Smart move, especially in the smoke and CO alarms. A regular battery has
a different discharge curve and will give you lots of warning before
it's inoperative.

A rechargeable nicad or NiMh may go dead while you are out of the house
and don't the hear the few warning beeps.

I noticed a similar problem when I use NiMHs in a portable scanner. The
battery voltage drops so fast at the end of their discharge cycle, the
scanner's low battery alarm only beeps once. It's easy to miss it if
you're not paying attention.
