I did a little data tracking/research to figure out which batteries work the best and this is what I found:
Rayovac - about 8.5 days use.
Sonus - about 8.5 days.
iCellTech - I get about 9.5 days from these!
I only recorded for about two packages of each battery brand so definitely not conclusive and it was for my personal hearing aid (which I use about 15 hours a day). I would say that the ICellTech is definitely a good battery brand.
