Is that the BIO IMR? Curious that it's worse than the standard Sanyo 2600.
These new panasonics do look good though.
Looks really good. Thanks for the detailed review Old! Frontpage'd and Sticky'd.
Original AW IMR , still performs about the same as when I got it ...
Did 3.1A in my MTE when I got it , still does 3.1A ... Same with the AW2600 ... Cant fault them for that ..
Thanks for the review! I'm glad you confirmed some of my results. I thought I needed a new multi-meter after testing some of my lights!
I just wanted to make this clear the new Callies Kustoms 2250 Battery is an IMR Battery. I had stated it was was a standard lithium battery. Some of the Panasonic sales literature was very vague.
Later press releases have confirmed it is in fact a "Nickel Manganese-based cathode"
It's just surprising that it's worse than the sanyo. I mean, what's the point if that's the case?
Another typical high quality "Old" review. Thanks for having such a great battery addiction and sharing your experiences of so many of those fun little cylinders. I hope I will live to see affordable carbon nanotube battery technology and 6000+ mAh IMR 18650's.
In our typical flashlight applications? Safety. That’s about it. IMRs are for higher discharge rates that regular LiCo cells are not rated for.
The Sanyo 2600 is an incredible cell and is still preferred by many people over the newer 2900/3100 Panasonics. They hold their voltage much higher than one of the high capacity Panasonics for 90% of their discharge. Now THESE Panasonics are much more like the Sanyo, only they have the added benefit of safety AND the ability to go beyond 2C.
Callie's High Discharge and other @ 3A (to 3v):
This post cleared about all questions I had with the performance differences and pro´s/cons with these batts. Thanks.
+1, Great job Old4570 !!!
I would like to live to see a zillion mAh "batacitor," as proposed by the late author Philip Jose Farmer.....part battery, part capacitor, it charges up almost instantly and can dish out power at a trickle, or all-at-once. 
Great review, very interesting!
Just like the 3100's some people assume the extra capacity comes at the price of safety. Please understand I do not consider ANY battery "safe"
So I made a quick little video to see what really happens when they are shorted out.
You sir, have big brass ones. LOL
But have you tried charging it back up and using it? :p
Now thats something Id like to see other battery suppliers try
"You sir, have big brass ones. LOL

"
LOL sorry I tried, the battery is Toast! its now reading .46v I tried 2 chargers. Both said connection break. I even tried the nimh setting to get it back up to chargeable condition. No luck but we can rest assured it lead a valiant life in the name of science 
It is precisely coz of this characteristic that i'd love to gun them in DD triple XM-Ls for the Sanyo 2600. At $5 a piece, can't go wrong. The XTAR 2600 have very aggressive PCB protection but i suppose the discharge curve is similar. I can't get Rev Jim's Panny stuff, so these will do nicely. :D
intresting thread but at $29.41 AUD each shipped to oz puts me out
I saw you post on CPF , and yeah , upsetting the status quo !
There will always be someone .... But whats important , is the results .. And getting the info out there ..
you dont mean me
if so its funny how some peole on cpf thing its ok the parrallel charger batteries when the cells are discharging and charging them selfs from 2 to 6 amps + when connecting in parrallel and they think they are all corect and it will not harm or increase the internal resistance of the batteries over time, they make out like people who series balance charge are crazy,
I have less respect for CPFs "experts" than ever. I'm still an idiot when it comes to the whole thing, but that reads like a total backtrack. "Well no lithium cell is entirely safe..." Yeah... you wouldn't hear that if the cell said AW on the side.
Where is the data that shows parallel charging increases resistance? I’ve never seen anyone ever say balanced series charging is crazy… just charging in series without balancing.
