Warning: Exploding Batteries
batlike writes "It seems I have been quite lucky up to this point as I habitually leave my laptop in the trunk of my car - which is just over the gas tank (duh!) . See this article in InfoWorld by Ephraim Schwartz for details. You may want to give it a once over if you currently use lithium-ion batteries."
Ok. Those batteries you have there are unsafe. They could catch on fire or even explode!
Fear not, I have the solution.
Buy my safe batteries, free of pesky thermal runaway, free of fire, and annoying explosions.
