I wouldn't worry too much about the exact reading; these things move around all of the time. For example, I just pressed mine 5 times, and got ranges from 41-45%. This is normal.

This morning, when I first started reading, the report was 89%. A little later, it said 92%. Still later, it was 94%. I am still using the batteries that came with the unit. Is this typical BP battery behavior? Which reading is likely to be the most accurate? Crystal
