Lithium batteries have a dark side.
If the internal lithium is exposed to water a flash fire occurs.
Watch this video of lithium batteries VS. water and see the danger that is carried in your pocket.
Many of us carry cell phones with lithium batteries inside. We also carry GPS units, flashlights, you name it, with lithium batteries inside. Well there is something you really need to know about those longer life batteries.
Water and lithium do not play well with each other. A sealed lithium battery if broken open and exposed to water will cause a flash fire. The heat is intense and the damage could be dramatic.
Many thanks to The King of Random on Facebook. In a survival situation where fire is needed this not so safe method might be useful. It is also good to know the dangers lithium batteries pose if broken open exposed to water.
