Invisible Fence Dog Collar Batteries

Where to get a battery for invisible dog fence central unit?
The battery for the central unit that it uses when there is a power outage died and now the thing beeps once every 60 seconds. It was driving me crazy so I disconnected it but I was wondering where one would get a replacement. By the way, this is NOT for the collar, this is for the central unit with the blinking light.
I got the fence from Invisible FenceĀ®, I don’t believe the store we got it from is there anymore and am looking to order it online, however, their website does not seem to have any facilities for ordering it there.
Go to the same source that you got the collar or goggle the company on the web. Both will support the system and offer replacement parts.
