Heat threat

We may always feel that when we use the laptop in a long time, the temperature of the laptop will increase in a short time. However when the laptop has been used in the environment like this for a long time, the life of the laptop will be shorten, so is the laptop battery.

Almost any electronic device like your replacement battery that is built to be carried around may be damaged by temperatures above 100 degrees or so.

Also, if you're a digital camera user, you need to be aware that the camera may have limits on temperature tolerance, especially if you are using a digital still camera for shooting video. The imaging chip in many cameras was designed primarily for still use with the ability to do video in limited situations, that also including your laptop battery.

Snapping still photos causes much less heat to build up in the imaging chip than the constant use of doing video. Check your camera's manual for any cautions about using your camera for doing video for more than a few minutes, especially if using your camera when the body of it is exposed to direct sun conditions.
