How many hours of use on one set of batteries before they need replacing?

I use my lamp on and off for a week or two before changing batteries. If used steadily they would last somewhere from 6 to 10 hours I'm guessing before changing batteries but I'm using rechargeables. They dim steadily when the batteries loose charge. It's the best clamp lamp I've ever had and withstands heavy use. Very sturdy.

The expected life span of these batteries is approx. 1 year give or take a few months. My last set lasted 2 years

You should be able to get about 15 hours of use at least for each battery. Also, for frequent users, we recommend switching over to a rechargeable battery system. You can buy one on Amazon. JUST DON'T USE THE REGULAR C123 BATTERIIES IN THE RECHARGER BUT INSTEAD USE THE RECHARGABLE BATTERIES IT COMES WITH!!!

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.

I believe the description says about 100 hours per battery pair... but I havent used it that long yet...

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

They should work just fine and give you about an hour of working time before needing to be replaced with a freshly charged set.

Don't know, I haven't had to replace them. But it's my understanding they last or thousands of hours.

Should take somewhere around a little under 80 minutes on a battery that hasn't been abused too much.

Around 40 hours is all I would use it. You should be able to tell when to replace. I keep mine in the bag and sealed when not in use.

From my experience I wouldn't attempt to go over an hour. I had three batteries charged and ready at all times. When one would get low I would change it and put the used one on the charger. If you are shooting continuously go AC if you can't use AC keep an eye on your battery level. I hope this is helpful.

Using standard batteries, you can expect approximately two hours of battery life

Leon, I've had mine go for 3 full days with intermittent use maybe 3 to 4 hours a day, before I've become afraid they are going to be dead and charged them.

I've got about 10 hours of footage on my first set of batteries. It uses A A's so carry an extra set to be safe.

You can still buy brand new replacement batteries for these for about $75. On a new battery, this machine will run 3-4 hours on a single charge. When the battery gets old, as in any laptop, it won't hold for more than a few minutes. But that has nothing to do with this particular model of computer. That is true of any computer and any rechargeable battery system. Depending on which one you get, you might get 30 minutes or 3 hours of batter life. It's impossible to know. Ask the seller. If the batter is less than a year old, you will get very good battery life out of it ... at least 2 hours.

Easy. I recently replaced batteries on two units after 2 years of use (10-20x cycles per day per unit). The 9V batteries are under the inside plate. It took me about 2 minutes and required a common Phillips head screwdriver. One unit had a completely discharged battery. I replaced the battery in unit #2 ... "just because". Both units retained all of the codes; although re-coding is easy (if you have the instructions ;^)

If you listen to music at a moderate level, you should get 8 to 10 hours out of a single alkaline battery. At least, that's the running time I get out of them. (dollar store alkaline batteries)
