I agree, the point I'm trying to make is. If you "have to" store you batteries in the fridge to keep them form over heating, there most likely something else going on. You may have a problem and not realize it. If it were me having the problem, I would want to fix it. And I would want someone to tell me I had a problem and help me fix it. But some just want to stick their head in the sand, or batteries in the fridge and ignore the problem.
Firstly the storage of the batteries in the refrigerator is a battery cell temperature management method only. As for something else likely going on yes there is in my case I live in a location where the climate is far different and hotter than most of those who are bleating that it is a waste of time. Mind you those same persons will not evaluate the claim or do any proper research themselves.
Yet another case of if "it doesn't effect me then it is not a problem", combined with the true head in the sand attitude mentioned by some here. Not only did I investigate the heating and puffing issues I was having with batteries from a number of different manufacturers, (mind you prior to any refrigerator usage), I also investigated the rise in temperature and internal resistance values of the individual cells in the battery packs overtime as well as self discharge properties at various temperatures.
There is a somewhat unhelpful attitude in some that they do things perfectly and that anyone who does different is wrong, has a problem, or is possibly even mentally defective. Such an attitude never adds anything positive to a discussion and at times can be destructive in itself. If something is proposed or mentioned that you do not like, understand, or believe is applicable to your situation, does that mean it has no application for any other user in the entire world?
This forum has a worldwide reach. This post was aimed at those who live in different climates and have far far lower incomes than some others. If the refrigerator is not for you, then lucky you, but to dismiss and attempt to belittle something you refuse to evaluate or obviously do not understand is a sad reflection upon your personal attitude and the forum.
Try it if you are having issues and if it works for you then good and if it doesn't that is good also but at least try something before you dismiss it outright.
Have fun!
