how long do the batteries last?

Long time so far. I am sure it depends on how often you open and close the valve. Standby mine have lasted 6 mo. so far.

I have only used this one for about a month so I don't know. However, the last model I had lasted about two years. This is a GREAT product, very reliable.

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

4 to 5 hours I believe... depends on what your doing with them, constant music shorter battery life...

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.

These are not designed for continuous lighting, but for intermittent and for a couple hours at a time. If left on continuously, the batteries will last around 25 to 30 hours. These had been considered for a commercial display case but were turned down due to having to change the batteries every 3 days.

I can't give you exact hours but I can tell you that my sons use their players at campouts for many hours and I have never seen them go off. I have never used mine for an extended time on battery.

They last about a year. You can buy upgrades for it ( more run time). Batteries aren't covered. They are expected to be replaced.

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.

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.

Not long, had to buy an extra 3 pack of batteries to keep on hand. Never leave home without an extra one.

A very long time. I would say somewhere around 30 hours. The battery lasts forever though.

the battery life lasts approx 4-8 hours...sometimes longer if not used continuously.

I haven't exactly timed it and as one who has multiple batteries, I don't may that close attention and I don't run them all the way down...but I'd say about 30 mins on average.

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.

Not long. about 15 mins. of run time. I bought a second battery so i could easily swap them out and keep going.

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.
