With my Sony batteries, not ever showing the charger light going off is a sign of a failing battery.
I had pulled the BM off the Canon charger when it was still blinking and it said 100%. I then put it back on the charger and about 10mins later the light went green indicating it was done charging. So as long as my next few charges go to 100% I won't be worried about the batteries or the charger.
I'll have my dual RAVPower USB charger next week anyways. I have one of those for my Sony and Nikon kits also and they are a nice way to do two batteries at once and it has saved my butt in the field where I was able to charge up off of my USB Powerbank.
I've been conducting a test on a bunch of NH batteries using a Dolgin charger that draws them down to 0 in order to measure actual MAH capacity, then charges them up again. I'm cycling them through the cameras and into that Dolgin and printing stickers to put on the batteries so that in a few months I can write up a review of it as compared to the other LPE6 range in terms of power fall-off over time/charges. I think I'm going to need another half year of data to get a good line on what the fit curve really looks like, allowing us to predict when things'll go bad in the future. I'm up to about 50 data points, but that's across a lot of batteries, so it'll be a while before the curve becomes evident.
The only things I can reveal at this point is that the battery chemistry itself is likely different than the other LPE6s, and that they do indeed appear to be starting down a curve of reduced capacity over time (but nice and slowly).
The reason why I say all that is that I've had a few of the batteries give me a lame first charge. One I charged today went from 1810 effective MAH last week to 2010 MAH a few days ago, then today down to 2008 MAH today. None of the batteries that were lame initial charges (1/4 of them) seemed to show any less capacity once they were broken in.
My BigMike's (BM) charger was able to charge the Canon LP-E6NH to 100%.
Oddly the Canon charger was able to charge the BM battery to 100% but it never gave the indication that it was finished charging. But back in the camera it said 100%. Of course then it seemed to drop charge very quickly with just a minute fiddling in the menus. The BM battery is probably on the way out anyways. Got a couple RAV LP-E6N's coming next week to bide me over till some more OEMs are in Stock at my dealer.
This camera burns batteries so I think I better add another to my outstanding order for just a single spare.
After shooting tomorrow I will try the Canon charger on the Canon battery again and see if it will get to 100 now.......Show more →
I have ended up with about 7 batteries. I use the mechanical shutter, and I am getting close to the Canon advertised 300 shots per charge. In other words, not good! However, all my batteries do charge to 100% (after I deplete them below 93%ish).

I’m genuinely curious under what circumstances you’re getting 300 shots per charge. I got over 1,000 taking pictures of dogs at the dog park for a friend of mine. When on a landscape trip I used a battery over 2 days and got over 600 shots.
I am playing around with settings a lot and chimping and I’m getting 700-800 shots and still have 30-40% charge left. That’s with the LP-E6NH batteries.
The upshot: the new LP-E6NH batteries don't give you much more capacity after initial wear (about 8 recharges). Benefit is all about communication with camera firmware in the new R5/R6.
with R5 I shoot mostly (95% or so) in ES mode and get about 1000-1200 shots per full charge from the Canon LP-E6NH.

I have 2 and they both charge to 100 percent. I am shooting ES and getting over 1000 shots per charge. Probably over 1200. I've been going out 3 to 4 hours at a time and one battery, if full, will cover it.

Given the trajectory of the graphs it seems like a more logical explanation is that the batteries have built in capacity limits to prevent long term degradation, as has been common practice for Lithium batteries for some time now.
Of course, it is also possible that the battery contains exactly the same cells as the LP-E6N, and they just unlocked a higher percentage of the usable battery... It is Canon after all.
... was done by first fully charging the batteries, and each and every time they reported 100 percent charge once put in the camera. It was the draining of that 100 percent full battery that allowed the determination of the actual charge.
That said, the actual charge shrank over time. The plateau after a bunch of cycles is about 1.93 mAh - which sits about 1/3rd the distance between the old LP-E6 ratings (1800 mAh) and the newest LP-E6NH ratings. This was measured by a device designed to fully charge the battery, and then drain it and charge it again to measure how much it was able to drain.
I think some people may have been confused in that they thought this reduction in charge meant that it showed up as not fully charged on the battery meter in the camera, or is related to that sort of issue that they've been having with their own batteries. Just wanted to clarify that the reduction over time has nothing to do with the percent full displayed.
Just to update...I updated this thread on October 3rd with all issues resolved. My batteries charge to 100% now no matter how I charge them (in camera, Canon charger, 3rd party charger). But it didn't right out of the box when I got the camera.
I have a 2nd Canon OEM battery which charged to 100% first time but I did that in camera which is how I got my 1st one to charge to 100% back in October.
