Each time I charge my lithium battery, I compare the number of watt-hours that the TSDZ2 w/OSF reported used before charging with the number of WH the Grin Satiator says were put back into the battery to get it back up to 80%.
Sometimes the numbers are not even close, as in 49/97, 44/69, and 12/103 (TDSZ2/Grin) for my last 3 discharge/charge cycles.
My money is on Grin but, not knowing squat about electricity, I have to wonder if maybe used WH is somehow an inherantly imprecise figure.
