If you have hardwired alarms, it's best to have the same model for all, otherwise you can get unexplained alarms going off.
Vacuum out your alarms every 6 months (or more often if you have a lot of dust or spiders). Debris building up inside them can cause them to fail or alarms to go off inexplicably. If you're remodeling or doing something that will create a lot of dust, remove the alarm temporarily.
Ionization alarms are the ones that cause a lot of nuisance alarms (the ionization only alarms are the ones that tend to be dirt-cheap). Some have started recommending photoelectric only (or mostly photoelectric only and maybe one combined photoelectric/ionization). Keep ionization alarms out of areas near the kitchen and bathrooms (moisture from bathrooms can set the alarm off).
Buying CO monitors separate from fire alarms means that if one alarm mechanism goes bad, you don't have to replace the whole thing. Unfortunately, some states now require them to be combined - but if you own your own house, you can do what you want (unless you give an inspector some reason to require you meet the regulation, like remodeling).

Most alarm manufacturers like First Alert recommend against using rechargeable batteries to power your alarm. Rechargeable batteries lose charge faster and have a shorter runtime than standard batteries. The NFPA requires a standard amount of backup time that rechargeable batteries don't offer.
That's good to know. I wonder if that's applicable to all rechargeables, or just NiCd/NiMh types which are more common and usually rated at lesser voltage. In any event, the lithium ones I've put in are not lasting any less than alkalines.
Not necessarily applies to all, mine all including the ones with CO lasted 10+ years. I replaced Smoke+CO ones exactly after 10 year 3 months with the 2-pack from Costco. All others are still going good.
Check Costco for 2-pack smoke+CO.
Call them, they will replace for free minus five bucks shipping.

I also have some cheap Chinese Lecoolife battery detectors that I added for redundancy. And they are also working fine. But, they tend to be hyper-sensitive. So, I wouldn't recommend adding them anywhere near a kitchen.
Even if you have working, wired, battery backed smoke detectors, there's no harm - especially at $14, in adding a ten year battery backed smoke detector for redundancy just-in-case your existing one fails.
