    Welcome @SandersF, to the community!

    The device in question was a battery-buffered SRAM with a voltage of 5V, which has been obsoleted and uncommon for decades. I'm afraid you won't be able to find a replacement anywhere, and only a manually manufactured drop-in will help.

    Sorry not being able to help you in this case.

    Regards

    As said by @Peter BENSCH there is no replacement for that device but look at these links if you have a battery issue:

    May be you need to try that workaround.

    Look at the images here.
