I'm interested to know the current drawn by a kitchen LCD digital
timer. 

(1) How much current does the timer draw when counting time?

(2) How much current is drawn when the piezo buzzer is sounding? 
(Averaging out beeps and silent bits.)

My guesses are 2mA and 25mA, respectively. Is that about right? 


I mean a timer similar to this one, running off a 1.5V battery.
