How long the batteries last?

Depends on quality of batteries. I change the batteries every 90 days so I don't have to worry about it not opening.

Hi, are you asking how long the batteries last before they need to be recharged, or how long the batteries last before they are no longer rechargeable?

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

The rechargeable batteries last about 8 hours of continuous play. They are great for travel. Regular AA batteries might last 3-4 hrs of continuous play.

I can't remember how the batteries are that came with them. I have some of these that are almost three years old and I don't think I've changed them more than twice. I have a few that are almost two years old now and one of them just barely started cherping a month ago. I'd say the battery lasts over a year at least. They last long enough that I haven't given it much thought.

Quite a while. I have owned this for well over a year now, and I have only replaced the batteries once.

I have four of these, all installed since 9/2013. One of the batteries died after about 6 months, which kinda worried me, but the other three are still on the original batteries and still sound loudly when tested. So, 6 months to at least 17 months. These are nice little units, worth a few extra bucks for the small form factor.

It' hard to say but I have had them last 24 hours on standby. With use and time as with all batteries it seems they develop memory and lose their capability to maintain a charge over a long period of time. I carry two batteries with me and switch them. From the beginning of my day until about 4 o'clock I usually have to change batteries or put it on charge.

Sorry! I have no idea. I haven't had mine long enough to replace the batteries.

About 6 - 8 hours if you run the battery all the way down. Which I dont recommend because your batteries wont last very long.

About 3 hrs I think , good idea to have 2 batteries , it's a great little machine, I love mine!

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

About a good 6 hours maybe 8...I bought them as a Christmas gift for my two kids and to be honest I don't allow them on longer than an hour but my husband used it for 6 hours straight. Pretty good product I honestly can't complain.

I never run my batteries completely low so I do not know what the time would be from that point. I put about 3-5 hours of listening on them and the they are fully charged in approximately two hours.

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.

Guess I cant really answer that question. I put 6 D rechargables in it and have several fishing trips in with and it still has'nt used up the batteries, so its a long time. I would say I have over 24 hours of use on them and still going strong.
