I'm on my first day with these, and so far, so good. I just switched out the battery after about 10.5 hours and 3 ml of juice, and it read 3.72.
In what charger you are charging CGR 18650 Panasonics?

I am asking because in post #17 charger terminates charge too early (4.10V).
How about Pila? What voltage your CGRs are after charging in Pila charger?
You are absolutely right Decidion,
Do not forget that one of the best ways (if you want to extend life of your batteries) is to charge them to 80%-90% .
Lower cut off (on IMR there is nothing to cut it off, so everybody should be very careful) voltage should always be above 2.8V (new panasonic batt can go to 2.5V), and that is the main reasons for manufacturers to start modifing bare cells by adding el. protection circuits .
What exactly is a "spring compression pic"? If the question is about the length of the cells, then the answer is: They are just as long as the AW IMR 18650. The Panasonic CGR18650CH are unprotected safe chemistry, there is no PCB glued on and no additional shrink-wrap foil to cover the additional wire, so they are not thicker than standard.
The "1865" part of the model number describes the diameter and length of the cell in millimeters. They fit into the REO Grand just like an AW IMR. The only difference I can see is the size and shape of the positive terminal - the AW IMR terminal is a hair taller (maybe a fifth of a millimeter) and smaller in diameter.
So do you mean to ONLY charge them as far as 80--90% of full charge?
Yes, that is correct.
Battery life span will go up, but energy density will go down. Meaning , you will have to charge your battery more often.
Maybe, not the best option for PV users.
Trade off...
Giving up valuable minutes of vaping in return for longer battery life.
Ok, they charged up to 4.10 - 4.12 volts and I am vaping away right now. My understanding is that new batteries take a good 15 or so charges to get up to full speed, so I assume they will go up to 4.18-4.20 like my AW IMRs in a week or two, time will tell.
One thing I have noticed is that the overall length is identical to the AW IRMs, however the case on these panasonic batteries is 1mm longer and the positive nipple does not protrude as far as with the AW IMRs. In fact, the nipple on the Panasonic batteries is flush with the top of the case. This means the spring is in fact compressed 1mm more and that you have to depress the button 1mm more to get it to fire. This really isn't a big deal to me, as I feel there is still plenty of room for a spring collapse failure and I have a 3ml syringe cap on my button for comfort anyway.
I'll report back in a few days to give some idea on how long they last compared to the AW IMRs, but it won't be scientific. At 1600ma, the AW IMRs last me 1-1/2 days, so I am hoping these 2250ma Panasonics last 2+ days for me. Again, I expect them to start to perform better after 15 charge cycles.

I full well understand what the battery numbers mean but not all 18650 batts are the same measurements as may would assume. So yes I was curious how they relate size wise to aw imr batts for gauging the amount they may compress the springs.
