The issue with these is the low battery warning. Once the voltage starts dropping you don’t have much time to notice. Not a problem for active devices, but things like door sensors may give you just a few days between 80% and dead.
Absolutely. Different battery manufacturers use different discharge profiles, some gradually lower voltage in a few steps, others may just die with almost no warning, so it might take a few tries before you find a brand that works for your device.
