A lady explained:
In my townhouse, I have an interconnected smoke alarm system that is powered, and which also uses 9-volt batteries. In the master bedroom on the third floor, the vaulted ceiling on which the smoke alarm is placed is very high, so it would require a tall ladder to change the battery. It’s thus a hassle to change the battery for that alarm. I’d like to get a very long-lasting 9-volt battery to put there so it won’t have to be changed as frequently. Got any ideas?
I would suggest getting a 10-year Lithium smoke alarm battery for the smoke detector on your vaulted ceiling, and maybe doing the same for the rest of your smoke detectors as well, while you’re at it!
Needless to say, it’s still important to regularly check for the low-battery alert since any battery can fail prematurely!
The Ultralife 10 year lithium UltraLife battery from batteries plus.com is $7.29.
The Ultralife 10 year lithium Smoke Detector battery from Amazon.com is $5.80. Just go to Amazon and in the search box type “Ultralife upvl”
Important: be sure the battery you are getting is listed for use in smoke detectors.
