I really only used this on one camping trip so far. Lasted for the entire evening. I have not had to up hangs the batteries yet.

Generally lasts about 20-30 minutes of continuous use with fresh alkaline batteries. If you switch it off when not in use, you can get as much as 40 minutes out of it total.

I put fresh batteries in before a trip I took for 14 days & I ran it every night. The batteries are still good but I am taking an extra set of 4 with me on the next trip......just in case!

I've had them a month and have used them for hours at a time and they are still working. I didn't think they were gonna last this long to be honest. They take watch batteries in case you were wondering.

Approximately 8 and sometimes 10 hours if I leave them on and if I buy really good batteries. They are easy to turn off and on to save battery life and easy to change the batteries

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 have used my set for nearly a year with no problems. The batteries should last at least a couple of years if not 3 or 4+.

It depends on your settings. If you have motion activated and long record times it will be shorter. I get 12-18 months on a set. Also I buy the batteries in bulk and they are surprisingly cheap. Never buy them retail. They have very long storage life.

Depends on what kind of batteries you are using. I have two on my light. They seem to last about 2.5 to 3 hours before I need to change them out.

We've used ours for almost two months without a battery change. We use our remote for 30 minutes or more once a week, so we've got 4-5 hours on our first set of batteries. It stands to be said that we only use it for a remote and not as a laser pointer or timer.

The batteries will last approximately two years when in standby mode. If the alarm is sounding continuously, the batteries will last approximately five hours. With normal use the alarm will not constantly be in standby mode or sounding continuously. Therefore, the user can expect the batteries to last anywhere from 3-12 months depending on how often the alarm is activated.

I haven't timed them. I use it for about 10 or 15 minutes per day, and I have to change the batteries on average once a month.

I have this set, two chargers and 4 batteries. I can say I beat the crap out of these for the last 6 years doing home projects, subjected them to things I probably shouldn't have, and they're still going strong. "Heavy usage" is difficult to judge, but I'd say I'd could kill a battery in an hour with my heavy usage, maybe less if I really tried. I just leave a battery on the charger and swap them whenever I need to. I'll add that for my usage, battery life has never been an issue (but if I'm going up on the roof I do bring a spare battery). However, I wouldn't recommend them for a pro. I have this set, two chargers and 4 batteries.

On the higher setting, they probably lasted around 18-24 hours. On the lower setting, you could probably expect 24-36. We used them in Haiti and were pretty pleased with their performance. Ended up using half of the batteries that I expected to.

One set of batteries lasted about six months. Always carry a spare set. We scanned 1 to 5 pages every week or so.

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

I am going to say probably 4-5 hours on average if they get a good charge during the day. I now need to replace the battery in one of them, but I have had them for about 4 months. The others I have are still going strong.
