Do these still need a mains supply, if so it might not always be so simple.
If not then radio interlinked wont last anywhere near 10 years despite any claims otherwise. 1 year maybe, 10 years no way hosea.
Years ago I would have agreed on the battery issue.
Now the batteries and the alarm technology are much better, however I would not install something like Fire Angel (they had a product recall a few years ago as 10 year batteries lasted 1.5 years)
On the other side I install Aico battery interlinked alarms and have had almost no failures, the failure rate is less than 0.05% (we have installed lots), we tend to get the client to buy them direct from the wholesaler to keep our turnover down
