How often do you have to change the battery?
824237
It came with a special battery for the switch, and for the 4 months I've owned it, I have not had to change the battery at all. The Receiver of course plugs into the wall so it needs not battery. I'm very happy with this purchase thus far!

I've had the product in use almost one month. It works great. I use it 2-4 times a day and it does not need batteries yet. Since it only uses battery power the instant the button is pushed and not continuously, I suspect it will last quite a long time.

I don't know the life span of the battery. I still have the same one that came with it when I bought it back in December. Maybe someone who has had one of these longer could give you a better idea about the battery life.

Sorry, Ryan, I have not had it long enough to know. I do not use it often, as it is in a small guest room/office.

I have this and similar products ( Leviton, Lutron etc) all over my apt, and the batteries last for years, since there sole purpose is to transmit a split-second signal to the base unit into which you've plugged your lamp or light. I haven't seen any difference in battery life based on the type of battery required: 12v, AAA, AA etc. I believe the batteries in one of my transmitters must be 3-4 years old, at least. Naturally if you turn a light on-off 50 times a day the battery life will be shortened, but I doubt most would use it more than 5-6 times a day. This particular unit is cheaper than the competition, and the smallish rocker switch is rather flimsy by comparison with those having the larger rockers.

I have had two of these units for 5 or more years and neither has required a battery change. The battery is in the switch only, not the part that plugs into the electric. I use one of them (the one in the pantry) several times a day so they must not use much power. The battery is only used for an instant when you switch it so should last for a very long time.

I installed a new one 11 November 2012 and haven't needed to change the battery yet. The previous similar one was good for approximately 9 years, I can't remember the exact date I initially installed the first device. The receiver plugs into the AC outlet and doesn't require a battery. You can purchase an additonal battery for the wall switch from Amazon as well...High Voltage 12v A23 23AE. There will be a battery supplied with your new purchase.

I have had mine since early December and have not had any issues with it and I have not yet changed the battery.

I bought the first one 2 years ago, so far the battery is working well. My brother charges it once a month and uses it every other day! Not yet need change the battery, but I guess when ist is gone, the only way is to replace to a new one, after all, it is only 20 dollers after sale.

I've had it over a year. I use it at least once a day, usually more. Have not changed them yet.

I've had mine almost a year and haven't had to change the batteries yet. Thinking about getting another!

I bought it in July 2014 and have not replaced the batteries yet. But I do not run it all the time just occasionally. I have a water barrel with few goldfish in it and just run it for about 30 min. at a time, maybe twice a week. Hope that helps some.

In the Instructions it says when to change, I think once a year under normal use.

I went to the manufactures website and they recommend replacing the battery twice a year. I find replacing it once a year works well.

I have never changed mine. I have had to change the battery once in over a year.

I have not had to change the battery every 14 days. I would probably change them monthly though for my own piece of mind.

I just changed the battery. It depends on usage. I have on average ran 3-4 times per week of about an hour. It lasts about 5 months, and is super easy to switch :-) I also use it as a watch every day. Hope this comment helps.

It varies, but usually, they tell you to replace any battery after one year or if you notice your items are not working as great - then it is time to change.

We gave this to my daughter in March and have only changed the batteries once. She goes back and forth between using it a lot and then she doesn't use it for a while.

I generally have to change mine every three to six months, but I use this keyboard everyday for a solid 4-8 hours of typing. I wore the letters off the keys before I had to change the batteries for the first time. Hope that helps! I LOVE this keyboard!

From previous experience I had to change mine every 12 months. The nice feature about these units is that you can change the batterywithout taking the unit down from the ceiling. The little pop open door on the face makes changing batteries a snap !

The manual says to change the batteries at least once a year as a good safety measure, or at the same time as you change your clocks for daylight saving time. The alarm has a simple way to test it, and the manual recommends doing so once a week.
