Re: Key Chain Blu-ray... With FlexDrive!
This battery was from DX, but I have tested these before and already knew the capacity was really just over 300mAH, and was real happy to see that the specs for the AW batteries match my tests! Actually most of DX's Li-Ions have ridiculous ratings stamped on them except for the 18650's. Hopefully the Power test will be done tonight - it takes longer to plot the graph than do the test :
What really is a concern, is the cell's internal resistance, which increases dramatically during discharge. It also increases considerably as the battery ages, which means the lifespan in a severe application like this may be a lot less than the expected 5 years typical usage. :-?

Is your 10440 from AW? Cos DX are rated for 600mAh, which is impossible, but your plot says "capacity 320mAh"...
Looking forward to the constant power discharge curve! I already feel bad for the battery..
