I’ve been looking for a definitive answer to the question of how to safely dispose of a Lithium Polymer battery (a “LiPo” as we call them) that’s no longer suitable for use. The “salt bath” method favored by some seems to have some problems, and according to this video, is actually not effective. The method described in this video utilizes a device called at Computerized Battery Analyzer. The actual one referenced in the video is discontinued, but its successor is available here: http://www.westmountainradio.com/product_info.php?products_id=cba4 I’ve seen descriptions of similar methods, but they involve something like a light bulb, which doesn’t seem as precise when it comes to regulating the current and properly draining all the potential from the battery. Of note: I found a couple of these CBAs for sale on eBay for significantly less than they cost new. I bought one, and I will report back once I get it. I have a couple of LiPos that have issues (usually a cell that’s gone bad) and I’d prefer to dispose of them rather than keep them around for other purposes.
