Is a replacement battery available for 9120 I've used for a number of years?

GN Netcom probably would know. If you can identify the battery type, you can try obtaining a replacement from some other source.

I can not get my headset GN netcom 9120 to sink-up with the base

this has not synch up keep headset in cradle and remove power at mains plug or power lead from base count to 5 and replace power if no flashing is seen then you might have to repeat the same procedure a few times for synch to happen
the only other reason for no synch is battery in headset is not charged enough

Battery Light Won't Go Solid. Lot's of clicking sounds and lights flashing (GN Netcom 9120).

It sounds like it may be a defective unit in that the charging points on the base and the earpiece are making intermittant contact, hence the clicking noise you get when the unit goes into headset mode and the fact that the battery never reaches a fully charged status.

A couple of things to try:

  • Check the charging points/contacts on the base and the earpiece for damage.
  • If they look ok, gently clean them with some spirits and try again.

Cannot hear anything out of the earpiece of my GN netcom 9120 wireless headset

I was also experiencing the same problem (also after a power failure / storm) -- apparently good battery charge, connections ok, etc. I then tried removing the battery from the headset itself, waited 30 seconds, and then reinstalled the battery. This seems to have resolved the problem.

It is fairly easy to open the clamshell, but you will need a very fine Phillips screwdriver to remove the battery hold-in (it's really not a hold-down, it just keeps the battery in place. Reassemble the same way -- be sure to keep positive to positive and negative to negative.
