While it's true that a dumped car battery would at least raise interest or even suspicion, a buried one is significantly harder to stumble upon, however suspicion is still optional. Who is going to open a potentially highly acidic/hazardous car battery anyway? Something "rattled" inside, which suggested it was dry, and what ever rattles inside a car battery, everything is supposed to be fixed there, right? Besides, an ancient Varta battery - put that in a museum! There - the cover's blown.

Back in the days no one cared about dumped car parts. But nowadays just about anything raises instant suspicion if anything out of the ordinary lies about on the ground.
