I agree; even internal fixed batteries should be marked. The markings
are for service technicians and recycling people, not just users.
But 60065 and 60950-1 are nearly dead. You should look at 62368-1.

It looks like a move to regulate Amazon and similar sources. At present,
in the UK at least, there is little surveillance of goods ordered in
small quantities by members of the public, with the exception of

of computers, but I have one which is half-dead because the manufacturer
refuses to update a driver that Windows 10 now needs.

I don't know. Maybe the UK has an MRA with the US, independent of any
EU-US MRA.

I fully agree on the Ken's concern. How can the manufactures change
compliance. In other words, that person must have access to all the
manufacturing data for the product.
