See this thread on another forum, it probably isnât the batteries so much as way it monitors them.
I think it briefly gets a false message batteries are low and this remains on console until it resets at midnight.
You can reset it yourself by entering set up mode then exiting set up without changing anything.
Current theory suggests moisture is causing issues across (unused) contacts near the ISS battery.
I think thereâs more to it than that, maybe bugs or dust affect them too!
A reset of the console didnât cure the problem for me. However, I did remove the batteries from the ISS to check their voltage, which were almost full. I then gave everything a good clean whilst it was at ground level and replaced everything as it was. That was about 6 weeks ago and since then no more battery warnings, fingers crossed for the future. :roll:
Same issiue here and I have mine for only one month. I went through the reset suggestion and it corrected itself but I am not convinced it will not appear again.
So I changed the battery and applied the gel and reset the ISS by pressing the button and rebooted the console. The LED light flashed. I cam down off the roof and ISS and console are not communicating. Guess it is time to call Davis and find out what to do next.
I got to go with the solar panel as well. I also would call Davis as this seems to be the leading issue with their unit. Ask them what their solution is, I bet they have one.
I am noticing that on my battery powered stations that the batteries are being depleated quicker on my VP2⌠so I bought a fancier new battery and hopefully this will do the trickâŚ
I would make a log of when you put in the battery and when you replaced them. I also would call Davis next week , about Tuesday after the weekend holiday and ask them what is going on⌠I would call rather than email because they sometimes donât answer their email when they get behind for weeks.
I have 7 stations and the non -solar grind through the batteries. I had been putting in a standard battery that I got from the Battery Station in Missouri, they have a lithium that I have been using and I got to the end of my supply and decided to give BatteryJunction a shot as someone mentioned it here.
I opted for tht Titanium Innovations CR123A 3V Lithium Photo Battery 1400mah, http://www.batteryjunction.com/tpen-tcr123a-.html
I read the test results on the site as well as others and considering the fast drop out rate, I will give them a try anyway and see . I am home for the year, I think and if the battery is a bust, I can always upgrade.
I think it is the type or brand or country of manufacture that seems to have something to do with how quickly these batteries deplete and of course on a station that can produce interesting questions.
Thanks for the info. Itâll be interesting to hear how it goes. Itâs always hard to know how those high discharge current ratings relate to lifetime in a very low discharge application like the Davis sensors. I generally use the Panasonic ones.
Do the stand alone sensors use supercaps like the ISS etc?
no, they pull off the battery. Unless they have a solar panel like the wireless anenometer transmitter or the soil moisture sensor, they run off the battery.
I did have each of those solar panel units need new batteries, but considering that they have a super cap in them and the battery is for low solar days, and we have had them last month with 23 days of rainâŚI would guess that I will be replacing their batteries before long.
OK, I wondered if they still had a cap so that the battery doesnât see a pulse of current when it transmits, but I guess even that pulse is a very small current for these lithiums.
My ISS here faces west, and is shaded by a building, so it only rarely gets a direct view of the sun. Even so the battery usually goes a year or more.
I had to replace my ISS battery last winter and it went several winters⌠but it was colder than most and more snow and stuff, so the battery just wore out. not worried.,
That does solve a big problem, but with my case of the dreaded âTechno-Envyâ with all the other stations I have running, that would be a lot of cables to send out.
IF the batteries are a bust, I can go back to others, but the cost was about right. If you buy a cr123A at Wall mart⌠it is over $5.00 per battery⌠so the bulk is cheaper for me.
when the vp1 came out there were problems with the ISS board and they used a single wire for an antenna. They replaced in time the antenna and the iss board and how it was mounted. They also had problems with the uv sensor showing 0.3 units in the dark. They came up with all sorts of ideas,such as it was bounced radiation from a shopping mall miles away. Someone in germany figurd it out, it was a pin hole in the outer case. At night it drew in moisture as the sensor cooled and shorted the terminals. Davis corrected that by a software correction, modified the iss and so forth.
The VP2 needed a new solar panel on some units.
Over the years they have had issues with the ISS and I am certain the Vantage Vue might have been tested, but they might have faulty boards and solar panels.
I have a relative who worked for a leading radio communications equipment company (wonât mention the name). They developed it in the US, but it was manufactured in England. He spent many years of his life going over to the plant in England checking on quality control (His team developed the item and he is an engineer by the way). He said he found out the issue, the standards in manufacturing and quality control in the US was not the same as at that plant. Although it was monthly trips, he enjoyed that he got to keep his air miles and was able to send his parents and wife to a vacation far away fromwhere they lived . Africa? and that he found several pubs and eating places that were delightful. He also mastered driving on the wrong side of the road and feeling comfortable about it.
I am certain that you are blessed with one of the boards that the plant where they are made are not keen on quality control and there is a flaw. I would not only have them send you the ISS boards, but a new solar panel as well⌠The whole guts of the thing.
