Questions & Answers

To have our rental properties up to code we need ten-year sealed lithium battery smoke detectors....

To have our rental properties up to code we need ten-year sealed lithium battery smoke detectors. Other brands say their batteries are sealed, but this one does not. Are they sealed?
Asked by: stacy
The description says that the battery is "removable". So, it is not sealed.

Battery Operated Long Life Lithium Smoke Alarm is rated 3.9 out of 5 by 15.
Rated 3 out of 5 by from Not 10 year detectors Maybe I should have read more closely. They said Lithium Battery and ten year warranty. It is a 9 volt replaceable lithium battery with a standard smoke detector. Not what I wanted so I returned the 10 I bought. They were probably fine if that's what you want. I felt it was a little deceiving in its wording.

Rated 5 out of 5 by from set it up and forget it. replaceable 10 year battery. lithium 9 volt style. just need to test once a year. we test twice a year on the time change dates. we just replaced the previous model with this one. it lasted 15 years with now working problems wanted the same thing. been in place now for 60 days with no issues. easy to install right in the place of the previous 10 year version.

Rated 1 out of 5 by from Picture does not represent the item I ordered 6 of these for my house. When they came they were clearly the wrong unit. No safety light and it comes with a lithium battery but no promise of 10 year life on the battery. I called the 800 number and the operator apologized and reordered the units for me. The new units came today and they are still missing the safety light and again no promise of 10 year battery life. I installed 2 of the units as I didn't want to go any longer without working smoke detectors in the house. They seem to work great but I really liked the idea of having a safety light and the price was reasonable. Not sure it I'll use the the other 4 yet or look for something different. Just wanted to let everyone know you won't be getting what you order if you order this item.

Rated 2 out of 5 by from Fussy battery tray The battery tray hinges out for battery installation. Unfortunately the detent is too high, and it is very hard to close the battery tray. The trick is to firmly press the battery down into the tray while simultaneously pushing the tray into the smoke alarm. Because the hush tab on the outside is also used to test the battery, it will NOT make a sound when you press it. It will illuminate a red light inside the alarm that indicates the battery is good. Don't throw the battery out thinking it has discharged. Also, there is no visible plus sign in the battery tray to indicate which way to orient the battery. Note the slightly larger slit in the battery tray wall - that is the slit the plus terminal goes through.
