How long do these batteries last?

These are rechargeable and I put them in the charger every night. They last about a year.

I replace them out of habit every 6-8 months. When new and fully charged they will run for a couple of days in normal use; when streaming from my BT player or TV they last through the day I'd say 8-12 hours. I have rexton cobalt 16 rechargeable, put them in charger at end of day, and they are great.

I usually get 1-2 days of use out of them depending on my volume settings. Definitely a full day's worth, though.

These batteries last about 12-14 hrs then need a recharge. Their life expectancy is approximately 9 mos give or take. Make sure your battery charger is the correct one for these types of Batteries.

Mine are still on the original batteries and I've used them through 3 dinner parties. They have run approximately 12 hours for me and there is still light. They are led lights so they pull very little off the batteries.

The person I bought these for has died; therefore I cannot really answer the question. I only know that I heard no complaints from him. If I am able to locate any of the batteries and find find out that information I will let you know. Get back to me in a few days.

I've had them a month and have used them for hours at a time and they are still working. I didn't think they were gonna last this long to be honest. They take watch batteries in case you were wondering.

Most batteries last 4-5 days depending on how many hours you have them on each day.

We have ordered those batteries several times and have had no problems. They seem to last 8-10 days.

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.

I don't leave them on all the time but at least 20 to 30 hrs prob more. They are a common size flat battery easy to replace and has like 3 settings of flashing and one solid. My batteries havent ran out yet.

I had fantastic luck with regular double A batteries as well. Generally, they would last for maybe about 8 hours of life, and I always got accurate battery life readouts, and was always able to replace them when they got low without any issues.

I've left them in for a reasonable period of time (life of batteries) with no ill effect, though it could possible shorten the battery life. I have no evidence, just a hunch.

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.

Depends on the brand of batteries but I was energizer max and using it everyday they last a month or two

Have only had mine a little over a year, and I don't use it daily. The batteries still seem as good as when new. They hold a charge even when I leave them unused for a week or two.

Hard to say because I only turn them on when I'm taking them out for potty time at our lake house. I can say that one of them got stuck on and I had to remove the battery to turn it off. If you look around online you can find batteries for these pretty cheap. Overall they are not super high quality but do pretty well.

It says on the box that the batteries last up to 55 hours. I would assume that is on the low setting. Other than that, I am not sure how long they would last on high. My daughter uses one of these for weekend camping trips and says they last a good while, but she has never paid attention to how long in hours.

Don't know for sure......Been using them off, and on now for four months, and haven't replaced batteries yet.
