I am working on a project in which I have to run a ESP8266 module for months together on a coin cell. Most of the time the ESP will be in sleep when received an interrupt it should wake up connect to internet and send a mail then go back to sleep. It will receive only about 5-8 interrupts a day.
I have decided on the CR2032 cell from Panasonic so far. Datasheet link given below
Am I in the right direction> Please guide me if I am wrong and provide me an alternative
