How often should batteries be changed?

I use them May through September, and usually go through about three sets of batteries during that time. Last year, I did connect them directly to electric with extension cords, because while I was on vacation, and the batteries failed, and the deer ate very well for a week.

Sorry - can't answer the device didn't work animals kept coming and we threw it away before they ran out.

I couldn't say since both of mine were running on charger, the last one is anyway.

I don't know, I hooked mine up to 110 volt outlet. Guessing I'd say often, based on the wattage required to support the loud noises it makes. Mine works very well at keeping birds from nesting under our deck, which we could not control by any other means.

I keep one battery on the charger at all times, and switch them once every other day or so. As long as the battery will not be sitting there for several weeks, it will be fine.

You can use it as many times as you want. The battery is the only thing that needs to be replaced. My battery lasted roughly 2 months of HEAVY usage. The device will let you know that the battery is low when maybe 5% charge is remaining.

Never had a problem. I had my first one for years, change battery about twice a year . Purchased new one November no problem. Sorry your having trouble.

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

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.

Do not change batteries enough for it to be a problem. Probably depends on the brand. Maybe once a year

It depends...were the batteries alkaline batteries? Alkaline batteries (which I recommend) should last 3-4 months under normal use, brushing 2-3 times a day. If the batteries you used were not alkaline or lithium batteries, then having the batteries die after a month would be normal if you brush multiple times a day.

Battery life is pretty good (I think). I don't actually keep a record of battery changes, but my impression is that I must change batteries about every 6 months. I carry an extra in my golf bag because unlike someone else said, there seems to be little warning that it is about to quit.

I've had this remote for over two years. I saw the light and went the rechargeable route. I can usually go 7-8 weeks between battery changes. If you use the backlight a lot it seems to eat batteries faster. I do know if you have one bad or low battery it will tell you to change batteries quicker. Make sure that all four batteries are fresh.

My first battery change was about two months in, and that's with heavy use and the screen/button illumination always on. I turned off the auto-on settings and stretched it out a couple more months. Of course, I use it constantly throughout the day and evening.

I put new batteries in last year after I first installed the lights. I am still using the same batteries. Usually I leave mine on for about 2 hours at a time. I've probably used mine 6-7 times so far with the same batteries.

It depends upon the type of batteries you use and the number of pictures you take as well as how many times you have reviewed your pictures. I never have gone more than 6 months without replacing batteries in my SX120.

I use mine about once a month and have not had to change the batteries yet. I have them in for the past 4 months. Great unit!!!!!

I change mine about every 6 months, but I only use it at work. It doesn't get everyday or all day use.

My recent experience was: first set fresh batteries - just under one hour, second set fresh batteries - one hour 10 minutes. So, it will vary within a 10-15 minute range.
