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.
