How long will it burn with regular Energizer batteries?

i went at least 3 years without changing the batteries. Normal use was 3-4 weekends per year of camping plus a power outage or two.

we don't use this in the "on" position for long periods of time to get your answer. however, we have used the light for an hour or so several times and it has worked well. we have not had any issues. i have not yet replaced the batteries since i purchased over one year ago.

You have to buy the energizer lithium batteries. They will last you about 15-20 hrs. Use for only one day of shooting, they dont hint at dying, they will stay at three bars and then go to zero in less than 5 mins at end of life

Not long at all. I had to stop using mine. When you put batteries in you get about 8-9 good hours, then light begins to dim. It is worthless!!

Basically I got very sparse directionsMyself. These type batteries should not be charged over 8 hours. Will possibly overheat. Recharge when they go dim. I never need to use full power as housing gets very hot. Do not leave light connected to battery as small led in switch will run down battery. Hope this helped. Lee R

You should really ask the company, but in my opinion,it is for a couple of hours. If you leave any household machine on for days, it will burn up. See other reviews on how these machines failed.

It depends on how long you intend to run the appliance. Frig. 3-4amps @ 120V = 420 watts. Divide by 12 = 35amps per hour. Typical large battery has 150 amp hour capacity but not at that rate and not fully discharging. Regular batteries are cheaper and you will only discharge to about 11.5 volts. That is why most residential system use line inverters and sell back to the utility. My starting point would be 10 if I was seriously wanting to benefit from a generator / battery backup on these appliances.. A couple of batteries could take all the charge a 100 watt panel could produce for days. Store it, use it or lose it because you can't afford your design intentions here.

I just use a regular Energizer or Duracell and it works fine. I get the batteries from work and one last a month or two using the light maybe a couple of times a week.

Max is only 30 minutes and it will get hot. Also will drain the batteries fast.

Depends on your usage. .. if you use 2 hours daily maybe can lasts for year or 2 ... but issue with battery more rechargeable batteries can use 2 hour continues but as you cant store for 2 days even every time you need use you need recharge batteries its painful for me... and normal batteries will cost you each time and not usage long on heating time. .. soo i use my normal solder more rather then this. .. but works ok all... but not worth to buy coz something you feel irritate to use its worthless... hope my answer will help you some.. thanks

Well I'm sure it depends on the brand of batteries. I used off brands from Menards and as most things from Menards its low quality so i got about 3 weeks out of the gun. I am not sure how much my kid used when i wasn't around so i cant give an estimated amount of hrs it will run

The short answer is "Yes". David Tullos says it will last 8 - 10 hours on full load (1500 watts) but I do not believe it will last any where near that long. The first link I have provided below computes the battery will last .66 hours at a continuous 1500 watt load and that makes sense to me. I have run a 2500 watt inverter on 1 of these 12 volt 100 amp hour batteries. The inverter must be a 12 volt inverter. The question is...how long will the battery last. That depends on the average (a refrigerator for example) or continuous wattage (maybe a 1500 watt heater running continuously) used by the electrical devices being powered. Of course the fridge doesn't run continuously so you have to take that into account. If you run a 1500 watt heater continuously off of this 100 amp hour battery you should be able to compute how long it will last. You also do not want to discharge the battery too much below 50%. There is a certain amount of research you need to do part of which involves using very thick gauge (probably at least 4 awg but maybe as large as 0 awg) cables from the inverter to the battery which your inverter documentation should tell you. The general rule of thumb for DC current is that for every 1 amp of AC current used by an appliance you will draw 10 amps of DC current from the battery. 10 amps of AC current will draw about 100 amps of DC current. Here are some links that might help. I do not know how reliable these are but they seem to be correct with my understanding of electricity and the research I've done. The first link seems to be the simplest to use by plugging in your own data. http://usasolarwind.com/Tools/BET.html http://powerstuff.co.za/battery-size-calculator/ http://www.bdbatteries.com/dcdcsolar.php I hope this helps.

Depends on how much you use it, and what type of battery you use. The bulbs being used take very little amounts of juice from the batteries so you should get many hours from the batteries.

I wear mine every time I am sawing, turning and sanding. Its like a habit now. I get anywhere from 7 to 8 hrs per fully charged battery. I have 2 battery's; one in the shield and the second one charged and ready t go. They are on the charger no longer than 12 hours (over night).

i use 15 minute energizer charger and batteries still holding strong 1 year later, I think trick is to use same charger from beginning... these are the best batteries I've ever had. They put other NIMH to shame..

I have run it for about 6 hrs before on a fully charged battery. Sometimes 7 depending on how often it is used. I keep a spare fully chargedbattery on hand just in case.

It depends on what brand of batteries you use. I use my fan on and off when I get hot flashes for 3 to 5 minutes at a time all day long. With Duracell batteries 2 batteries will last up to 5 days like this, although the cheap batteries that come with the fan only last a couple days. Also the fan will blow much better with the duracell or energizer batteries. You can really tell the difference. If you are purchasing for hot flashes I highly recommend this fan. However eventually the blades need to be repositioned ( squeezed together, no big deal ) or it wont blow as well, straight at you. I usually replace the fan with a new one every couple of months so stock up It depends on what brand of batteries you use.

not very long about an hr. on regular batteries / you need to really do rechargeable batteries then it would last longer . hope that answers your question
