Davis Weather Station batteries

When I'm at the local drug store, the place where I can buy weird batteries, I can never remember the number of the battery used in the Vantage Vue Instrument Cluster (Davis #6357)... So this webpage will help me, and perhaps you as well!

It's the CR123, aka DL123.

I've gotten as much as 4 years of life in this application. As the system does return this information to you, it's safe to simply wait until you're warned that it needs replacing.

I don't recall absolutely that the base station shows it, but I'm sure it shows up in the "commentary" area.
The Cumulus console on the computer always shows it in the display; near the bottom left it says:
"TX Battery Status: 1-ok 2-ok" etc.
Your lone weather station is #1, and it's battery status will be "LOW" instead of "ok".
Also note that the Vintners.Net PMI program - if properly set up, and you are the administrator of the station - will have a "manage station" option. This page will show the system parameters; the default configuration has "#txbattery" which shows the same TX status line described above.
And, assuming the above portion is working, PMI will notify you via email/txt if the TX status line changes - assuming your preferences are set for "use txt" and/or "use email".

Lastly, FYI, the base station (Davis #6351) takes 3 standard "C" batteries.
This may be indicated in the base station commentary area, I don't recall for sure.
This does NOT show on the web-based console screen.
As above, this shows up in the PMI program under the "manage station" option as the "#battery" value (assuming all is set up properly, see "sysparmsT.htm" in Client install).
