Cool. Kinda like a 'heat fuse'. I suppose this 'separator' would perform it's function due to any temperature rise, like for example a battery being stored and covered with a blanket or jacket while it's in a closed windowed car that's regularly in direct sunlight, or something like that?
That's pretty much the primary reason I love this forum and it's members. I have learned
bunches just by reading thru other threads and particular posts, and the few times that I asked a question, I got educated.
