I just thought I'd share this gem from a statement on how to dispose of a redundant RSA SecurID token (http://www.rsa.com/... (PDF))
Does anyone know where the lithium goes?RSA SecurID tokens are lead free, and use a low voltage 3.3 volt lithium battery. When new, a token has less than .5 grams of lithium. This amount decreases as the token is used. This amount is very small and does not pose any health risk.
