Whenever I create smal IoT stuff I always try to see how I can improve the battery life, there are a lot of factors to consider when choosing battery type but also hardware that is suited for longer battery life.
check out my Temperature sensor to see a good example on how to change a few components can change the battery life exponentially.
Different types of batteries have different charges and depending on chemicals will act differently in warmer and colder climates.
19000 (Lithium-Primary) 3.6V
|9V Transistor||565 (alkaline)
|6V Lantern||26000 (alkaline)|
|CR2032||240 (Lithium-Primary) 3.6V|
|CR2016||90 (Lithium-Primary) 3.6V|
|1/10 D||1000 (Lithium-Primary) 3.6V|
|4 Farad Cap||1 (loses 1 volt in 1 hour at 1mA)|
