So I have a tuya smart key finder that using Bluetooth technologies, and they claim it can last up 6 month 1 battery, but when I use it, only lasted 1.5 months and it self shutdown.
I'm fed up changing 2032 cells, now I got a thinking.. Can I instead keep using 2032,i wired this device to a single lithium battery (18650 or 14500).
But I'm afraid damaging the circuit, I heard 2032 is 3.2V max, meanwhile li ion has max voltage 4.2V.
Probably second alternatives is putting 3 AAA rechargeable energizer battery it would result 3.6V... What u guys think? I don't mind it getting a bit bigger-atleast it lasting a lot longer.
Here is the device pics :
