A chemical symbol printed under a crossed-out bin.
Also known as: Battery metal symbol, Pb marking on a battery, Cd Hg Pb battery mark, Letters under a crossed bin
Pb, Cd or Hg printed under the crossed-out bin on a battery means it contains lead, cadmium or mercury above a threshold. The letters are the whole of the additional information — the bin already says separate collection, and the symbol says why it particularly matters.
Indicates that a battery contains lead, cadmium or mercury above the threshold set by the batteries directive, using the element's chemical symbol.
Contexts: Packaging
Supplements rather than replaces the crossed-out bin, adding the reason separate disposal is particularly important for that battery.
Contexts: Packaging
Uses thresholds set by regulation — different for each metal — so the absence of a letter is a statement that the content is below the threshold rather than that it is zero.
Contexts: Packaging
One or two letters of a chemical element symbol printed immediately beneath a crossed-out wheeled bin device on a battery or its packaging.
