Just had a strange experience with these cells.

One of my cellbanks 112p was indicated low by my Batrium, so I swapped in another cellbank.

ICharger reported 182 Ah cap, (should be 250)???

Desoldered all fuses on the positive side and found that 24 of these cells were zero volts which were the number mounted. ?? Seems that they had committed collective suicide.
What I, so far have checked of the Remaining 88 cells of various makes and models, seems to be OK.

Think I will have to inspect my other cell banks to see if any more of these cells are mounted and if they are OK.

It would be interesting to find out what the IR of these cells is or was.
My findings on any CGR******* Panasonic cells is anything >65mΩ  (AC Impedance, 1000 Hz 4 wire kelvin as per manufacturer) is suspect to SD and degradation.

If 18 X 650 = 2200+mAh then we have power! 
May all your Cells have an IR of 75mΩ or less Smile

I had 2 of these cells trip CID in storage. Sounds like all your cells tripped CID during use.

If You accidentally charge these cells in sub-zero temps, this is what they do. Last spring I had 42 cells that just stopped working.
