How to recycle an expired EPIRB battery into a Flashlight

Boats and planes carry one or several Emergency Position Indicating Radio Beacon, EPIRB, for safety purposes. Batteries should be replaced every 5 years for safety. But all these discarded batteries are still quite charged after 5 year of shelf life, not being used. Why toss these without using them first? I built a simple flashlight that happemned to last 5 years ... until I had to replace my EPIRB battery again. This design is easy to build as well as very inexpensive. One of the failures to most flashlights is internal loss of conductivity within metal conductors used bweteen light bulb, switch and battery. It results in low battery voltage getting to the light bulb, even tho the batteries are full and thus the flashlight goes right in the trash. Use good quality wire to connect the elements of this flashlight. Simple and inexpensive switches and LED lights can be substituted in this DIY project. Make sure that battery voltage (12v in my example) match the rated voltage of your LED light. A more powerfull LED will result in shorter battery life and vice-versa. These long life EPIRB batteries are NOT rechargeable so it is a one time use ... perhaps 5 years like my last flashlight J
