Recently, we heard many battery recalls – plug-in vehicles, mobile phones, 787 dreamliners – battery safety concerns appear to be ubiquitous.
Take a moment to consider how you handle your devices (phones, computers, power tools, etc.) to reduce risk of a battery incident: e.g. Do you charge your cell phone overnight? Do you sleep with your cell phone next to you, or under your pillow? Do you charge your laptop while it’s in your lap?

PBS has recently broadcast a very interesting show on battery technology and safety – (this is rather long, but entertaining and informative) - http://www.pbs.org/video/2365946487/
