9 Volt Battery Storage

[Peter Laidler]

The commentator said that it only works with 9v batteries. Surely it'll work with lesser batteries too as we were taught this as a method of firelighting during our basic survival training and later as a sabotage method during advanced military training

True, but the 9Volt battery is the only one in common usage that has both terminals on the same end, making it much more likely to accidently short-circuit.I've used this as an emergency fire starting method for years and keep one in my kit when ever off-highway traveling.
