BTY AA Nimh Batteries
Aug 6, 2008 01:11 AM
The BTY brand of Nimh batteries that are being sold on ebay by various sellers (most from Hong Kong) are not very good. The AA batteries are supposed to be 2500 mah but are in fact usually about 800 mah (or less) and are not useful in digital cameras (or anything else for that matter). I have purchased a total of 48 of the BTY 2500 batteries and so far have only 4 out of the 48 that are even usable. Those 4 are about 1500 mah (still nowhere near the advertised 2500 mah). If you are tempted to buy the BTY batteries I suggest that you charge and test them immediately upon receipt and return them at once if they are no good. It's a hassle to return them if you have to send them back to Hong Kong. Holliday 080806

Ebay is at fault here. If they want, they can easily clamp down on sellers of fake and fraudulent merchandise. However, they rather get their share of profits from sales of fake products to gullible people. Those who know how to test batteries or have the equipment to do so are a tiny minority of the population. The battery scam therefore continues..

 

I just bought some of these batteries - advertised as 3000mAh. Turns out they average 300mAh. Seller offered a partial refund. Asked for a full refund. Opened a dispute with ebay as well. If all of us take such action, the incentive to advertise/sell fake products will go away (since there is no money - only loss to be made by seller).

 

There also needs to be a way to give a major ratings hit to those who knowingly sell bad products (instead of calling them "Top Rated" - like mine was).

Where I think people are going wrong with these batteries is that they are trying to fast charge them in, for example, one hour chargers. Some rechargeable batteries even some of those those of mainstream brands are not suitable for fast charging. So try a slow (overnight) trickle charger. That's why the advice coming from Chinese sellers is to buy one of their chargers.

 

I will however agree that the batteries have a lot less capacity than that stated on the batteries. But they are still a lot cheaper than mainstream 300 mAh rechargeable batteries for running things like clocks and remote controls.

 

I suppose it is possible that the batteries sent to United Kingdom where I live are different to those sent to U.S.A. but I really don't think so.

 

Lastly, anyone who tries to run a camera or flashgun on a cheap battery has to be incredibly naive, silly or stupid or even all three at the same time.

 

btw I'm on the U.S.A. ebay because I sometimes buy from American sellers who mail to U.K. Right now searching for a new RFID blocking Aluma wallet :)

I recently got "BTY AAA batteries" for my phones and when i installed them the phones registered a message that the batteries were no good!   Had to remove them from all 5 phones and put back the old ones until new ones come..........methinks that you get what you pay for......these were $4 fo 12 batteries.........but I did contact the seller and was refunded the full amount.  I would not bother with these batteries again......not worth the hassle.

Re: BTY AA Nimh Batteries - SCAM !!!
May 8, 2012 03:03 AM

The BTY and the other no name brand honk kong/china red, green or yellow batteries are the worst rechargable batteries you can buy, I tested them and they gave me between 90-150mah instead of 3000mah. It's a SCAM, please avoid them at all cost!

Another one here seduced & scammed by these cheap BTY batteries

 

initially I only had a cheap multimeter to test the batteries so got conned into thinking they were OK because the actual voltage they give out initially is correct

 

Only realised there was a problem much later on when I actually tried to use them - by this time I had bought at least 60 AA & AAAs & it was too late realistically to try to get a refund

 

I have since bough a proper charger/tester & like others have found capacities of most of the  AAA's  to be between 100 & 200 mAh ( some are even worse than this though )

 

The tester I bought was this one whih is just a rebranded La Crosse BC-700

I found this thread while searching about on how best to file a claim against these sellers of misrepresented NiMh batteries.

 

I got a bunch of these batteries from another seller "ichiban_shop" (http://www.ebay.com/itm/230719946570?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649), they are of a different brand.

 

Running them through my Lacrosse chargers revealed that they are not quite close to the 2800 mAh batteries as advertised:

Some of my 5 year old very well used and worn out batteries still deliver better capacity than this. What should be the best way to go about filing a dispute?

To wshyang: As you can see, we have been complaining about these trash/ripoff battery sellers since early 2008 and ebay still allows these vendors to get away with it!

To complain, click on "Customer Support/Resolution Center/ and click on the bullet "I received an item that does not match the seller's description" and follow the directions.  Holliday 120623.

unfortunately purchased 4 packs of 4 3000mah bty rechargeables- take one picture with pentax dl with flash and message says batteries depleted! Absolutely useless.  coming to these reviews and thankfully find my experiences are quite normal.  made me very sceptical of all rechargeables for a few moments.  reckon they stamped an extra zero on the capacity!

I am confused about some of the various (and numerous) complaints about the BTY brand NiMh batteries (AA size):  Is the problem that people are buying FAKE BTY batteries from Hong Kong (power output ratings overstated, wear out almost immediately, etc.)  OR: is the BTY company of (China) a company that is making a lousy product?  If their product is so lousy, why do they have such a tremendous distribution all over the world?  Also, I noticed different battery labelling/model numbers of the 3000mah batteries: some are blue/silver model HR6, some are a newer green/white label model AA3000, another with green/gold label, etc. Are there differences in quality between these different "models" of battery, or is it the same battery with a different labelling? If I buy from an AMERICAN dealer, will I get the "genuine" battery?  Thanks for any input!

I am going to answer my own question: After 2 days of ownership, I cannot get two of the four new "AA" NiMH batteries to fully charge (at a rate of (600ma). Also, after cooling off for several hours, and putting them back in the charger, all four batteries lost 25 to 50% of their charge WITHOUT any usage!  They were then placed in a simple transistor radio and went dead in less than 30 minutes of play. DO NOT BUY THESE BATTERIES!!!  These were GENUINE BTY batteries in the FACTORY PACKAGING (I checked this out). They were not the "Hong Kong knockoffs"!  This is an extremely low quality product, and ANY money you spend on them is wasted!  I speak from experience. Thank you for reading this.

ANY no-name Nimh Batteries

Add me to this very long list of buyers who just don't understand how Ebay allows these well-proven fraudulent descriptions to continue. 

 

I suspect that the vast majority of buyers pop the batteries in their dumb chargers and find that the batteries make their toys work, so leave positive feedback based primarily on cost and shipping time. 

 

If the vast majority of buyers even notice that their toys don't operate as long as they should, it would likely be after the feedback has been left, and I doubt there is anything that can be done.

 

Like many, I believed the description when it said 3000mAh.  Before they arrived, I did some research and discovered this long-standing issue.

 

My research also led me to buy an advanced charger-analyser.  I spent about $80, which I would have considered outrageous before I did my research.  Now I think it saves me money.

 

I had my analyser waiting when the batteries arrived.  Originally, their capacity was about 200mAh, but after using the "break-in" conditioning mode on my analyser, their capacity climbed to between 400-500, and plateaued there.

 

Luckily, I was still within the "Feedback window of opportunity".  I advised the seller that the item was "not as described" and requested a refund.

 

Over a series of emails, the seller:

- suggested I charge them slowly

-suggested it might be due to long shipping time

-suggested it might be due to them getting damp during shipping

-offered a partial refund

-offered a full refund in exhange for positive feedback

 

In my series of responses, I said:

- my charger-analyser showed their capacity as 400-500mAh

- I requested either the seller refund or send batteries that actually were 3000mAh

- long shipping time shouldn't affect batteries supposed to last for years and multiple dis/charges

- the batteries seemed dry when they arrived

- their negative feedback indicated that this was a consistent complaint, indicating the seller knew the item was "not as described"

- finally, since the deadline for contacting the resolution centers was approaching, to within 24 hours, either issue full refund or ship real 3000mAh batteries (in which case I would likely have to open claims with the resolution centers, but be prepared to abandon them once real 3000mAh batteries arrived).

- that I could rate highly on communication, shipping time and charges, but not description

- that I have never complained about an Ebay purchase, and have 100% positive feedback as a buyer.

 

The seller issued a full refund.

 

I left negative feedback on description, positive on communication and shipping.

 

The cost was really cheap, the refund didn't hardly matter, but I wanted to maintain my ability to leave feedback that would explain the situation.  Unfortunately, one isn't able to say much in feedback.

 

I was lucky that I got educated before the batteries arrived.  Otherwise I was just another unknowledgable consumer who wouldn't have noticed a problem until too late.

 

I doubt that my negative feedback or this lengthy rant will change anything:  buyers will look at the high-mAh description, the very high positive feedback rating and buy.

 

That's why I really feel that this is a case where the history of fraud is so well-documented and repeated that Ebay should exercise some kind of control over the situation.

 

Does anyone know a way to get Ebay to listen?

I've come to the conclusion that ebay is not too worried about sellers ripping-off buyers as long as ebay can make money out of the transactions.

 

If they really cared, they would have provided some method for filing complaints after the resolution center's deadline in cases like this.

Hello users, get real. It is impossible to have an AAA rechargeable battery to discharge 1800 Amp or 1000 Amp in an hour. Theoretically, If an AAA can discharge 500 Amp is already an excellent one. Don't forget the efficient factor will also lower this. This also apply to AA battery (AA battery may perform a little bit better than AAA).

 

So do not believe you can have 1800mAH on an AAA or AA rechargeable battery.

I cycled 16 of them and the average was around 200 mA

 

Quite a scam.  The average person is not necessarily going to have the equipment for proper testing.

Few years ago I bought here on eBay from a couple of different sellers, all from Hong Kong, several AAA 1200 mAh and AA 2500 mAh.

They all have very low capacity, a fraction of the advertised and in comparison with known brand batteries!

Note that the AA batteries are NOT labelled "2500 mAh",

it has only "2500" written on it, 2500 what... meters? kilo? years?

I see these days one can find also 3000 "mAh", but they do also lack the magic letters "mAh", beware!!

Those figures alone means NOTHING, BTY batteries are pure fraud!

I support the comments that the AA bty batteries only about 500 mah capacity instead of the advertised 3000 mah's. I have also purchased a plain no name battery with similar results.

The weight of these batteries as mentioned on another is a good indicator of quality with good batteries weighing about 25 grams while the others are less than 20 grams

Add AA Zeikos 2900mAh (Sold as "UltraPower Rechargeable Batteries Battery 2900mah").  I tested these to ~660mAh.  They don't weigh much compared to name brand 2000mAh batteries.  I am sending them back, read some reviews on Powerex 2700mAh, they seem to be the real McCoy...  They cost about 2x, but should have ~5x capacity.  The Zeikos also had an internal resistance of ~0.8 ohms.  These would be horrible for almost any camera/flash  or other high discharge application.  We will see how the Powerexgo.  The pathetic test results for the Zeikos is shown below.

Well I got stung last week also, a pack of 12 batteries, tested 8 so far they all average about 200mAH. Additionally they only hold charge for a couple of days. 

I met this once before a few years back, some supposed 2800mAH batteries, that time I cut one open to investigate, they turned out to be normal primary cells.
