Is that a trick question?
I have no idea...this is the first NeXT I've seen in over thirty years!
And I think this is the same machine I saw in Vancouver all those years
in my friend's basement...

At that age it might well be. So what? I think
they are still
available. Or you can replace it by a non-rechargeable battery.
That's what I did with the ToD clock battery in my Pro; a lithium
coin cell with a series diode to prevent "charging" is not an
ideal solution but adequate, and it would be better if I used a
Schottky diode rather than a plain Si rectifier diode I happened
to have lying around.

Battery leakage was the issue - having dealt with a great many logic
boards damaged or destroyed by leaking Ni-Cad batteries.
I've since seen a photo of the inside of the NeXT and it looks
like they
used a plug in Lithium battery, so that risk is no longer of much
concern to me.
