This afternoon, when I was doing a bolus, after checking my BG, I wanted to enter the bolus but my pump screen was blank. I quickly changed the battery and everything came back up normal. (My BG was 7.7 when I checked and the pump hadn't lost any settings, so I assume I caught it very quickly). However, there was no low battery alarm. I'm sure when I looked last time, there were still at least 2 bars in the battery icon.
I looked through the alarm history, and the last time I had a low battery alarm was August 14 - I know I changed the battery then.
Has this happened to anyone else - pump battery dying with no warning? Should I call Minimed?
