According to this aftermarket batteries will not work.

Not surprising since the R52 is gimped even with older OEM batteries. Right now there are no aftermarket "P" batteries so kind of a moot point, though I only use OEM batteries anyway b/c I've never had a great experience with 3rd party batteries -- they are always short-lived and have less shooting power, esp with high FPS. We'll have to see if 3rd party "P" batteries come out in the coming months, but the bigger question to me is: will a 3rd party R5II grip be possible. I do usually buy a cheaper 3rd party grip b/c I don't use grips often.

I saw that and was bummed - I have a stack of 3rd party batteries for my R5, and was hoping I could use them in my R5MII until some good aftermarket P batteries start coming out. I ordered a pair of extra Canon P batteries also, now I need to decide if I should grab another pair...

Agree that this is not surprising. Many of the R5II's new features require the new higher voltage batteries to work and third parties will need time to reverse engineer and copy the chip protocol.
Anyones stash of OEM or third party batteries for anything prior to the R5II is SOOL if they need/want the latest new features.

grab them while you can if you want to use Preshoot - they are low in availability. My dealer ordered 60 and got 8.

I wonder if the camera is designed to reject non canon batteries to force you to buy theirs.

The non-Canon battery makers will adapt.

Of course. The argument is it's for the consumer's own good to protect them from inferior counterfeits.

I just wonder of Canon made their P battery chips harder to clone in order to close whatever loopholes third parties may have exploited until now with the older battery versions.

Since Canon went through the effort to upgrade the batteries, I would have liked to have seen a redesigned charger that is smaller and could also be powered from USB power banks or the various GaN chargers now available, and be able to recharge batteries faster.

Canon made different batteries for the R5 too, and the Neewer versions I use work just fine.

I only use OEM batteries, but when the R5 first came out you couldn’t find any spares. Thank fully many people smarter than me did all kinds of testing on alternative manufacturers and deemed the Neewer performance to be the same as the Canon so I purchased a two pack with the double charger and they performed the same as the Canon. Following a firmware upgrade my Neewer would no longer work. I am surprised to find people can still use them. Hopefully Canon will have a supply of the new batteries for the R5 MK II a single battery will not let me take the camera when available on a new trip.

Dave, it's probable that your batch of Neewer LP-E6NH are an older version, which if you bought them around 2018, wouldn't be surprising. I have six of them purchased between fall 2022 and earlier this year. They're difficult to resist when they're discounted to ~$40 CAD for two with charger on Amazon.

All of them work fine with my R6 and R6II.

Three of my four Canon batteries bought in fall 2022 now show only two bars health, but I still get more shutter actuations from them than the Neewer (when I use one of each in the grip), which still show three bars and always charge to 100% (the Canons now typically top out at 96-98%). When all were new, both Canon and Neewer, even then I got about 15% more actuations with the Canons when both reported the same/similar capacity level. I do think there is a difference, to the advantage of the Canon batteries, but considering I can buy six Neewer for slightly more than one Canon, and that I have not had any failures with the Neewer, it's difficult to justify more of the OEMs at this point for my set up. That said, if I was an R5II early adopter, I'd definitely get a few more of the new P batteries.

For those coming from the R5, the R5II should get more shots per charge, which would mean the need for fewer spares. That was definitely my experience between the R6 and R6II. And my brief time with the R5 gave me the impression that it was somewhat more power hungry than the R6...

I'm pretty sure they're the same voltage, but higher current. Though this isn't 100% clear from the marketing materials.

ETA: I found something that said it's 8.4 volts, which is higher voltage than the earlier generations (7.2V).

The LP-E6P battery, when compared to previous battery versions, features higher continuous power and two-times the amperage

https://www.usa.canon.com/newsroom/2024/20240717-camera

Funny enough there's a page on adafruit that briefly talks about li-ion batteries.

You may also run across 4.1V/3.6V batteries. These are older than 4.2V/3.7V - they use a slightly different chemistry and you'll see the 3.6V marking on the cell.

https://learn.adafruit.com/li-ion-and-lipoly-batteries/voltages

So it's likely the 7.2V Li-ion batteries that are in current Canon batteries use an older technology, and these new batteries move up to the 3.7v x 2 = 7.4V nominal voltages.

So it's a very slight difference in nominal voltage, and peak voltage would go from 8.2 to 8.4V like moondigger found.

EDIT: Confirmed that the old 7.2V nominal batteries are 8.2V peak. (Just checked a fully charged battery with a multi meter)

I made the video in the OP. I did not have any issues with aftermarket batteries when the R5 was released. I only have the aftermarket batteries for my edelkrone items, as I use genuine batteries for the body as they tend to last longer charge wise for me.

For those interested focus camera has the new batteries in stock. I got a couple from there and have them on hand already.

I tried a few different brands of 3rd party batteries and as the video confirms the R5II won't turn on or show any icons in the top display. I'm glad I saw this thread as I was able to dig out several old batteries I forgot I had in the drawer and give them to a buddy who can use them.

This makes sense; I should have realized earlier that I was incorrectly comparing the nominal voltage rating of the older batteries with the peak voltage of the new ones.

I also should have remembered that lithium ion chemistry can support a range of peak voltages, depending on slight differences in chemistry and (significantly) on where the charging circuit cuts off. I suspect these new "P" batteries will only charge to 8.2 V in the older Canon chargers, for that reason.

What do you mean with "older Canon chargers"? As far as I understand it is the same charger fpr R5II and R5.

Canon has stated the new batteries are compatible with older chargers.

Considering they stated the 1DXII battery, the new LP-E19 (as used in 1DXIII and R3 also) was not compatible with the older chargers, I think they would:
1/ Not state the new R5II batteries are compatible with old chargers if they are not
2/ State a new charger is needed

They also stated older batteries could be charged in the new charger, but they would not be charged to full capacity. (The 1 series / R3 batteries)

I thought I read that the R5 Mark II came with a different model charger. I don't have an R5 Mark II, so I can't confirm this.
