This try tabu was suggested by my Aunt mainly because she heard a fable about longer lasting batteries through freezing the batteries. This try out was done by using 2 batteries and by using a torch to drain the barrage fire life. The finished taste took approximately 9 weeks. Aim: The aim of this essay is to test out whether leaving AA batteries in a electric refrigerator or deep-freeze leave alone have a longer life drag than AA batteries that have been leftfield out in normal get along on temperature. It is also to scram out how cooling affects the chemical reactions inwardly a battery thus in turn, how it effects the higher status of battery life. Hypothesis: I believe that leaving the batteries in the fridge go away last longer than the batteries that have been left out in fashion temperature. Furthermore, the batteries that have been left in the deep-freeze will last even longer.
