    I bought this for my mother's home. This is the second one I have bought and the last one did last nearly 10 years like advertised. In the long run this is much less expensive than replacing a 9volt battery every 6 months like in most smoke detectors.

    This is a great product for anyone who forgets to change the batteries in their smoke detectors.This smoke detector has a battery that will last 10 years...and when I broil steaks and the alarm goes off..I can push the button to shut it off for a whle. I used to stand and fan the old detector.

    needed smoke alarms for bedrooms to fulfill code requirements. This alarm had a 10 year battery included which means that I should not have to replace it twice a year. Well worth the money

    IF THAT IS SO, WHY DOES THIS ONE HAVE AN EASY ACCESS BATTERY DRAWER?
    by an anonymous customer 2/25/2009
    4 answers
    • A. Once the battery pack is inserted, it cannot be removed,At the end of the 10 years, you would have to buy another smoke alarm to replace it. It is recommended that you de-activate the alarm buy reading the instructions on the back of the alarm, before throwing away, it isn't deactivated by removing the battery pack.

    • A. I am a Fire Official, You need to REPLACE your SMOKE DETECTORS EVERY 10 YEARS without question. IF you do not know how old they are REPLACE THEM. ALMOST all Fire Officials across the U.S. are recommending the use of PHOTOELECTRIC SMOKE DETECTORS in your home. Learn More Here...

    • A. according to the IMAGE of this product, the product itself states ON it that the battery is sealed and to replace the ALARM after 10 years.

    • A. Because the lithium batteries last ten years and it is the batteries that need to be replaced every ten years, not the smoke alarm. It is a lot cheaper to buy lithium batteries than it is to buy new smoke alarms.
