Hi all,
After 10 years of flawless service, my ISS stopped sending signal, and every time i replaced the battery it was exhausted within days.
As i am living in Iceland, we get not much sun from august to march and therefor i have had to replace the CR123 battery twice a year... until now maybe.
My super capacitor died and when i start working on replacing the capacitor i read on some articles that the standard capacitor is 2.7 v 10F, and it is possible to put an 50F capacitor, and more. As i have a European model, i can have 2 capacitors. So i ordered 2x 2.7 50F capacitors and began to upgrade. It was an quite easy job, just a little bit soldering and my weather-station has working very nice after the upgrade.
I have here attached photos from my ISS, with the blown capacitor and the steps until it was ready.
Hope this will help out others in upgrading their ISS and fixing them.
Here is my ISS
After i remove the cover
Here is the blown Super Capacitor

New capacitors in place and ready for soldering
And this is how ISS with 2x 50F capacitors looks like.
