Panasonic CGR17670, CRG18650C, Sony US17670

Only a few people ever seen “Bigfoot”. “Littlefeet” is not that shy. The Sony Energytec 17670, measured 2.2 volts after not being use for many years. The Panasonic 17670 came in kicking with 3.9 volts. These batteries was a rare find for me but no matter what the size or how old I put them to work immediately.

Hello, what capacity did the 17670 panasonic give you?
I have come across quite a few packages that contain these cells and I don't know if I should put them to work with my 18650s.
what is your experience with them?

Oh, but they're too long! You'd have to cut the bottom off to use them in a pack

Hello Powerookie, I did not test the cells and I did not put them to work in my pack. My pack is 14s and I have 13 17670's. Adding a 18650 looked goofy to me. I'm sure to come across more, when I can make at least a 14S2P then I'll play with the those baby cells.
