Skeptical at first but they're surprisingly good
One of my smoke alarms chirped. These arrived and I charged them via USB. I was skeptical given that typically USB charging batteries potentially represent an issue but realistically these should have low dischargeIn addition, it having a USB socket, doesn't affect the size which means that it still fits in my smoke alarmAlso realistically, disposable 9V batteries are better value for money, but the biggy here is that it has significantly less waste and if I ever move to a wired setup, I could just give them away to someone.

3 out of 4 work
1st one dead (0.02V at terminal), 2nd one 9V at terminal and now in the kitchen scales, 3rd and 4th seem to be 9V too.Can't be bothered to send them back as I need the kitchen scales.I took the dud one apart and found the LiPo battery was at 2.67V - too low to charge.
