Well, I pulled the 12V out of the Prius today. I checked to see if I could pull up the sticker somewhere, but it really doesn't look like anything is under there to add water. Could you clarify Bob? Here is the battery.
In the mean time, I have my mower hooked up providing 12v to the car to retain settings. I'm not sure what is all held in memory with 12v, but it was a quick operation.
