DH is on his way to the store now as we have 5 bedrooms with smoke detectors going off every 30 minutes

so we have been replacing batteries.
My poor dex is freaking out and i keep taking him out to the car to sit in his doggie car seat. My girls do not freak out much but now DD is walking with tail down scared
any pointers on smoke detectors?
I know manufacturer said only a certain battery so we get those only but seriously frustrated tonight
