ok update.

You want the 5.0 AH cyclone replacement for this.

They are not acutely 6.0VDC, They are 6.7 to 6.6 VDC

and this (.6 - .7V) is critical to make the hard drive work properly!

* theres no way around it * trust me.

( if you are interested in running the HD from battery )

This battery I have chosen sits fully charged at 6.4volts.

It will run Spin/boot from that hard drive, but only for about 10 to 15 minutes (max)

(Once freshly disconnected from the charger) Then as soon as the battery goes below 6.4Volts (witch does not take long)

the HD will stop and not spin back up, even if you are already booted into the os.

If you are booting the os with out a HD or are maybe using Single or Dual Floppy drives or external(tested), It will run for hours and hours no problem, on this alliterative (non cyclone) solution.
