I've collected a few of them and they are robust and rechargable batteries. A common battery is
IP17350 1100mAh 4.07Wh
(Date of manufacture the one I see on the one I'm holding is 20210613).
Anyone got any idea to use them besides small flashlights? They also have a pressure sensor on the LED and a nice metal case pretty often.
- dgacmu 3y agoDepending on the battery there are cheap AliExpress boards - or diy - to make tiny UPSes for a raspberry pi or other usb-powered device. I don't know for that specific battery; I have some that take 18650s, though. One 18650 can get you several hours of runtime for a pi zero. The battery can cost more than the zero. The cheaper one cell UPS boards are about $2 (plus shipping). An advantage of single cell UPSes is that you don't have to worry about balancing, which is a bit of a pain with scavenged cells.
