Just finished the battery longevity test as outlined below, but
recording in mp3 128kbps format:
Total recording time was 19h 52m 48s in one mp3 file 1.06gb in size.
The external battery pack(5000mAh) lasted about 16.5 hours with the
internal battery (925mAh) taking over for another 3.5 hours.

PS That length mp3 file seems to be quite a mouthful for Audacity.
