How many amps per hour does this draw? Will it run all night if I run it off my car battery or a 100 amp house marine battery?

Hi, The average running time is 3 amps per hour. I do not know if it will run all night on your car battery because I do not know the amp hours and condition of it, however your marine battery would run it for approximately 30 hours before it would have to be recharged. Joe

1.5A each. Depends on the battery. If one of these is installed in a car, most car batteries are only 25A/hr so it will run for 16 hours if you battery is fully charged. I have had one mounted on a box and ran it with a deep cycle marine battery for 6 hours with no problems. 2 lights would obviously cut the run time in half.

About 2-3 tenths of an amp per ft, with the full 16 ft, it runs about 4 amps, even under DC power source like a deep cycle marine battery, my strip ran for a little over 3 months strait before I needed to recharge

I believe it draws around 6 amps/hr. If you know (or can calculate) the total amps in your battery, you can divide it out to get approximate hours of use. In my camper using a deep cycle battery I can easily use on medium for two nights without a problem.

I used a standard car battrery and it ran a radio 2 40 watt lamps for days before needing a charge. Make sure you dont get poitive and negitive mixed up. It killed my inverter dead.

This is a 12V battery, but for running even a small winch that still pulls ~40 amps I'd go for a bigger battery. This one is rated for 18 amp-hour (hinting it'll supply 18 amps for 1 hour, or 9 amps for 2 hours, etc) and I don't think it's a good idea to pull more than that 18 amp rating for more than a few seconds (like to crank a car).

I guess it all depends on the battery and how often the pump will turn on. Get a GOOD Deep cycle marine battery and it will go for hours. I got it for peace of mind just in case the power goes out. Hasn't run yet, but neither did my AC sump.

It's only 100 watts so I just use it for a 12volt marine deep cycle battery. It comes with Anderson PowerPole connectors and a set with Alligator clips. It will recharge a vehicles battery as well.

The unit only pulls 100 amps when you in essence create a short circuit across the battery terminals through a big power resistor. You should not hold the short for more than 10 seconds. If the needle stays in the green during that period you have a good Automotive battery which is often called upon during an engine start to pull 300 to 450 amps. I have found it to show useful information on several types of 12v batteries, but I am not sure that it was designed for a deep cycle battery. It did find deep cycle batteries that dropped into the yellow from the green, and they were older batteries. I would try to contact the manufacturer for more engineering data. Hope this helps. Dick

5 or 6 hours for a 100 Amphour battery or faster if you use the 120 AC to run a 15 - 20 amp battery charger which I prefer

I use a 12 volt car battery. It runs all afternoon on it. It would probably run even longer on a deep cycle marine battery.

This motor is rated at 0.360 Kw. This converted to amps is ~ 30 amps at full power. On top of the control head, there is a basic chart on what to expect based on how you use it and the size of the battery you use. I'm using a battery rated at 180 @ 25 amps. I could run this for 3 hours on 4.

I believe it all depends on the draw of you CPAP as this battery is only 7 amp - so 7 hours of use at 1amp and you should run out of juice. I bought mine for my fishfinder, but take a look at the link below as it is what I found on Electrical draw from A CPAP and it appears as if it draws more than people think versus how many functions you have it doing off of the battery. http://www.apneaboard.com/forums/Thread-Equipment-How-many-DC-Amps-does-my-CPAP-REALLY-draw

I believe it draws around 10 amps, I myself had not had any fuses blown, most of the time I hook up directly to battery although I have had it running off my trailer light connector on back bumper with no problems.

Hi Elizabeth. I'm using an Exide MC-31 MEGACYCLE AGM-200 (AGM) Marine Battery. Fully charged, this battery can keep the refer at 38 degrees for several days (depending on outside temp). I would not recommend running this off of a car battery/alternator.

I'm not sure. Mine is running a car stereo. It can run for sereval hours. I just don't know how many amps I'm pulling from the battery.

You can run a pump, or anything else with this battery. The time it will run is dependent on the current the pump draws. This battery would run a pump that draws 2.5 amps for up to 2 hours.Check the current draw of your pump. It would easily run a pump drawing 5 amps for 1/2 to 1 hr.
