About Photovoltaic Energy Storage$begingroup$ I had this happen with three alkaline LR6-AA batteries in series, only it happened to TWO of the three. The device ran with new batteries for over a year. It last reported a battery level of about 30%, and then it just died. When I removed the batteries, one had +1.6v (way more than I expected) and the other two read -0.44 and -0.34.
