Smoke Detectors

Looking at using Tenergy 9 volt lithium non rechargeable batteries in my a.c. smoke detectors..I have some 14' ceilings so I would like to maximize the length of time between changes..Anyone using this battery or something similar?

I have a 10 year ultra long self life 9v smoke detector battery I got from Amazon. Battery is from China. I got through Amazon Vine. Got battery about a year ago and seems to work fine. Should qualify though that my smoke detector also runs off the circuit so that means the battery is more a backup than primary. But no chirps yet.
