Another thought....Maybe that could cause the DL to loose some sort of settings for the battery voltages.
I am now pondering the price Pentax will charge.

The backup battery is needed to keep the internal clock running when the AA batteries are drained or when you take them out. With a dead backup battery, the camera will ask you to re-enter the time/date whenever you replace the AA batteries. Looks like the backup battery for the ISTDL can only be replaced by taking the camera apart. You can contact Pentax service to get a quote.
Does the camera still function with the battery warning? If it still works, you could just ignore the warning and continue to use the camera. The warning is probably a warning regarding the backup battery and not the AA batteries. Of course, now you would not have AA batteries warning.
Note that this should not cause the camera to lose its settings because the camera settings are usually stored in non-volatile memory.
