Takes 6AA batteries, replaced them, making sure you remove, replace same sequence.
The faucet is back to working. Too much of a pain to attach back of cabinets, so just stood it against back wall behind hoses.

So if your Delta stops working in a year, fish out the battery pack, and load new batteries. Funny smoke detectors haven’t chirped, yet but dead batteries for faucets.

Had no idea it ran off batteries, guessing will have to add to yearly battery detector change dates.

Wow seems like much more trouble than its worth
