I bought one of these it was bad. Needing a battery right away, I purchased another. However, I warrantied the first one and was given a brand new unit. It's still boxed and sealed. It's yours for $100 shipped. It's part #BTL14A240C.

I found this while messing around. It nice to see there's plenty of water again. It's just too bad there's so much damage to go along with it. https://cdec.water.ca.gov/cdecapp/resapp/getResGraphsMain.action
And here's the snow pack levels too...
If you are concerned about corrosion getting into the connectors, put some dielectric grease in them. Take the connectors apart, squirt some in, and that will keep the corrosion at bay. You will still need to check on them every so often though.
