How long will they operate on a single charge?

I could never get them to operate at allconnection and installation instructions were not included. My advice - don't buy them.

I've used mine for several hours. I havent timed it but I've been very happy with my purchase. They will also provide a light beep to let you know before they die to plug them in.

Charge them over night and you will be fine.... Now how long do they last is another question haha

About 6 hours but I bought 8 of them and one stopped accepting a charge after less than five cycles. It was only four months old but the Amazon seller would not replace the faulty one

Since they are rechargeable, I have no idea how many times you can charge them. However, we've never had them discharge fully but only use them a maximum of 3-4 hours at a time with no problems.

Cannot say for certain. We charged ours overnight & they were ready the next morning.

I re charge between each round, not sure how long it would go without charging, my guess would be six hours maximum.

I would say I get a good 10-15 hours of runtime on a single charge, and standby time is also pretty good, charges up pretty fast also!

It needs charging from mains via an adapter - will run for quite while on one charge.

I have not actually timed it do be certain, but I walk with them and figure they stay charged for a minimum of 2 hours. Normally me walks are 30 minutes a day and I only normally charge them once a week.

I would estimate about 45-60 minutes. The number of charges obviously depends on how you use your phone but I can get up to two full charges.

Hello. Based on usage a full charge should last between a couple weeks of non-usage to a few days of extensive use. Thank you

I have found that a full charge will last for 1/2 to 3/4 of an hour if used constantly for the whole time. Also depends on how fast you run it.

It takes quite a number of hours. I'm not sure exactly how much, because I plug them in overnight. By morning, they're charged. I'm guessing about 6 hours.

I would say it depends how often they are actively running. In my experience, using them in the same product as a disposable, I get 24 hours per charge or 3-4 times longer than that with a disposable. If you know how long a disposable lasts in your sensor, you could make a guess that this would last for your purposes.

It holds a charge for quite a while. We tend to get a solid 6-8 hours of use out of a single charge.

A hour or two. Very worthwhile. The price is cheap enough to have sufficient power to do the job. Don't plan on a quick recharge. Just have enough for the job. If the job is very long. You can recharge while the other batteries are working.

I cannot answer that fully. I have not left them on long enough for them to lose charge. I have the manual at home. So I would guestimate 15 hrs? Maybe more, maybe less. Best bet is the manual, what it says, but if you don'g actively correct them for a long period I would think it would hold charge a little longer
