@JahFyahh - I still haven't managed to et round to it. I've been really busy since this project and its still hectic here. I'm sure i read a few reviews somewhere, here or google. Not sure.
@ceech
I really like this design, however I think it has a problem:
According to the datasheet the TPS610986DSET has no feature to disconnect the load at low battery voltages. I think the result will be that e.g. a ESP32 or other power hungry chips will not power up properly. The TPS63031 might therefore be a better fit.
btw.: Do you still sell assembled versions of this design? Would you be willing to create a new version with the TPS63031 and probably also with 10 or 20F capacitors or an board to solder your own capacitors.
Best regards

In deep Sleep the cunsumption is below 19µA, but i have to send with PA_MAX. On some Windows the open/close frequency is verry high, so the battery is to fast emty.
The CR2032 is good, but i want more "lifetime"
Hi @Siddharth-Velappan
The warmup time of the MH Z19b is 3 minutes. So 2 is probably fine, but you could probably do 3 just in case. Although 2 would save your more battery time.
Do you mind explaining your setup a bit more? I would love to do something similar but I do not know where to get started with the PIC microcontroller!
