Hi Egge,

I've repaired both types without drama.
If the NVRAM is separate to the battery, check the leakage current and if necessary replace the NVRAM too.
It's easier to de-solder than a DS1245Y-120 anyway.

Before buying a unit make sure that SPC passes.
The trigger chips in these units run very hot and can fail after 10-15 years.
They are almost impossible to find.
