Battery run competition, category 41

The boards I was using had very low specification for quiescent current in the ~x0uA range. But a freshly charged LiPO with the 41C(CV/CX) in standby only lasted about 3 days. What kind of life are you getting with a 41C in standby versus operating?

Specifically I used a:
1. SparkFun Power Cell - LiPo Charger/Booster (~50uA)
2. Adafruit Mini Lipo w/Mini-B USB Jack (~25uA)
3. Converter salvaged from a Battery stick
All of these should have been several orders of magnitude less then what I actually saw which was batteries dead at low voltage cutoff after about 3 days. I used several different batteries and calculators to test. If I leave the batteries out of a calculator that last as long as I have been testing them (about half a year with only minor voltage drop from full charge).

I am a Chem Eng, not a EE, so this is frustrating to me and I do not know that I am doing something wrong.
