Where do you get the freshest LP-E6P?
The NYC stores have not been the most reliable with Canon batteries, sometimes a year old or so.
Thanks.

These batteries were introduced on July 2024 when the R5ii was announced. I would either buy from Canon, B&H who have high turnaround to guarantee freshness.

Does the date really matter that much? As long as they have full capacity and recharge fine, there shouldn't be much of an issue.
Ideally that would be the case, but the Canon LP-E6 series just go from three green to two green to one red far too soon. I just tested about 15 batteries and all but one dated 2022 and older are in the red zone. All 5 of my LP-E6P are from the 2024-05 release batch and those are all two green, so will be going down to red fairly soon.

I've been curious about this, though - have you noticed any significant decrease in performance, or are you just looking at the three squares?

You seem to have such bad luck with every piece of camera gear you touch. Have you considered trying a new hobby?
There is no luck here, just cell, BMS, and battery characteristics. I've been charging batteries since 6 and designing chargers since a teenager. It's fascinating really. Maybe I'm lazy at this age, need to get tools and open up the batteries without creating disasters.

In your experience, what would be the internal change within the battery that causes the 'health' reduction; three to two to one bar?
I have one LP-E6NH that is now at one bar, but otherwise seems to work OK, though I have not done a rigorous comparison. But all of the Canon batteries I have no longer charge to 100%; instead to 100, such as 98%, etc. Yet all of the Neewer LP-E6NH clones I have charge to and hold 100% seemingly indefinitely. And I've owned those as long as the Canons. But they don't quite last as long as the Canon NH batteries, as has been discussed in past threads.
I need to find the equipment I used in 2024, but there is a difference of quite a lot on the 2-wire chargers.
I want to run various tests with older and newer P batteries to figure out what I can.
In Dec. there will be a cold zone and I want to be prepared. I'd like to go with a 2-wire for that trip.
