Questions about this item

What voltage does the 9.6V Ni-MH pack deliver to the Okuma MB4000?

The pack supplies a nominal 9.6 volts to the CNC machine's memory-backup circuit.

Will the 70.36 x 67.88 x 34.52 mm case fit the MB4000 battery compartment?

Yes, those dimensions match the original housing so the pack seats without modification.

How do I install the replacement without losing machine parameters?

Keep the CNC powered on while swapping the pack; removing it with the control off erases stored data.
