Perfect linearity, reliable low voltage cutoff and achieves claimed mah rating.
on November 9, 2013
The linearity of these cells is amazing. I purchased four of them and put them through the drain test using a CBAIII battery analyzer. All four cells show a decay curve during a 1 amp draw with each line stacked on top of each other from 4.00 volts through the point where they cross the 3.00v line after delivering a very respectable 3270mah, after which they go off a cliff. At the acutal 70ma which I will use them for in my projects, I'm sure they will deliver over their rated 3400mah. My testing showed that all four cells reliably cut off sharp at 2.40 volts. That's handy to keep me from damaging them in my unattended project boxes.
If I can get 3270 out of them with perfect voltage linearity in independent single cell testing at a 1 amp draw down, I'm more than satisfied.
