Good enough for me. I had an alkaline 9-volt backup battery go dead in an alarm clock earlier this year, but no mess. The 9-volt lithiums I see would probably be overkill. I have some remotes that use 9-volt batteries. One theory of mine is that they could be made to more stringent standards (the outer shell) because of their use in smoke detectors.
