    no acceptable reason they couldn't just install a pigtail connector to a battery casing for easy replacement.

    That is exactly how the Brother EDM batteries are connected, 2 wires to a battery case mounted into the cabinet door.

    As far as Fanuc goes ...
    In the year of 2007 not having a battery management and monitoring circuit in the servo control is equally incredulous.
    Specially when the f'in battery doesn't just maintain a puny CMOS ram chip, but also powers some form of location detection device 24/7/365 !
    Haas dual battery solution plugs the pigtail into a socket on the motherboard and you snip out the old battery

    Depends on how much memory is being backed up by battery, and if this memory is used realtime, as in read from and written to many times a second as program memory would be, not just parameter memory. non volatile memory does have disadvantages as in limited number of write cycles and its slower too. You cannot assume non volatile is the solution. Batteries are inexpensive and the Haas dual battery solution is cheap and easy to install by even incompetent people.

    I'm not suggesting non-volatile to replace ram completely, but to store the "fixed" parameters there, load them in ram on boot, how many times is there a need to make changes to those stored parameters during life cycle of the machine compared to at least few thousand r/w cycles of even the cheapest flash chip

    that flash chip would cost less than the first set of batteries placed there at the factory... and basically zero grief for users later on

    When I replied to your first post, you were suggesting to put macros and programs in NVR but this would exceed the NVRs capability/useage. Other parameters such as tool offsets would also need to go in main Memory, along with macros and programs and this needs to be backed up with battery. So the only parameters remaining would be optional features I suppose that could go in NVR, but maybe for security reasons designers would feel that chip could be compromised, so why not just hide the features somewhere in ram since its already being backed up with battery.

    I think a law suit is silly, but I think $400 to give a number to keep you running is obscene. I don't like companies that do things like that, bend you over as soon as they get the chance, it leaves a very negative impression. If it was my business I'd give you the number, costs me nothing, but keeps you happy and builds goodwill so you call us when you need the next machine. We do that all time, give a little bit of free telephone support. I would not squander the goodwill with a customer for a measly $400.
