How often do the batteries have to be changed?

That will depend on how often you activate the voice, but my mother uses hers several times a day and the batteries last over a year.

My grandmother has been using quite regularly and the batteries are holding up fine. She has been using it now for two weeks.

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.

We use it every night plus naps snd we change the batteries every couple of months. I actually can't remember the last time we changed them!

It really depends on how often it is activated. I have had mine up for over a monthsand have cats that activate it. I have not had to change the batteries yet.

Quite a while. I have owned this for well over a year now, and I have only replaced the batteries once.

I have had mine for 3 months and have used it once or twice a day since then. I just changed the batteries in it today. So depending on you use I would say 2 to 3 months.

We purchased this for my mother in law who lives in an assisted living home. With constant use we were changing the batteries about every two weeks.

After about a year the batteries were still working fine. That said, I'm not sure how long they'll actually last because, for SAFETY SAKE, it is recommended you replace batteries ONCE A YEAR regardless if they're still working or not. I change mine every fall around Daylight Savings Time. (I keep the partially used up batteries, in a marked "Used" baggie, for toys or other odd uses; but never for smoke alarms!) Hope this helps.

Battery life is fine, I've only had to actually replace them one time since my purchase. Checked the mouse with new batteries to make sure the issues weren't battery related, but they persisted so I stuck the old batteries back inside every time. So one battery change after ~4.5 months of fairly heavy daily use.

I couldn't say exactly, but definitely a long time! I don't change my battery often. I have 3 batteries: 2 Wasabi and 1 Lumix, and I haven't noticed a difference between them. They're always full-power according to the camera indicator when I switch to a new one. I'd say on average I change my battery every couple weeks, but the one I randomly replace it with may have been sitting a month at least.

I can only speak from our experience; my son is 2 months old and we have used it every night since his birth (and sometimes during the day), and have not yet had to change the batteries. :)

I change mine every 2-3 years, depending how much you use it. I use it about once a month for the large kitchen area.

You are better off just getting a new one when needed because you have to be careful on how and where you store them. Best rule of thumb is to change them every 3 years with a fresh new battery.

I change mine every 6 months. I have pets. You may be able to go longer if you don't have pets.

I changed the batteries on mine after more than a year of use; the stock batteries were just generic. I haven't changed them again after replacing it with good batteries over a year ago. I use mine about three to four times a week for several hours at a time. Just switch off when you're not using it.

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 have one that I've been using for almost three years and it's still going strong. Just change the batteries when it starts getting sluggish or acting weird and it'll come back to life.
