Alternatively, has anyone here successfully performed
surgery on a Dallas
module? I have disconnected the battery from a Mostek 48T02 from a SPARC
and soldered on an external Lithium cell, but the packaging makes it easy
to get access to the battery wires coming down from the top (I even put
the battery on a 9V battery snap so it's easier to replace) I haven't
heard of anyone doing this for the more sealed Dallas modules.
So... anybody else suffer though this?

Annoying surgery, not impossible. The battery's atop the IC, usually a
CR1220 or so type cell, soldered to a couple pins.
Not sure if I did this on a Dallas unit offhand, know I have done it on
epoxy-potted and on clip-on plastic cover type RTC's.
Myself, I put in a vertical battery holder and use CR2032's usually (Just
have to stock one battery, then.)
