How long do they last?

I used them for about 2 months and they didn't seem to work at all. I had mice and ants in my kitchen, and neither was affected, it seems.

No clue but they don't work. I put three in each room of an 1000sq. Ft. Condo and they have done nothing!

I does last for a long time....I bought mine in Feb. and it is still going strong...normally they are supposed to last 50,000 hours and I am still counting.

I can't say exactly how long they last, but it's decent. long enough that I don't remember changing them

They last quite a while. I mainly use them for my son's wireless remote for his Xbox 360, he plays everyday, somedays he plays allday and on average we usually have to recharge them every 3-4 months. I found them to be better than an OEM battery we've had.

They last a normal length of time. Do not recall how many hours. More importantly is that the light is not very strong. Depends what you need them for but they do not illuminate very much.

Keep 'em clean and they should last much longer. I'm at the 6 month point right now and they are still working really well.

Exactly 167 years, 5 months, 28 days, 4 hours, 37 minutes.I'm kidding. I have no idea, but it would seem that with proper care they should last a few years. :)

Some have lasted me a full 2 days. but some not even a day. So its a flip of a coin..

As long as they are not open they last awhile. Even if opened, if closed tight will last.

I don't know how often you use them but I have had some for up to 6 months and haven't any trouble with them. Hope this has been helpful. Thanks Bert

I'm sure they would last beyond a year. I've had mine for maybe 6-8 months and some have changed shape a little, but otherwise they are all perfectly fine!

Depends if you purchased New or Old or Refurbished or so.They do last 3-5 years depending on how well they are looked after.

I've only had mine for about 2 months, so I can't speak for how long they last. Fortunately, no issues thus far with them.

It depends on if you're using them continuously. I would say you can get about 8-10 hours (though this varies). You can extend the life by removing the batteries when you don't need to use them. You can also buy replacement batteries, but they tend to be expensive so I would recommend buying new ones.

These last as long as the higher priced ones. Being an obsessive record keeper, I can tell you exactly how long they last. I get 7 to 10 days from them, in the summer, and 5 to 7 days in the winter. No clue why there is a difference with the season, unless it is due to heat being on. (I have 2 Siemens hearing aids.)

If kept in a cool, humid free area they can last for years. If I remember correctly I'm thinking 10 years +/- a year or two.

At least a few months. I use them too quickly to find out, but I used a leftover box after about three months and they were good as new.
