IMR Panasonic 18650 Li-Mn-Li-ion CGR18650CH High Drain 10A Rechargeable Battery Cell

I saw some stress test comparing aw´s and these panasonics and saw that these are what I´m going to buy from now on.

Link to stress tests please!

2,250 miliAH is what the graph on that link shows.

for $10?

Looks like a pretty good deal if I got that right

Edit...I just ordered 3 of these, so we'll see how well they work out in my Grand.

I've been wanting to grab these for some time. Tell us what you think Decidion, as I was just about to pull the trigger on some Protected Tenergy batteries cause they were about 7 a piece.

 

[bushmaster]

I'll be interested too. My AW's are getting old.

 

[Creniker]

Gonna go ahead and get these. As far as I can tell this is a IMR with more capacity and safer. And cheaper. Can't really go wrong.

I ordered a couple yesterday, anxious to see how they perform.

 

[stravaigin]

Please come back and tell us what you think of them

 

[Decidion]

Doh...they came in to the post office today, but it's closed so I can;t get them until Monday ;\

I just purchased 2, had a bit of trouble with the website... but they are on the way right now!

$8.76 Panasonic CGR18650CH 2250mAh Li-ion Battery [Panasonic CGR18650CH] - $8.76 : Led Flashlight-International Outdoor Store

Ok, got them in and they are on the charger, since they arrived at 3.60v

I did notice that Orbtronic raised the price by $1.08 to 10.99 now though...

 

[muriarte]

Good thing I bought mine before the price change!

 

[Decidion]

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.

Looking forward to your further review, Decidion.

The Panasonics with the ...CH at the end (stay away from the ...CG) are indeed good safe chemistry batteries, suitable for vaping. We are currently testing a range of IMR and NMC cells in the German community: You can find the testing here: RE: SabbelMR's IMR Akku-Probierrunde - 42 .

The important thing is that there ARE indeed alternatives to the AW brand, especially in the 18650 size: Panasonic CGR18650CH, BAK B18650CC, Sony US18650V3.

When reading the diagram (The second one titled "Messungen auf Hyperion..." is our result diagram) please refer to the violet part of the bars. That's the capacity at 5 Ampere result.

You might not be aware of the NMC chemistry - that is a hybrid of the classic IMR and the classic ICR, basically a safe chemistry with higher capacity. Look here: Types of Lithium-ion Batteries

We are not yet finished with the testing, and a final result is not yet known, but we already identifed usable cells, some are even better than the AWs in our frame of usage.

We are waiting for a new sample for the BDLs - they have had too high variance in results.

18650:
Panasonic CGR18650CH
BAK B18650CC
AW IMR18650-1600 (For mechanical PVs not worse than the -2000)
AW IMR18650-2000 (For regulated PVs a hair better than the -1600)
Sony US18650V3 (Very new cell, might not be available yet)

18490/18500:
AW IMR18490-1100
BDL IMR18500-1100


18350:
BDL IMR18350-800
AW IMR18350-700

16340:
AW IMR16340-550

14500:
AW IMR14500-600

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.
