Person means 10-year battery to meet certain new state requirements, such as that in crazy California.

While the new CA law means to protect residents from dead batteries each year that aren't replaced, 10-year batteries can introduce their own issues.

For example, residents may completely forget to maintain and test the alarm frequently reach year. A broken or no-power fire alarm is worthless.

Also, what's the actual failure rate and reliability of a ten year battery? Regular batteries are very predictable and reliable, but has anyone seriously tested and researched over 10 years the reliability of such batteries for use in these detectors? Voltage levels continue to drop over time for any battery.

Cost.
$5-10 detectors now go for $15-40 in CA.
Two 9V batteries go for $0.99 at the dollar store.
Many lower income who could easily put a detector in every room may go with fewer, or none. (Eg. Living room, kitchen, garage, 3 bedrooms, 2 bathrooms = 8 detectors. $40 for non-10 year, $120 for 10-year)

Cheaper detectors can be replaced to meet new code standards at a lower cost; ten year detectors? Owners may not update for a decade due to the cost.

Dust? Blockage? Ten years, no maintenance. What if the detection ports get blocked by dust etc? At least with 1 year batteries, you are reminded to check and test.

IMO, better to be reminded at least yearly by low battery beeps coming from 8+ detectors for you to replace and test the alarms vs simply forgetting about them for a decade.
At the same cost as a new ten year, older ones could even combine fire and CO.
...

It's similar to the crazy Toasters. 3-prong instead of two, Electronic cancel instead of mechanical. Etc. All supposedly to prevent fires, but realistically? You've got more clogged dryers. More expensive, not truly safer because when electronics fail, often at rates higher than mechanical triggers, you still have a fire and additional issues exist.

Normals don't realize this but there's a significant portion of the population that is so unintelligent and out of it that they can live with the low battery warning chirp on these for years. A beep every 35 seconds. It's unbelievable but it's true. That said I was just thinking I need another one of these. Thanks.

Every time I try buying a 10 year smoke detector from Amazon, it always says they can't ship to CA. I picked this one up last time, will pick another up this time.

I assume I'd I get this one I would also have to get a separate carbon monoxide one. Or is there a better option.
