I did some did some checking, and it seems that Watson is made by an outfit called the Gradus Group. They produce a lot of imaging and pro audio equipment, with 23 different brands. Watson is one of these, and is clearly Gradus power products labeled for B&H. I am sure that they make other brands for other large clients. (BTW, the Ruggard bag that many of us got from B&H with the 7DII is a Gradus product as well.)

EDIT: Well, it looks like everything Gradus makes may be sold only at B&H. I didn't check all 23 brands, but the dozen or so I did check are sold exclusively by B&H.

Where did you find a third party LP-E4n? Or are you using a Wasabi LP-E4 in your 1DX?

Sorry if that was a bit misleading! They are VHBW branded LP-E4 batteries bought on E Bay from Germany.
Their capacity is a bit less and Canon won't let them communicate with the camera but at 1/10th the price who cares? They work just fine.

Well, regardless, whether the voltage difference between the Genuine Canon LP-e6N, marked as 7.2 volts, and the Watson version marked at at 7.4 volts has any practical meaning, one thing is for certain. The two Watson batteries I have did not communicate remaining capacity accurately or consistently and therefore are useless to me. Since the Watson's sell for $39 USD, and the Canon OEM's sell for $62 USD, the difference of only $23 is not worth giving up the ability to accurately monitor the capacity. You're get killed by the prices over there. The LP-e4N sells for $164 here, or around £104 GBP. Even if you're including VAT you're still getting slammed. I could certainly understand your reasoning when you can save over £125 per battery. But for me $23, which is only around £15, simply isn't worth the hassle.

Good point. With the LP-E4 and LP-E4n batteries the price difference is huge! As you say for a few dollars extra for a battery that communicates then there is less of an incentive to go non OEM.
P.S. We do get hit around the head with prices over here - but not all the time! What I paid for my 1DX and Gitzo tripods made the USA look a bit pricey at the time.
Grey imports put us more in line with international prices which is great but it hurts the high street retailers which we depend on - you just can't win!

The tech had some bologna for lunch and was trying to feed you what was left over. ;-)a

The individual cells (two) in the battery pack can be referred to as either 3.6 or 3.7 volts nominal. The fully charged voltage of an individual cell is 4.2 volts regardless of the nominal voltage, 8.4 volts when combined in series. The only real difference might be capacity. The voltages are the same.

It also depends on whether the cells are balanced; this will also affect the capacity somewhat. If the cells aren't balanced, the battery will show 'full' before both cells are at capacity and it will shorten the lifetime of the pack. But this will only reduce the available voltage; as has been discussed, it's the battery chemistry which matters. Modern STK/Wasabi cells work perfectly in my cameras all the way up to my 7D2.

That said, the ONLY battery of the 8 LP-E6 I've purchased since 2011 which has shown any degradation in performance has been one of my original Canon OEM packs. None of the STK units has shown any reduction in performance whatsoever, despite being used more often than the OEMs. Based on the huge price discrepancy and utter reliability, STK has my business for the foreseeable future.

I use Canon batteries till the camera is out of warranty. I purchased an extra Canon battery for my 7D2 and rotate between them. I don't want to do anything during the first year to give Canon a reason to reject a warranty claim.

I use Stering batteries in my 40D and when I replace the 7D2 batteries I'll go back to them.

If you register the serial numbers of the batteries, it will be clear that some of the numbers stored in your camera are not associated with Canon batteries. Some of my 3rd-party batteries' serial numbers don't even have the same number of digits as does the Canon battery. If you did not delete this battery information before sending the camera to Canon for warranty service, they could easily determine that you had used non-Canon batteries. Of course, if you did delete this info, they would have no way of knowing.

Good to know. I wasn't aware that use of 3rd party/non-Canon batteries voids Canon's warranty.

I doubt that it would, per se, but if there was any damage that might have been caused by a battery problem, and they knew you had used 3rd-party batteries....

I'm not sure what such damage might be, and I guess I don't worry about it, as 75% of my batteries are 3rd-party.;-)a

My feeling is why take a chance with a new camera? If Canon asks, I want to be able to say, "Yes, I only used Canon batteries in the camera."

This is how I started this thread - there are no Canon batteries. Canon batteries are made by Panasonic.

... My opinion (unsupported by evidence) is that Canon sources their OEM batteries with lower capacity in hope of increasing reliability. However, the only battery I've acquired since 2008 which has exhibited any problems at all is my 7D OEM battery, so...

Funny you should say that. The only that died on me in the last few years was the one that came with my 7D.

As for fake non OEM batteries you get both Duracell and Energizer fakes. They are worldwide brands, and as such command a premium price in high street store chains. Fakes are out there, so I bought a Duracell For my 600D direct from Amazon, and a Hahnel for my Amazon too. I won't touch fulfilled by Amazon, as third party sellers ship to amazon for redistribution. So far I've been Ok.

I never checked the batteries, but tried to do it today. Out of seven LP-E4 batteries that I had, three are Canon, four - Watson and no-name. Only two Canon batteries showed degradation. All others are fine.
