Hunter's comment
JAW Batteries are unique. They are the only AA (1.5V) batteries in the world that is made with environment-friendly materials to store a charge. This charged material stays inert until it is triggered by water.
Jaw Batteries are designed for emergencies. They can stay inactive for 20+ years and can easily be activated by water.
In case of no water they can even be activated using mild, tea or even urine.
