In the rentals I manage, I have first alert smoke detectors. Can the new 10 year non replaceable battery detectors be mounted on the same mount. Or even is the mounting the same size?

Answer: 
Mount 4" away from the edge of the wall/ceiling, 12" is better. Not near window, door and air vent. Personally I attached to the wood stud, get a stud-finder.

Answer: 
Don't believe so. It's a battery pack, not a standard AA or 9v battery. Good for 10 years, or so they say.

Rated 3.4 out of 5 by 21 reviewers.
Rated 5.0 out of 5.0 by This is a great product. You don't have to change batteries every six months, which saves time and money. This is my second unit. I bought my first ten years ago and it's still working. October 25, 2016
Rated 2.0 out of 5.0 by Battery life too short Bought the original in 2014 but the smoke detector stared chirping like it had a weak battery after only 28 months. Far short of the expected 10 year life. October 18, 2016
Rated 5.0 out of 5.0 by good deal Easy to install tested and worked just as advertised February 23, 2016
Rated 5.0 out of 5.0 by A great purchase, no more need to replace batteries for ten year It would be better if they like every other manager does use screw holes rather than those wacky slots that you practically need 3 hands to install the base. A number of holes in different location so that it can be properly aligned. January 19, 2016
Rated 1.0 out of 5.0 by NOT A 10 YEAR BATTERY Installed this "10 year life" lithium battery alarm in July of 2013. It is September, 2015 and the stupid alarm is going off every 15 minutes because of low battery. Took the alarm off the wall and took the battery out. Will replace with another brand. Ridiculous. September 19, 2015
Rated 1.0 out of 5.0 by 10 year battery? So how come they only last 5 years? Perhaps it should be called a 5 year battery. September 12, 2015
Rated 1.0 out of 5.0 by bad battery I agree with other reviewers on the battery life. Ours lasted 3 months before the 10-year battery died and the unit started chirping at 5am-- we had bought this unit just so this wouldn't happen for some years. We'll be looking for another more reliable brand, or going back to the replaceable battery models. May 31, 2015
Rated 5.0 out of 5.0 by great easy to install handy to read looks reliable and dependable February 25, 2015
