I have lived in my current house for thirty years and have a monitored central alarm system. I also, in addition have battery operated local detectors that are in all the major living spaces. These are all the nine volt battery operated independent type that are the popular choice. Because of their age, I would like to replace them.I haven't looked recently, but in the past have noticed that they are offering a "ten year" type which you just replace the whole detector every then years and forget about the annual battery change. Anyone have any suggestions? "If you think everything's going to be alright, you don't understand the problem!"- Gutpile Charlie "A man's got to know his limitations" - Harry Callahan | ||

I just replaced all mine with the 10 year Lithium Ion battery type. Got them at Costco, 4x regular and 2x CO2 detectors, came in 2 packs. Don't know how good they are but they were simple to install! First Alert brand, I think the regular smoke 2 packs were $30 and the CO2 2 pack was $50. “People have to really suffer before they can risk doing what they love.” –Chuck Palahnuik Be harder to kill: https://preparefit.ck.page | |||

Just bought these to replace all the ones in my house that were original installation in 2003 when the house was built... Kidde i4618 Firex Hardwire Ionization Smoke Detector I like this one because the battery door is on the front so you don't have to remove the detector from the bracket to replace the battery.

Last two recommendations are for hardwired units. Did I misread OP? Are your existing ones battery only or hardwired? If battery only, this is what I always recommend to my customers. Kidde wireless interconnected SD. These give benefit of hardwired ones without the need to run expensive wiring. They can be combined with AC-DC models to expand coverage to bedrooms if you only have one SD per floor as well or to add coverage to workshops, craft rooms, or reloading rooms.

I remember putting up about 5 of these ten year battery units in my house and they all died within 2 years. Definitely hard wire them in if you have the infrastructure for that, and just keep changing your batteries annually. The ten year battery only units are JUNK. ______________________________________________________ Often times a very small man can cast a very large shadow | |||

I don't think it matters much on brand based on what I see when going to houses for false (and very occasionally real) alarms. The 10 year ones are probably the best compromise at the moment. But do pay attention to the type of detector and get what's appropriate for where you plan to put it. “So in war, the way is to avoid what is strong, and strike at what is weak.” | |||
