"Even the non-chargeable CR2032 will burn/explode if heated via self discharge in a confined space due to short circuit of a stack."

A solar powered garden light failed. On inspection there was a neat circular hole in the plastic container as the NiMh 300mah button cell burned its way through and disintegrated. Presumably an internal short circuit inside the battery - a replacement battery worked ok.
