Confusion between Peukert Effect and charging efficiency? The Trimetric instruction manual has some good notes on all that. Worth a read.
Also the Magnum manual has something about the specs being at 25F it goes off the specs other than that, and he was having all sorts of over-temperature problems causing it to do its charging pull-back trick.
I don't trust all this kill-a-watt method instead of just reading the amps without really knowing what the conversion factor is. Needs a calibration cross-check. But to do the cross-check you need an ammeter, so just use that in the first place :)
