Its time for replacement. I'd like one with a lifetime battery any linked (not networked but if one goes off both go off). I need two and my house is not hardwired for smoke detectors
Ideally I'd like CO2 detection too.
I can't seem to find any that meet all my requirements can anyone recommend one?

Summary needs:
Linked-both go off
CO2 Detection
10 year or similar long life battery

Have you looked at Nest Protect? It uses 6 AA batteries which are supposed to last several years, they link to each other, have CO2 detection, and can send alerts to your phone.

I've got two Kidde wired smoke detectors and 2 Nest Protect battery-powered units as well. I'll probably eventually replace the Kidde units with wire Nest Protects. They're pricey but have a lot of features.

Funny I just picked up two today, I originally was afraid about poor detection rates but Gen 2 fixed that. They weren't that much more expensive and they'll communicate with my thermostat to shut off the furnace if CO2 gets too high. That was the selling feature particularly for the pets.

I bought some "First Alert" ones and it comes with a 10 year lithium battery, it looks like a 9 volt, it might actually be a 9 volt, but it's lithium and suposedly good for 10 years. When it dies you change the whole detector as the detectors themselves have a limited life (though in my experience they seem to last much longer).

Been meaning to buy a bunch that all run on same voltage, then hard wire them to a central battery backed power supply and signal wire, then tie it into my home automation, but have not gotten around to experimenting with them yet. Basically it would be nice to have it send me an email on my phone (alerts me) if there's a fire and I'm away. After my parent's house recently having a fire it also got me thinking it would not be a bad idea to have smoke detectors in the eves of the house, outside and in the attic. A lot of fires start outside and by the time you realize your house is on fire there is way more damage than if you had caught it faster. Had my dad not gotten woken up by the dishwasher starting, and a loud bang outside, I think the result would have been grim... I should probably put one in the garage too.

I have one detector that is linked to my alarm system though, but those are $100 a pop if I want more.
