Eufycam2 not working after almost 2 years

I have a Eufycam2 I bought as a set. The cameras have been good and even bought an add on camera. My Eufycam which sat in the shade of my back porch for these 2 years (except for charging every 4-6 months) seems to not last 2 years under the indirect hot and cold of Texas weather.
Has anyone experienced this?
I’m inclined to avoid battery cameras moving forward for this reason and buy a system of similar kind with local storage.
Thanks for sharing your experiences.

PS I do have a ticket open with Eufy support but I don’t think they’ll find much.
