Self discharge, protected vs non-protected cells

[kreisler]

ive been measuring self-discharge rate of unprotected 10440's:

10440's

old4570 did a series of discharge tests of 10440's, check it out. the AW 10440's are rated 320mAh (which seems like a honest number) Also learn that the actual nominal capacity is 350mAh and not the (over-)rated 500mAh: [image] [image] [image] As a general rule of thumb, the max. continuous discharge current is 2C, which is -700mA (= -0.7A); please read it here: which links to: Protected Blue Ultrafire 10440's did exist at some point in time: http://dx.com/ultrafire-protected-…

i make heavy use of my protected 10440 cells (Tank E09, iTP A3) and i would use my unprotected 10440 cells only on special occasions (e.g. the iTP A3 requires 2 washers. two loose washers cause flickering and mode-switching). if need my unprotected 10440's (e.g. for the iTP A3 without washers), then i will interrupt and stop the above self-discharge rate measurement. i dont think that i will get to 6 or 12 months straight. i hope so, but i dont think so.
