I replaced them in April. Should have had another 6 months or more but instead the charge is now at 1%... previous batteries lasted almost 18 months.
No particularly interesting history. Automations locked or unlocked it about 6 times over that 2 day period.
Not a question, just a frustration.
just be careful what you use them with
Some brands have unusual voltage graphs over the battery life, which can confuse devices that rely on the alkaline/NiMH voltage drop to detect if they are low on power
Some of the lithium ones set their voltage to a fixed value and abruptly die when they run out. This is especially problematic for devices like smoke detectors, as they can't notify you if they are running low
