What kind of battery does my timer use?

The majority of our times use AAA battery(s) - if your timer is older and uses a button type battery, it is a G-13 button cell battery.

Can I set my timer without having it beep every time I push the button?

The beeping will occur every time the button is pushed. To advance time without beeps, hold button down until desired time is reached. Loudness of timer is preset and cannot be changed.
