called me a jerk and refuses to take the batteries back without me paying the return shipping. All I wanted is what I paid for….5200mAh batteries. He told me I should be happy since “4200mAh is plenty”…. lmao.
I’ll ask ebay to step in. If they won’t help it’s probably $5.00 to send them back….may as well keep them.
Here is my experience with him over the last 5 years! When everything is going great, your happy and he is happy, no problems. As soon as you bring up a valid issue he becomes arrogant and uncooperative.
What an ASS* to tell you that you should be satisfied w/ 4200mAh!!
He probably does NOT get too many customers like us that will test the products and know what were talking about. The average Joe would not know the difference.
I would fight for my money back just based on PRINCIPLE.
I have bought one thing off of him since my incident w/ him ~ 3 years ago. The only reason I bought these Vappower 26650 was because they were highly recommended and I was in a pinch!
Good luck to you.
EDIT: I WOULD HIGHLY RECOMMEND MY HOMETOWN DEALER LIIONWHOLESALE.COM AND ILLUMN FOR BATTERIES IN THE FUTURE. MY HOMETOWN DEALER CARRIES ALL THE TOP BRANDS AT A VERY REASONABLE PRICE.ILLUMN HAS A BIGGER SELECTION.
Oscilloscope for $1000 or $10000 cannot be used to measure battery capacity. The best is professional battery tester or electronic load.
Cheap chargers may not be that precise, but most chargers are within 10%.
Yeah…he even called ME a jerk for wanting the 5200mAh as advertised, when after all 4200mAh was “pretty good”.
He actually said I ordered them just to return them . I honestly have no idea where he came up with that.
Maybe he thinks I’m another buyer he wronged trying to get back at him? (not the case).
VERY unusual ebay experience. It’s rare that someone is that abusive and one sided.
It’s not like you can’t find real 5200mAh batteries for less than $11.00 per cell right?
I have a hard time believing he is not aware that they are actually 4200mAh batteries.
You know, if he had been professional, admitted the situation, maybe offered a few bucks back for compensation I would have accepted and moved on.
The batteries aren’t bad, they’re just not 5200mAh as advertised and I wanted 5200mAh batteries for my L6.
I can get 5000mAh batteries for $5.00 per cell from GearBest. Why pay $11.95 ea for 4200mAh cells?
But I wasn’t aware of that when I ordered these. And I am not returning them because of that. It’s the discrepancy between advertised and actual capacity.
1000mAh IS a lot of difference.
All said, he did, finally, this morning accept the return and provided a return label.
I almost feel bad for the guy as he seems to have crossed other people and is getting tangled in his own web.
I do not intend to leave him any feedback at all good or bad. I think he thought I was someone he had dealt with before at this point.
This is why honesty, whether you are selling or buying, is always the best policy. Never advertise what you can’t deliver and never buy without honest intent.
When doing business, treat others as you would like to be treated whether buying or selling is my standard practice.
Buying just to “get back” at an ebay seller is immature, dishonest, vindictive and a waste of everyone’s time. Just deal honestly all the way.
They had significantly different discharge capacities. I measured the discharge capacity 3 times on the pair and they consistently tested 243mAh difference in capacity.
Their purpose was to be used in series in my Convoy L6.
This much difference in capacity between cells in series in a high discharge device could lead to trouble I believe.
Not sure if this is a systemic issue with all AWT batteries or just these but I would be hesitant to purchase AWT cells again especially for a series application.
200mah wouldn’t have caused any issues in series. Not when 4000 is there. There was a guy on YouTube running a l6 or s70 with one 26650 and one 18650 in series. Which is got a nice chewing out in the comments. But 200mah difference is no where near a danger zone
HKJ also measured different capacities for his two cells.
Non-capacity-matched cells in series can be a problem. The discharge rate is not so important; it’s at the end of discharge when this becomes a problem. One cell can become over discharged when the other is not. Most people don’t ever take the light down to the last 300mAh, so it’s usually not a problem in practice. But of course you’d prefer the cells to be matched.
This is what I had read here. I also “doubt” I would ever run my flashlight batteries that low but….since there are many lower priced options out there like LiitoKala’s that seem to be higher capacity, better matched AND lower priced….it seems to be an obvious choice.
Wish I had known about those and HKJ’s test before I ordered them.
