Sorry, I have no idea. The unit I received as a gift never worked at all. I really prefer one that plugs into an outlet and has a battery for backup.

Always change the battery every year. ...cheap insurance. Many recommend even New Year.

Stop buying crap batteries. I have one and they have lasted over 5 years. I change them yearly now that I started to use my fireplace.

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.

It lasts quite a while. I don't use mine much but I have only put one set of batteries in.

They are water powered, no batteries so I guess they last as long as the LEDs. Probably a really long time given most LEDs last over 40,000hrs.

I use the light for 1 to 2 hers at a time during orchestra rehearsals 1 night per week and church services on Sunday mornings. 1 set of batteries has lasted for about 3 months and I just had to replace them. I think the info that came with the light said they should last about 10 hours of continuous use.

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.

I've kept them on both my dogs for 12 hours and they still work well. I always plug them in at night so I'm not sure how long they last. I know that even when they are immersed in water, my dogs swim, they still hold the charge.

Not long at all. I had to stop using mine. When you put batteries in you get about 8-9 good hours, then light begins to dim. It is worthless!!

Tough to answer. Length of time in use and volume will impact batteries. I often use it 4 hours a day and they last about two weeks.

I have had it for a few months. Use it a few hours a week. Haven't had to replace the batteries yet.

I am not sure about a whole 16 hours; I haven't tried to make them run that long. I've seen them go for as long as 8 hours and they weren't fading, we just turned them off after that. The battery doesn't look replaceable to me; it's a closed clear plastic case. The strands pull out and the plastic barrette case won't put up with a lot of abuse.

Hi there....I can't say exactly how long the batteries last, but I do know that we went to Haiti and ran two of them ALL night while we slept for one week, and never changed the batteries. Hope that helps.

I'm still on my first set of batteries I put in it (2 AAs) and I'm amazed they've lasted this long. I've been using it off-and-on both day and night. The other night I fell asleep with it on and expected the batteries to be dead in the morning. They're still going! I turn the radio off when commercials come on so I'm sure that helps, but still, I've been pleased with battery life for this radio.

They last pretty long. Make sure you use quality batteries, like Duracell or Energizer. Don't forget to turn them off when not in use. I don't want to attempt to guesstimate how many hours, but we really don't have to change them often. If they start making funny noises, time to change batteries.

Depends on use. We used ours for 2 nights(all night long) before we replaced batteries. We used cheap batteries

They last very long, I bought this in July 2013, and I just recharged the D batteries at the beginning of December 2013. The batteries weren't even drained, I just wanted to make sure it wouldn't die before I went on vacation.
