Beans, Bullets, and Band aids have long been known as the 3 B’s of Prepping. I personally added Batteries to my preps as the 4th B. I have prepped with both alkaline AA and AAA cells and rechargeables, along with solar chargers using the Rule Of Threes. Re-furbing old alkaline and te-chargeable cells is a great idea that allows you to stretch your power preps and take advantage of those with less knowledge than you have who are discarding ‘dead’ cells. Pay attention, sheepdogs and preppers. This is good stuff.
