In addition, does each alarm (ionization and photoelectric) have a separate battery? (i.e., does pkg include TWO lithium batteries, one for each alarm, or just one lithium battery?)

Thank you.

Two Units per package!
The batteries are already installed in the units. Just take the units out of the package and hang. They are ready to go!

Answer: 
As it states on the product overview section and in the image, it states/shows that it carries one ionization and one photoelectric alarm.
Ionization is for flaming fires and photoelectric are for slower, smoldering fires.
The lithium batteries are self-sealed in each unit, which means you never have to replace them during the entire life of the alarms, which is 10 years.

Answer: 
Hello. In reference to your question, in searching consumerreports.org , we found only that they have tested the PI9000, which is the previous version. The main differences between the PI9000 and the PI9010 is that the PI9010 does NOT have the alarm memory mode where it tells you if it had gone off in the past, and in HUSH mode, the PI9010 flashes every 10 seconds instead of every 2 seconds.

Rated 3.0 out of 5 by 9 reviewers.
Rated 4.0 out of 5.0 by Smoke Alarm Replacement Two different mounts, but was able to work around. replaced existing alarm system. September 6, 2016
Rated 3.0 out of 5.0 by average key is that it was properly priced given the product quality. June 28, 2016
Rated 2.0 out of 5.0 by Don't buy, false alarms. One of these alarms, I'm guessing the "ionization" one constantly sets off when steam from the shower comes out of the bathroom into the hall way. It also sets off every time the AC turns on and the temperature in the area of detector changes. April 21, 2016
Rated 2.0 out of 5.0 by They make it confusing with the two different types. I noticed in the store that the two smoke alarms in the package weren't the same as each other. I asked a Home Depot associate what the difference between them was, and he didn't know either. We spent a bunch of time scrutinizing the package to figure out that one is ionization and the other is photoelectric. Of course, we still didn't know what the significance of that was, and there was nothing on the package to explain it. I decided to buy it, and expected to be enlightened when I got home and read the instructions. It wasn't easy to find an explanation of the difference in the instructions. You have to read all of the instructions carefully and patiently for a really long time until you accidentally stumble upon it. Buried deep within "Limitations of Smoke Alarms" section they tell you that ionization detects fast flaming fires, and photoelectric detects smoldering fires. But them I'm still left wondering, where in my house should I install one type of alarm and where in the house should I install the other? The only other thing they say on the subject (still buried deep within "Limitations of Smoke Alarms" section) is that since fires are unpredictable, they recommend you install both. Are they saying that I should install one of each kind, side-by-side, in every recommended location in the house? If not, I still don't know how to decide where to put one and where to put the other. If they're going to sell these things together as a package, you would think they would offer some guidance. Another problem is the crummy labeling. The labels are embossed in the surface of the plastic. Beige lettering on a beige background. So unless you have good eyes and good lighting, you can't even tell that the buttons have labels, much less what the labels say. With the thing mounted way up on the ceiling, that's a problem. Then there's the mounting systems. The ionization one has a normal mounting ring like most smoke alarms But the photoelectric uses this 1½" center disk. If you have drywall, you use a provided plastic spiral anchor to screw the center of the disk to the ceiling. Then, when you have to take the smoke alarm down to paint or something, the spiral anchor could unintentionally unscrew when you rotate the smoke alarm to remove it. If you have lathe-and-plaster, you have to drill three closely-spaced holes to put in three closely-spaced anchors. If your plaster is old and brittle, the plaster between the three holes can crumble and fall out, turning your three closely-spaced holes into one large gaping hole for you to have to fix. Why didn't they use the same large mounting ring they used on the other one? February 10, 2016
Rated 3.0 out of 5.0 by I'll let you know if I have a fire within the next 10 years This is a Smoke detector and I hope it works when needed. January 12, 2016
Rated 4.0 out of 5.0 by No Batteries!!!! I have 12 rental units and the tenants will never replace the batteries. These babies last 10 years!!! August 4, 2015
Rated 4.0 out of 5.0 by Great product, especially the two-pack! I install these gratis in the homes of low income folks and appreciate the chance to buy them in 2- packs at a reduced cost. I'd buy them in 6 packs for even better savings. They mount easily, especially when I use the right masonry bit size to drill the holes! Haven't had a "dud" yet so quality is consistent. I'm not fond of the mounting plate. I work in old properties where there is often a soft plaster coat on the walls/ceilings and the torque it takes to engage the mounts can gouge the mounting hole out. Which leaves me using the alternative mounting holes which are much closer together (compared to a rectangular plastic plate, for instance). So I need to be more cautious using the round mounting plates and since I'm part of a large volunteer base doing this type of job, I start wondering about the guys who hurry their work and need something a little more toward foolproof mounting :0) Ah, well, it's a good price and a good product. We use the 10 year battery units precisely to ensure that our elderly clients won't be losing their batteries to younger relatives with battery powered toys, etc. The plastic embossed notations on the units could be easier to read. The lettering is very small font and there's no contrast with the case color. That's an improvement I'd make to serve the elderly for whom I'm working when they deal with these units. In fairness, I haven't seen competing products that are easier to read, so this would be an improvement that might be profitable in the long run. August 4, 2015
Rated 4.0 out of 5.0 by ONE OF EACH You get one of each type of smoke alarms. I mistakenly thought you got two smoke alarms that sensed both types. Since they were going into two rooms right next to each other that turned out to be fine. One of the alarms had the single mounting disk that is easy to install, while the other had a ring bracket which is a little more difficult to install, especially on my plaster ceilings.
