I try to replace the battery during the day (super cap well charged) and just pull the old one out & fit the new.
Two batteries in 2 years ain't bad. On my main IIS I tend to change the battery around October as the shorter days are drawing in, just to be on the safe side through the winter. :wink:

all you have to do is just replace the battery.  The console eventually resets itself at midnight, OR... you can put it into the setup mode, and take it back out and that will reset the console.

Flatline?  you mean all dashes on the console for direction.   I'd contact Davis.   I am betting they have their units not built in the US and some bad parts.  should last longer than that.     Sorry to hear that it is giving you headaches especially since we are both getting into the interesting weather time.

I never got any low battery warnings on the console but I think I changed the battery for the first time after 3 years as I thought it was well overdue lol. The current one has been in for over 2 years. I always use Duracell.

By flatlining I mean on my WD window via the Davis Envoy.  As soon as the sun started warming up the ISS solar panel, data tarted streaming again.  I would assume this means a bad battery.

I installed a battery of a bit better voltage and, as I said, data started streaming.  I then removed it to have it replaced (3 year warranty) and data continued streaming from the solar panel.  I assume this points to a good Super Cap.  Stuck a fresh battery in there.  Seems like they're going for a year.

I got a low ISS battery note last summer, so I put in a new battery and went on.  Earlier this month I came home and saw the outside sensors dashed out.  So I hoof out, take off the cover and flip the test switch up and no led light.  I put in a new battery and it flashes like mad.  So   put everything back and figured it was a bad super cap. I didn't have time to fiddle with replacing the cap so I ordered a new board from Archer Trading.  They sent the board, antenna and case, all I had to do is go out, take off the ISS, fish the cables in and out of the abnormally small  access area . I finished as the sun was setting, so I put back in the battery to run over night the next day, I went out and put in a fresh battery and we are done.   

When the weather gets better go out and take off the solar panel, and unscrew (phillips head) the four screws under the plastic dome that hides the components and look at the supercap to see if it is leaking or not. If it is, then you could order a new supercap and have it ready to replace when you have the chance.

 I am thinking that since Davis has a video on their support site on how to remove this unit and replace it, the death of the supercap is more prevalent than we suspect.   In the instructions on replacing it , the warning that  the leads must be bent away from the bottom of the  supercap case and that looking at the picture attached it isn't.  Then Davis recommends putting in a spacer between the replacement supercap and the circuit board to take a strain off the base, indicates to me that they have a quality control problem when the boards are made.

In any case, now I have two ISS boards, ordered the supercap from Archer Trading post, it has been shipped  and on their site they have the same recommendation to protect the supercap http://www.archertradingpost.com/atp/index.php?main_page=product_info&cPath=1_6_9&products_id=68

I checked into my station at about 6:40am today to find the Number 2 station offline, needs battery, so I had a spare, thanks Santa, installed, corrected the dbase to fix the graphs and headed for Manzanillo, 86 and hazy? - but, I wanted to take pics, oh well. And, as I passed the volcano at Colima I couldn't even see it for the haze and clouds, not what I was expecting in my stocking, thanks Santa?

I am glad that I am not the only one who saw that and loved it?

Unless the super cap is poaching  I figure 2 to 3 years. If the summer has been too hot I sometimes just replace the battery in a year .   But I buy the batteries in bulk, about 1.50 a battery..

Panasonic CR123a, 1550 mah, 3.0V Lithium.

Probably a dumb question.. these batteries do not appear to be re-chargable.. does the Vantage Pro not recharge the batteries with the solar? Does it just use the solar when it can, and the battery the rest of the time?

I've had the same battery in my Vantage Pro for at least 10 years.. how is that possible if the battery is not re-charging?

Thanks!

The solar panel charges the super capacitor which runs the ISS and stores energy for use when there is no solar. With no solar, and no remaining stored solar, the battery is the source of power. You are fortunate to be in a very sunny location, a ISS located in the U.K. for instance will be using the battery a lot more. The ISS power consumption is very low, it just takes a quick little sip of power each 2.5 seconds. You are fortunate to be in a very sunny location, an ISS located in the U.K. for instance will be using the battery a lot more. Having said all that, nothing lasts forever so with the shorter winter days upon us I strongly suggest you replace the battery now before it finally expires. If you have a meter please post the voltage of the old battery  :)
