Smoke alarms

To whom it may concern,
My house is in White Plains , New York. I would like to upgrade our smoke system from using 9V batteries to something better. How should I go about? This smoke system is linked to alarm system in the house. I am sick and tired of changing batteries every year. The batteries have to be the same date, same brand or the system would beep, very hassle . Year after year.
I think it’s time to look for better options.

Thank you,
Victoria Yeung.
