UPDATE: Thanks to all who answered. I am convinced these will work. No need to have any more replies, but feel free if you wish. I want STK to provide the firmware version that these batteries have been tested to work on (not just work, but...

I used both firmwares 1.1.2 and 1.1.3 and they work fine on both. There was not a change in performance to either firmwares that we noticed during use. During our last event, my buddy was using the 6D with the 1.1.2 and I was using another with the 1.1.3, using the STK batteries - we both basically had to change batteries close to the same time.

I had to buy the STK charger as my cannon charger did not work. The new STK battery charged up fine with the ST K charger, the battery only took 3 charge ups and then failed. Returned battery and think I will get a new battery from Cannon. The orginal cannon battery lasted a very long time.

I have a 6D, that firmware, and STK batteries, and they work fine. Your Canon charger however, will not charge them properly. I got a free charger from STK that works with STK and Canon batteries. Just send them an email and they will get you one.

yes they work. i would recommend buying the amazon rechargeable batteries and not some generic radio shack type of batteries. i only say that because i actually own rechargeable batteries from radio shack and they lasted about 20 minutes running a game. angrily, i went and ordered the amazon rechargeable batteries (white, AAA, made in japan) and i haven't charged them in about 3 hours of playing time. buy these: AmazonBasics AAA Rechargeable Batteries (8-Pack) Pre-charged

Thanks for the link, Repro. I'm in the process of ordering a battery as I type this. According to the reviews of the battery, all zs3 owners/reviewers are reporting success with this battery no matter what firmware the camera has. Thanks again for the info.

They are not listed, but I don't see why not. They will physically fit and the voltage and mah specs are similar to other listed batteries. You should probably confirm with the manufacturer though.

Update: The description now says that these batteries *do* have NFC compatibility. Not sure if the ones that had already sold have NFC as well (though I haven't seen any errors with my batteries to suggest there isn't NFC).

literally, yes. But if you have rechargeable batteries, why not give them a try. If they're 1.5V, they ought to work.

I am unsure. The batteries that I ordered for my phones work . Look on the internet to see is they are comparable .

I think that they would work, can always give a try and return if they dont work. Hope this helps.

Yes they will. I bought these for mine and turned out the UPS was defective. Couldn't return the batteries cause the vendor would not take them back, so I'm stuck with them.

Yes, they work great. They will give about double the run time of a stock battery.

I just Purchased two STK LP-E6 batteries for my Canon 7D Markll, I have yet to use them but they fit the charger and are identical to the one that came with the camera!

I have the same camera and these batteries worked fine - don't know what firmware or firmware version would have to do with batteries??

I want to know the answer to this as well. Can we use the OEM charger for these batteries? Thanks!

Sure, it should work fine. I had a problem with 2 STK EN-EL-3e batteries. One would not charge right out of the box and the other took a 3/4 charge the first time then it would not take any charge after that. It seemed strange.

I have used these batteries on my AX33 and they work fine. I think the AX33's firmware does not perform a check for the battery type. Panasonic took a lot of heat for this sort of thing a few years ago - and ultimately took out the battery check. I think most manufacturers learned their lesson from that.
