That's not very far off.

I don't have very many batteries in my house that will last 15 years in use. And many (such as car batteries) won't last that long in storage unless stored without acid added. (as new - before delivered to the auto parts store)

My friend with the solar/wind powered house has to change house batteries every decade or so.

The only batteries I know of that last decades in use are those on satellites and they are managed continuously and VERY, very carefully,
