How long will it continuously operate with batteries?

I am unsure of how look it runs continuously as I only use it for just a couple of minutes each day.

Greetings. Theoretically speaking, the batteries can last 100-120 hours. But it will also be affected by the battery type and usage. Thanks for your question.

Only when any key is touched, it runs on batteries so wouldn't last long if stayed on continuously.

We usually don't use ours for more than 90 minutes of continuous use. They could probably hit 2 1/2 hours with a decent battery, but it might be a stretch. I don't know if you need them to run continuously for the whole time, but we try to conserve power by turning them off when not actively in use. We're running them on Energizer rechargables.

Depends on your usage, it will last me several days but if I use it continuously between 6-8 hours

You would need to purchase the AC adapter (used in place of a battery pack) to run it continuously for that long.

I am unable to respond to this question, all I can comment about is that it charges up and then we can use it continually for several hours or days depending upon how long we keep it on.

I have had about 10 hours of continuous use on the device with the backlight on. It is a great unit, but carry spare batteries because you go from low battery to no battery quickly.

If you leave it on constantly then probably only 1 day it's a tiny battery. but if you only use it a couple hours a day it will last.

It's supposed to be 30 hours on 2 AAA batteries. If you leave it on, it will be dead the next day.

9 to 10 hours depending on setting and batteries used. I usually get at least 9 hours using rechargeable batteries.

Depends on what device it's for. In my Sony cam corder a couple of hours continuous use.

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

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.

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

I haven't gotten that far along, but I'm estimating at least six months. The light only stays on about 15 seconds so it can go longer. I used alkaline 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.
