This light uses 3 AA batteries, and I don't know how long they last - I haven't changed mine yet. (I started using mine around Dec/Jan.) This is a task light - not a light I leave on constantly, although I do use it frequently. LED lights usually are easy on batteries, so I'm going to guess that the batteries will be good for some time to come. I still love this little light - super bright, lightweight - but not easy to tip over, directional and adjustable, and so convenient because you can use it almost anywhere and takes very little space. Hope this helps you!

It uses AA batteries. Not sure how long the batteries last. We purchased these for power outages and providing some extra light for close work. Bright light at first but the light dies fade as the batteries lose power.

Same size. Using them smoke alarms so I don't have to replace batteries every 6 months. Thinking we can go 4 years

I can't give you an exact time length ... However, I can tell you that the batteries in mine have lasted for 15 months with moderate use of the safe each month. The safe will alert me when the batteries are getting low and need to be replaced ... but as a rule - I replaced them in battery sensitive equipment every 18 months regardless - if not sooner (depending on use.) Hope this helps.

I can't give you a specific time these last, but I have had excellent performance out of them. I use them at night to light up my camper and I have been out as long as two weeks and they made the trip on a single set of batteries.

Battrey life is around 4-5 hours, I have Three "New" ones in the family. All are AT305T16. This is normal. We Love Them. We Payed Over $500.00 for 2 of them, Each. Looks like your refurb is as good as new. Amazon Price is the Best! Thanks Amazon!

I didn't do any scientific measurement. My opnion is therefore subjecive. It appears that these batteries do last. This key is to get them fresh. Batteries do lose power with time if you let them sit. Some lithium button batteries that I purchased on e-bay were two years old and lasted about a week in my guitar tuner, which is way too short. I blame it on the age of the batteries. Those 9 volt lithium batteries don't seem to have this issue. We'll see in a few years.

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.

I believe the candles with GOOD quality batteries like Duracells are rated to "burn" for 500 hours on the 2 batteries. I use the auto timer which turns them on for 5 hours then off....so you get about 100 days. They will flash on and off as the battery is getting to its last amount of energy. Lets you know to replace them.

Depends on the brand of batteries but I was energizer max and using it everyday they last a month or two

We still have not had to replace batteries yet. My wife played with just 4 cubes until we got a replacement for the cube that came out of the box with a dead battery. We got a replacement for the dead battery around 1 Jan, and she has been playing with all 5 cubes since. We are still using the original batteries, but I have no clue how many actual hours of playing time.Has anybody tried the inexpensive batteries that are available on Amazon yet? (See 4 Jan post above.)ww

They seem to last about as long as the Nikon ones. The nice thing is you can pull 1 battery out, and swap a fresh one in, so if you have 3 batteries, you can shoot to your hearts content while leaving one in a charger.

I beleive the less expensive one is not the extended life batt.....you want the extended life batt....the one that comes with the unit only runs it for a 2 to 2.5 hours....not long enough....;the extended will do 4 hrs. I usually take both with just in case...

I does last for a long time....I bought mine in Feb. and it is still going strong...normally they are supposed to last 50,000 hours and I am still counting.

Mine last at least 6 months, but a couple have lasted close to a year. It depends on the battery, weather, and how much traffic you have to trigger the alarm. The lithium 9 volt batteries do not work correctly because the voltage is too high and it causes lots of false alarms. Hope this helps.

The batteries for the lawmate PV900FHD should last approx. 2 hours I haven't run mine until it has died yet though.
