How long does a set of batteries last? Alkaline or lithium
1289226
Regular batteries (AA I think) and they last a pretty long time. I've had my first set about two years now and maybe have replaced batteries once, maybe twice. Wear them an average of 9 -12 hours a week.

Have had a set of batteries (alkaline) in, for over a year, and it still functions fine. However, I would suggest changing them every year, or so. Beats coming home to a dark porch/front door.

I'll need to qualify my response by saying I do not need this machine every night, so it's not in constant use; I also use the timer feature (normally I pick the 60 min. setting). Having said that - I'm still on the first set of alkaline batteries since I purchased it in March 2013. If I had to guesstimate, I'd say you should probably get at LEAST a month straight out of nightly one-hour usage.

I've now had my 550 for 2 years. My batteries last at least 2-3 months before needing to be changed, and this is with the light set to stay on for the longest possible time. I do use Ni-mh batteries in it though, which may last longer than alkalines.

AA batteries. I use these Lithium AA cells: Energizer Ultimate Lithium AA Batteries, World's Longest Lasting Battery for High-Tech Devices, 8 count

a photo shop expert told me just this weekend, that the alkaline batteries fade fast, and some of them have less power if they have been on the hook or shelf for a while. One step up is to buy the lithium batteries, but that would probably be more expensive in the long run that buying rechargable batteries (which is the best option).

The first set of Duracell batteries in one light on our front porch (activated a few times a night on average) lasted for four years. I had to replace them earlier this year so i don't know how long these second set will last.

AA batteries. Last about a month in the kitchen due to lots of traffic and sensitive lotion sensor...but last a long time in the spare bathroom!! Excellent!

In my experience, these last as long as the battery - barring accidental damage. The older models had a user replaceable battery - not too easy with these newer models. If you care properly for the Li-ion battery, it may last 3-4 years - or even longer, depending on use. Of course, YMMV

I use lithium batteries and I'm still on my initial set after several months of use.

lithium and alkaline batteries are each suited for particular uses. Lithium batteries are more suited for heavy duty use. you might want to pose this question to the manufacturer on their website as to why this is a requirement.,

No. This listing says the batteries expire in March 2016. Alkalines have a 5 year shelf life, and these are at the end of their shelf life. This is why they are so reasonably priced as far as 9V batteries go.

I can speak to the battery life. I installed the base unit and one remote (outside) on 2012 Dec 2. I'd ordered lithium batteries for it (good for temperature extremes), but they hadn't arrived yet, so I loaded them up with some AA Duracell alkaline batteries I had. 472 days later, the main unit started losing contact with the remote, and I noticed its low battery indicator was on. The remote was still going strong. I replaced the alkaline batteries in both units with the lithium batteries that I'd ordered back in 2012. That works out to 15 months (over two winters and one summer) on just regular alkaline batteries. I'm expecting longer life from the lithiums.

It depends on the type of battery. One year is about right for regular 9V battery. Alkaline battery will last longer.

I'm using lithium-iron batteries, but just on my first set so I don't know how long they're going to last The camera is a bit of a battery pig and the question isn't how many photos can be taken, but rather, how long can the camera be on for a set of batteries, because it uses battery power the our whole time it's turned on. I'm considering buying a couple sets of rechargeable lithium-ion batteries.

The batteries are the part with a temperature range--lithium batteries will function in freezing conditions whereas regular alkaline batteries will not. One of these has worked in an unheated attic with lithium long-life batteries installed.
