Fluctuations in the backup battery reading are normal (between 70-100%).
However, if the backup battery drops below 50% there may be something else going on.
My backup battery would occasionally drop to 0% and I would get the annoying message. I finally came to the conclusion that my backup battery was not always maintaining a good contact in the battery compartment. To remedy the problem I simply took a very small piece of foam padding a inserted it under the backup battery compartment cover. This adds a small amount of downward pressure on the backup battery helping to insure that it maintains good contact. Seemed to do the trick for me as I haven't seen the annoying message since inserting the foam padding.
