Although this has already been mentioned in this thread. I hope you understand that there is no way ever that of the 100% you put into a battery pack you'll get that same 100% out.
Main source of loss is heat/resistance in the charging part. It takes a certain amount of energy to raise the temperature of your pack from roomtemperature (say 20 degrees) to the maximum temperature (say 50 degrees).
This energy is supplied by your charger and is counted as energy going into your pack. Most of it is stored chemically in the NiMH but the rest of it is used to heat up the pack.
When you discharge your pack the reverse happens. Although the BatMan keeps your pack cool so little is waisted on heating up the pack, still some energy is lost in the packs internal resistance.
All this explains the difference between the energy your charger supplied to the pack and what comes out with discharging.
Hope this helps...
