For the battery, I Dremeled (badly) the original battery box open and replaced the 3 cells with one of the recommended Panasonic lead-acid cells (https://www.amazon.com/gp/product/B005FNTY7C/).
It worked fine until it sat for a couple of weeks (unplugged) while I waited for the SCSI2SD stuff to show up then wouldn't power up at all. So, I took the whole battery assembly apart, measured 6v on the battery terminals, re-packed it still no love. Then I used the tried-and-true tongue test on the 9v and it seemed a bit weak so I swapped that out - Shazam! Now it boots up fine. The LED on the SCS2SD card blinks and the Mac shows a sad face, which is to be expected - no OS installed.
Now the bummer part; The pristine set of System 7 disks I picked up wont launch the OS because the poor thing doesn't have enough RAM. Looks like I'll have to find System 6 disks and/or a RAM card. Are there SD card images floating around with the base OS installed already?
