Most people overlook this one. The simple fact is that excess heat is not good for your battery and will significantly shorten its lifespan. See the table below (source Battery University) - a hot battery will degrade in health much quicker than a cool one.

Summary: We highly recommend, for example that you not leave your electronic cigarette on your car dashboard or lying out in the sun at the cottage on the lake this summer. We also highly discourage baking your battery in an oven.
