Well congratulations on getting the low battery alert. I didn’t think that was ever likely to work properly, based on reports and my own experience. As for battery longevity, how long are you viewing the camera for (live view), or having videos recorded, per day, on average. I have just replaced the batteries in one of my cameras, in a high traffic area, comfortably using 4 times the activity for full battery life (as described by Blink in their support documentation), and I got six months out of them, so it checked out for me. Others, in less active areas, are still going strong.
