Battery systems. Okay, folks. Let's say that you, me and a gazillion others are aptly prepared for a SHTF scenario. Governments collapse, people start killing each other for what they have, many go into their bunkers to wait this out. Whatever happens, happens. WHAT happens, really doesn't matter, as long as it results in no more businesses operating as we knew in the past. No more supplies. No more grocery stores. No more solar, wind and hydro companies. But, also, no more battery manufacturers. Even China got caught up in this, my SHTF scenario. Good panels will last 20 to 25 years, maybe longer. Even cases of new, unopened solar panels, I suppose, wouldn't hurt to have extra panels stored. I have no idea how long wind turbines will last. That isn't my forte - and not enough wind in Cambodia to concern myself with owning one. However, a proper prepper is prepared (I just had to say that) and will have spare parts for his wind and / or hydro generators. Controllers will probably last 10, 15 years? Even so, you could work out how to fix that, or build a new controller, even if only a simple one to allow regular charging of your batteries. Keeping a new one boxed away somewhere, probably wouldn't be such a bad idea either. But, the one thing you can't just keep on a shelf, can't keep boxed up waiting to be used and unused indefinitely, is batteries. Once your battery system dies - it dies. Even if your FLA batteries will list oh, 10 years, eventually, they WILL have to be replaced. Remember now, we are in a SHTF scenario where NO one can get these items. So, what then? Do we plan ahead (like, today?) and buy some Edison NiFe batteries? (I have heard some of Thomas Edison's very own batteries have lasted over 100 years.) For me, that would seem to be the only logical conclusion to this. I mean, even with all this new technology. I don't believe ANY manufacturer has come up with batteries that will last a century. (Please do feel free to correct me if I am wrong here.) What got me to this point was, over the past month or so, I have begun looking at new batteries to buy. But, since I am on some alternative energy forums, some prepper forums, some off-grid living / homesteading forums, etc., it finally hit me to throw this question out there. (This is the only forum I will start this thread on, by the way.) So, after my poll even, asking what type of batteries others would go with, none of us took that into consideration. What if... I mean, if we don't have batteries for our energy systems, we might as well not have the systems at all. There is no way to store any energy generated, without the batteries present. So, again, what do we do in this case, folks? Ideas? Input? Discussion, please?
