(Un)fortunately there are things that are written down in standards, like the LED blinking behavior, that the manufacturers can not change if they want to legally sell the devices.
You can get a smoke alarm with 10 year battery life to reduce the likelihood of this happening. When all are purchased in one batch, you can then pretty much replace them all at once -- if first battery goes, next ones are soon to follow.
I got some unconventional looking ones from Jalo Helsinki [1] for my house. They work well and look good. However, I know some people working at Jalo, so my opinion is biased. There are several other long battery-life smoke alarms on the market from different manufacturers to choose from.

- kalleboo 9y agoYou could also just buy the Lithium 9V batteries instead of Alkaline and put in your regular smoke detector - same result https://www.amazon.com/dp/B01684J7P0 https://www.amazon.com/dp/B01684J7P0
- IndrekR 9y agoIf it runs on a standard 9V battery, then a very good option! Newer and smarter smoke detector chips are designed for 3V lithium-manganese dioxide batteries.
- wbl 9y agoCan you seriously not add a "Change Battery" LED next to it?
- IndrekR 9y agoIn theory, you can. However, the standards also mandate that the "annoying" function has to work at least few months after the battery is low. Adding an extra LED there will consume too much power.
