How long will the batteries last when using the DA-2006P?

The DA-2006P will run a 60 BPM ECG waveform continuously into a monitor while on battery power only for approximately 6 hours without the back-light on.

The “Battery Life ” indicator read 17% after 6 hours with the back-light off and 9% with the back-light on. It would still read a Defibrillator pulse and a pacer pulse with the back-light off. When a button was pressed the back-light would come on and the “Low Battery” indicator would come on until the back-light went off.
