how long will it run on 12 volts before the batt is dead

That depends on your house battery. If you have a 250 amp hour (Ah) battery, it is safe to go down not more than half (125 Ah). If the unit pulls 2.8 amps as it says in another answer, then 125 Ah ÷ 2.8 amps = 44.6 hours if it runs continuously and the converter isn't charging the battery.

Totally depends on two things: 1- Battery condition and other concurrent system uses 2- Ambient temperature then system is operating in. Consult your local battery dealer for some suggestions

on a really cold night ( under 20 degrees) it didn't make it til morning but on an average cold night ( about freezing) it made it until about 10 am

On a 12v car battery. While the vehicle is running, it should be 13.5-14.4V and while off, should be 12-12.5V

From what I can tell so far, when running continuous on high, the battery only last around an hour. But that probably isnt real accurate. My uses are on and off a lot. I dont usually run it for more than a few minutes at a time. I do know that this light does get hot to the touch when its been on for an extended period of time.

It requires 12volts DC. Doesn't matter what size the battery is. It's the voltage that counts.

depends on what kind of battery you get and how long you let it run without turning it off.

It will run on as little as 14watts at 12v. Anything less and it flips off and on.

power draw is 4 amps @ 12 volts. So if you have an 80 amp-hr battery you'll get 20 hours.

Depends I have about 3 to 4 hours on batt live at one time, it can be up two 6-7 if you are not using a lot of apps! Some people say 12 hours(hard to believe though.)

Mine runs a minimum of 30 minutes on a full charge. I've never run it out so I'm not sure how long it might last.

Rajesh, The run time depends on the size of your battery not the inverter. Joe

The only right answer to your question is, "it depends", because it depends on how much current you need to provide and for how long @ 120V AC. Since you are running a 12VDC input and a 120VAC ouput, you need about 10 times the current on the 12v side as you want out of the 120V side. Additionally, you need to have an understanding of Amp Hours capacity of the battery(s) used to provide the power to understand how long it(they) can provide the power needed.

Your in luck as I happen to work for Stanley Black and Decker. If you started at 12.8VDC you already had a partial charge. 6 hours to top off the battery is a reasonable expectation. For a fully discharged unit (~12.2V) charging a minimum of 12 hours is recommended. This unit uses polymer lithium cells that dump their energy extrememly fast. Its the only reason this thing works at all. It is meant to assist a weak battery not jump a dead one!

There are two 8.5AH @ 12V batteries, so to Dan's comment it would run for 1 hour and 20 minutes.

at 12 volts, the 10 watt light will draw just over 0.8 amps. The battery is rated at 5 amp-hours (5 amps for 1 hour, 1 amp for 5 hours, etc). So, under ideal conditions you will get just about 6 hours. Add in life's little inefficiencies and an assumption of 5 hours would be reasonable, depending on your exact configuration. Good luck.

It comes with a 7.4v bat. (2 1500ma cells in series) which can be upgraded to 2ea 1875 ma cells, this gives you about 8-10 min as opposed 6-8 min. on the 1500ma cells.

It would completely depend on what you are running I have not ran it down yet but you never really want to run a battery with high amp draw down under 40% with. I would guess a dc refg 3 days. You take the total amp hours times 12 gives you the watt hours on the battery. I haven't done it yet.

No. The unit works on 120 Volts Ac. If you want to run it off 12 Volt DC , you would need to purchase a DC to AC Inverter that converts 12 Volt DC ( from a battery) to 120 Volts AC. There are much cheaper ways to do this.. Just look for color LEDs that operate on 12 Volt DC... Hope this information Helps.
