Battery Calculator
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.
