Genuine Or Counterfeit BP-511A Battery?

Peter J , Feb 20, 2010; 04:13 a.m.

I purchased two "100% brand new high quality Canon BP-511A Li-Ion Battery Pack(s)" from here: (link)

The photo below shows the front and back of the two packages. Both packages had different instruction sheets shown. I have shown on the left and centre two OEM Canon batteries. The battery on the right is from the eBay auction site. The left battery cover belongs to one of the OEM batteries. The right battery cover without the battery cutout belongs to the battery from the auction site.

I am waiting for the seller to explain the differences in the battery shown in the photos on the auction site and the one I received.

I will post two close up photos below this post. Please tell me if the eBay battery is counterfeit.

Here is a closer view of the two genuine Canon BP-511A's and the eBay BP-511A.

Here is a close up of the eBay BP-511A. Notice the "Europe Only" label?

Is this a counterfeit battery?

First off, great shots.
The fact it says Japan and comes in Canon pkg is the holy grail for me.
If it had said China, well not much needs to be said there.
Back when I started with the new 30D in 05, and other models needing the same battery, I purchased a case of BP511 batteries 2000mAh.
I forget the source off hand, but will update if known.
Funny, on the back of the battery it says Premium cells from Japan, Made in China.
They have performed better than the original Canon's that died while in Europe. I was a bit upset.
The Europe only label, is somewhat confusing. Like it was charger voltage specific. Doubtful. Decent price too. I noticed they are 1390mAh.

Not counterfeit, but aftermarket 511A batteries.....I've had nothing but good results.
Several suppliers. I just wish there was an aftermarket version of the one for the MK5D2/7D
(can't think of the p/n).

I bought an additional set from ebay, and have had the same results as the batteries that came with my 50D. No difference even though they were packaged and marked different.

I got mine from SterlingTEK, 20 to a case.

They look like counterfeit to me, the poor printing on the blue label is a give away and it doesn't have a CE marking.


These, if they are non genuine (and I'd put money on that), are counterfeit, they are not just aftermarket batteries, they are labeled and packaged with the intention to decieve. Nobody should get too hung up on labeled and non labeled batteries etc but if the aftermarket ones are labeled with the intention to pass off as genuine then that makes them counterfeit.

I choose to use aftermarket, but that is my choice, if I wanted to pay a premium for OEM ones then I'd be annoyed if I didn't get them.

Thanks for your replies.

Phil Trites : I needed to show detail and used my Canon EF 100mm f/2.8 Macro USM. The "Min. 1300 mAh 9.7 Wh" also was perplexing.

Bill Morrow : I have a couple of older Optex and Powwer aftermarket batteries. The Optex is 1400 mAh and is made in China. The Powwer (I believe is made by Sterling) is 1800 mAh and is also made in China. Both batteries are about 3 years old and currently are not holding a charge. My first OEM made in Japan battery from 2007 is still holding it's charge.

John Slaughterbeck : Do you remember the eBay seller where you purchased from and for how much?

Scott Ferris : I agree. The batteries in question are missing the "CE" listing. The aforementioned Optex and Powwer batteries are labeled "CE" which gives me more peace of mind.

To conclude. Since the batteries are not labeled "CE ", I will discontinue their use because of the increased probability of the batteries melting or exploding in the OEM charger. The probability of the batteries leaking inside my OEM vertical grip and worse, my 5D, is also high. I paid less than $16 for each battery. No sense shipping them back for a refund. The cost of shipping (and bubble envelope) will not make it worthwhile. Lesson learned.

I've purchased and used both originals and aftermarket. The aftermarket seem to work as well as the originals. I totally agree with Scott as to your situation. If you were misled into thinking they were the real thing I'd be more than annoyed.
