ISS Battery

Chet:
I have just installed a new battery in my Vantage Vue but the console still says low battery transmitter. Last night, the Vue stopped getting transmissions. This morning, with strong sun light the Vue was transmitting. We have had several days of no sun shine. The Vue doesn?t charge the battery does it? Why would a new battery still show low transmission. I put conductivity paste on the battery ends.

After changing the battery in the ISS, you may still get a low battery alert until midnight of the day of the battery change, then the ISS and console will reset any alerts.

Just curious, do you remember how long your ISS battery lasted? 

xairbusdriver:
I think Blicj11 has the useful info! ThU5:-)

I just hope you didn't make the same mistake I did when I first installed my equipment. I put the battery in backwards!!! [banghead] [rolleyes2] [blush]

The 50-50-90 rule: Anytime I have a 50-50 chance of getting something right,
there's a 90% probability I'll get it wrong.

Don't have a Vue, but I think the only thing the Solar array charges is the capacitor. But, as I said, I'm oftin rong!

That conductivity paste probably makes it easier to get the battery out, it's very tight in my Pro. It might not hurt to double check that you may have used too much paste and accidentally connected either terminal to the circuitry. After all, that's two 50-50 chances!! cmu:-)

Dear Chet, Blick, X-Air, and WeatherCat station electricians,

It sound like you have a problem with the present battery.  X-Air could be correct, the battery is in backward, or it could be defective battery.  Try checking the voltage of the battery when there is very little sunshine while it is still in your Vantage Vue.  That will test the battery voltage under load.  A new 123 Lithium battery should produce over 3.2 volts.  If it doesn't it is defective.

As X-Air points out, Davis changed their designs between the Vantage Pro-1 and Vantage Pro-2.  The solar panel recharges a capacitor instead of a battery.  The battery is used only when there is no sun and the capacitor is discharged.

I've never done this and I'm not sure this is a good idea for this application.  If you continue to have problems, I suggest you remove the conductivity paste and see if that eliminates your problems.  The Davis hardware are designed to work without additional products like conductivity paste.

Cheers, Edouard

I too have the same problem as Chet.  I normally pay a local aerial erector ?25 to change the battery as the ISS is on a 20' pole above the roof Ridgeline on the gable end wall. However, this year I decided that I would sort out the problem of battery replacement by installing a fake battery connected  by cable to a CR123 mounted in an enclosure on the lintel above an upstairs window. I suspect that there is a problem with the contacts on the fake battery and I will have my to fork out another ?25 to drop it down and sort things out.

HOWEVER, here's the riddle. This morning I ran the "Test Power System"  before there was enough light to power the system and it reported the ISS transmitter was "Good" Huh? I then removed the CR123 from its mount and re-ran the test. Exactly the same - Tx Battery Stays "Good" How on earth can it be good when it's not even connected? Therefore I have to ask the community, what are these transmitters numbered 2 to 8 and how can a system power test say that all is good. In fact. how can a test of the ISS power system be run if there's no communication between it and the console? The attachments are later in the day but are exact replicas of the earlier tests. I have to admit to being very confused and I don't think that that is down to my advancing years.

Many thanks in anticipation,

A342
