Davis Vantage Pro2 ISS

My ISS unit has been up for 1 year now. The manual suggests the replacement battery should last about 2 years. Is 2 years realistic for the Pro2 ISS in the south of the UK?

I would think so, mine last longer than 2 years.

I am not in the south of the UK but I changed my first VP2 ISS battery after 2 years because I thought I should, and then the next set was nearly 7 years when I decided to replace it.

We get good sunshine in the summer and much less in wintertime.

Enjoy,
Paul

Up here in the grim north my VP2 has been running for 10.5 years and I’ve changed the battery in the ISS probably no more than 3 times. Max 4.

I also have this problem, the battery only lasts about 10 months, the replacement is always a reputable brand and the internal contacts are clean and dry. The station is about 8 years old and 18 months ago I changed the capacitor.
So my thoughts are the solar panel is not producing the full out put and needs replacement. What should the output be ? I suspect 5v but cannot find that info. Has anyone found a replacement panel which would fit the Davis housing or alternatively a stand alone external panel.
My thoughts are that a third party panel with a slightly higher output would help to maintain the charge.

Any thoughts on this problem?
