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.

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?

Rated 3.4 out of 5 by 19 reviewers.
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
Rated 4.0 out of 5.0 by Reliable alarm, but battery life is highly variable. I have four of these installed, and one just gave me the beep alert that the batteries had died, This, after 3 years and 2 months. The others seem to be going along fine, testing okay and still rendering loud and clear alarm signals. So I conclude that the batteries in these alarms are a lot like light bulbs - they can last a long time, or go out prematurely - and you never know. It would probably be more honest if this product was billed as an an "UP TO 10 year alarm." Still, I don't mind replacing after over three years. September 12, 2013
Rated 5.0 out of 5.0 by Love the long batterie life I purchased these smoke alarms for fire prevention week in the Borough so the fire company could give them out to the residents. I purchased them for three reasons. The first being how important it is for every home to have smoke alarms, the second because they had a ten year battery life and that was perfect as a lot of people do not check or change their batteries. The third reason is the rating that fire marshals gave them. I am going to buy these for my home now that I know about them. September 24, 2013
