How long do they last if left in the low or middle setting?

I use mine in the automatic low spray mode. This is 1 spray per 30 minutes. One can of AirWici spray in my AirWick dispenser last approximately 2+ months.

don't know. When I buy them they are usually good for 6 to 12 months or longer.

Probably an hour or two... But it really depends how long the string of LED are... I can't really say for sure... They're not that costly so buy 'em and try 'em to see... If you have a dimmer they will last longer.

It, of course, depends on whether the average setting is 'high" or "low".For me, it has been about 15 to 20 hours on the "almost always on high" setting.

They go off after like 10mins if u don't use em. U can turn the knob to off and on again or wait bout 10secs after playing something.. They said they got it cuz of the European regulations and it saves electricity

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.

Personally, I find them not all that bad. You have to wait for them to dissipate, though. By wait, I mean read the directions and wait THAT long. 35 minutes is probably best for most water. They don't seem to expire..my stack is still good after 5 years, but use 'em enough so that they're at least somewhat fresh, just to be safe.

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 will depend on how many hours you wear them but for me I get about a week to 10 days before they are dead.

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.

Indefinitely as long as you store them in a safe place. You should keep them some place where they will not be exposetto temps above 80 degrees.

In my usage I find you can keep using them probably 6 months or longer and I only use on one area at a time. Hope this helps you!!

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

It depends on the temperature that you store them at. regular room temp they are good for between 5-6 years. in the fridge they are good for 7 years. In the hot desert sun they are good for a year or less.

Mine lasted about 3 - 4 hours. However, I used them in my ski boots not regular boots, but I would imagine timing similar. However, I kept mine on low setting. These work OK.

How long they will last will depend upon several factors. How are you using them? How much power is your hearing aid drawing? (My right hearing aid is turned up higher than my left and tends to be the first to lose power). Are you using your hearing aids with blue tooth devices. When I'm using blue tooth devices a lot they can last as little as 3 days. Normal use 5-7 days. Also, I've noticed that all my batteries lose power a lot faster at high altitudes.

MIne are lasting quite a long time. Sseveral years and on for as much as 12 hrs per day.
