About nominal capacity and true capacity, currently I do run some tests.
Before a year ago, I got some no name AAA 900mAh.
I have one small LED desk lamp, that needs 40mA to operate.
The fake 900mAh did not last more than four hours = 400mAh
Currently I do the same test with the Ansmann AAA 1100, I have also one digital timer with alarm,
and notifies me every 60 minutes, currently are running for a second hour.
Soon I will have some true proofs about " Real capacity "
