I'm planning to use these in a wireless doorbell chime. I'm wondering if anyone has any thoughts on how long these will last between charges?

I wasn't really impressed with these batteries. I use a fan at work every day that need (in some fans) 2 and other 4 batteries. One battery stopped working all together. I had bought duracell rechargables years ago that worked for years with no problem Now I can't find those but went to a regular battery store and found some that work ok.

They won't last as long as brand new premium batteries, but they seem to last a fairly long time from what I've experienced

Hello, El Jefe, These batteries last a long time in my Rosewill 3 "D" Cell, Cree-LED Flashlight. I don't use the light all the time, but it is very bright, and the charge lasts for months. I use an Ansmann energy16 charger. I have used a pair of them in the ignition part of our kerosene heater, and they too, have lasted a long time. I have never recharged them since they begin lighting up our heater. I really like these batteries.

A long while. I used them in a baby swing and only charged once between birth and 4 months with moderate swing use.

I bought 13. no issues yet. Check w/ company. I hope they last longer than yours.

It depends on how much you may use them will in motion. I walked with mine and they only lasted a few months before something either in the cable or the jack had a circuit problem. Great sound though.

I've had them HOLD there charge for 4 months of non use!up to 2 months of off and on useand for at the irish fest shooting and video taping 2 - 4 hours depending on how hard I'm goingThey do hold up well I cannot complain!Those batteries that only cost a few dollares and ya I've tried them!NO.....don't hold the charge for long and don't last that long either.I've had the cheapies go in 2 - 3 years you know freshly charged and Dead in 30 min.

to my knowledge they are good for a couple of years. they use next to no power and the ultrasonic noise they make is steady as long as the light (red flashing) is blinking. sometimes it may take a little while to convince your pests that they had best leave if they didn't want to go crazy listening to an sound only they can hear. i was amazed to see that these units did such a good job at driving off ants. we have them by the millions out here but never anywhaere close to one of these repellers. hope that answred your question.

We've had the phones for about 2 years now and haven't had problems related to the batteries. Seems like they last quite a while when talking for extended amounts of time on the phone. I've never had one quit while using them.

My experience has been pretty good with them overall. They seem to charge a "near" dead, (maybe less than 20%), i-phone about 1 1/2 times before they themselves need to be recharged.

Just to see if they work, try using them individually and see what happens. The only concern I'd have is foreign material getting inside the jack holes and messing up the connections or that the prongs on the outside are perfectly intact. If they work for an entire day, you're in business I'd say; otherwise, these are not very expensive to purchase. Good Luck!

Should work well, we use them to call back numbers for BINGO night in a large clubhouse. The charger is a handy place to store the mics, on top of the receiver unit and will keep the batteries ready to use. We use them once per week for six months of the year, and for 2 years. You might be able to buy a better set, but for the money, I don't think you can beat this set.

Definitely if they work right. We had a set before, and it worked beautiful, this time the volume has to be on 0-10 at least before it works. It has some static too. I think it is defective.

It all depends on how long you are utilizing them. I've only had them for a little over 1 month and they are working perfectly.

I've been running five for six plus months 24/7. No problems. Just keep them plugged in and they go.

Haven't had to replace them yet. Don't really know... The doorbell isn't used at all honestly. I doubt your going to kill it by using it, most likely it will crap out due to age.

I'm very satisfied with mine, I use them on a high drain device and it last a long time. A smoke detector should be a low drain service . Make sure you are charging then properly, my charger is over 10 yrs old and it takes many hours to re these but it does the job. Maybe you have a bad battery, or charger . Try also and see if they work on some other device.

That is precisely why I bought these batteries. They work very well, just make sure your smoke detector has a low battery alarm. The smoke detector in my basement started beeping after 4 months. the smoke detector in my living room started beeping (alerting me of a low battery charge) after 8-10 months. The batteries work great, but you have to make sure you have a way to testing the alarm every month or so. I test my alarm every end of the month on the weekend. That way I do not forget. These batteries have saved me some pretty penny so far. I hope my comments help you. tks vm BG
