Just curious - battery noob here. I had one battery fail on me, and when I tried shaking it around I could hear the liquid inside swishing around like I was shaking a bottle of water. It's a non-rechargeable D-sized LiSOCl2 cell for reference.
Could anyone explain to me what happened here? I understand primary lithium cells have electrolyte fluid inside them, but what could be the reason something like this happens? Is it a manufacturing error? Is it totally harmless? I have dozens of similar batteries and none of them have this issue.
