Useful for smoke alarms!

And they do last quite some time too.
Not a lot to say about a pair of 9v batteries, but I've not had any problems with Duracell for this purpose.
Whilst there are quite a few rechargeable 9v ones around you are better off with these as the rechargeable types are not suggested for use in devices such as this.
