Any information on how often it runs? A 4.5A draw on 12V can be a big range of total draw depending on if this runs for two or eighteen hours per day.

Thats going to depend on where you tun it. Keeping it out of sunlight & indoors well ventated in a camp for example makes a difference plus temp settings. For example I ran it zones set about 20/35 degrees for about 3 weeks in late September to eary Oct. it would cycle maybe 10 - 15 minutes out of an hour depending on how often your opening compartments. On a 1/3 kilowatt solar system & 400 ah battery bank I had no problem and reserve power.

In cold temps when lids aren't opened often it may turn on for a few minutes once or twice in a 24hr period (55 degree garage). In hot 90 degree weather it will turn on for a few minutes about every 15 minutes. In full sun, or if opening lids often, it will run nonstop.

In practice it's more like 6 amps, but at room temperature mine runs less than 20% of the time. Of course the lower the temperature it's set at and/or the higher the ambient temperature is the more it runs. I fear there is no one size fits all scenarios answer to this question. Also in practice, I had no trouble running two of these in the upper 90's (daytime, of course) on about 800 watts of solar panels.

Once the interior temperature reaches your desired setting that you provide to the digital read out, and depending on the climate that you are located at,and season as well, and as long as you are not opening and closing the refer doors all the time, the compressor will shut off, thus, not drawing a constant 4+amps, or what we call full load. When the interior temp starts to rise above a 2 degree threshold, is when and only when the compressor will begin with the heavy amperage draw.

Doesn't matter. 12V 4AH means the battery is 12 volts and has a capacity of 4 amp hours. The 12V 5AH has the same output as the 12V 4AH, but a 20% longer run time as stated in the description. As long as the voltage is the same, amp hours can vary. I ordered a CA1240, received a CA1250 - no problem. They are the same size. My last battery was a smaller 12V 1.2AH and worked fine for 7 years.

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).

Those little transformers are rated for 12volts at 500ma. I'm running four units on one transformer for the past two years, sixteen hours a day with no problem. Hardly warm to the touch. Five units shouldn't be a problem.

a 20# tank on high has lasted me 6 hours if not on high roughly 11. They say 14 on low but I have never run mine just on low.

We never ran ours more than 10 to 15 hours a day, when it was warmer and drier and never at night or during the rain. I inserted it in a square frame of wood with the appropriate size hole and inserted it to blow in or draw out, and ran it all last summer. We do not use it in the winter as we close off all the vent openings. I do not know your circumstances for running it, but maybe it would be a different story if the application was "continuous" as opposed to "sporadic". For me: So Far So Good.

4 AA 2500mAh batteries in 5 hours so 4 x2000 in 4 hours or 500 ma per hour. Won't make any difference what your charging source is, it only draws 500 ma

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.

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.

that all depends on what you are powering. i use mine for just powering a cash register and night lights, and it will last all day. if you use it for like a coffee maker it will only last a couple of hours. it all depends on what the amperage of the item that you want to power.

It really depends on the amount of current draw, but I can tell you that generally you are going to get about 10-15 minutes of runtime from this unit on a standard computer. A gas generator is the only low cost option that will give you 3 days.

Batteries are rated in mAh or milliAmpHours. AA batteries are normally 1500 mAh. This means you can draw 1500mA for an hour or 1.5 Amps for an hour (just removing the milli by multiplying by 1000).If you are drawing 2Amps this would last for 1.5Ah/2A this leaves you with 1.5/2 hours or .75 hours or 45 minutes.

This has a fair chance of running those lights, but keep in mind this is a battery with a limited supply of power. The battery is rated as "26 amp-hour" hinting it'll give you 1 amp at 12V for 26 hours, or 2 amps for 13 hours, etc, so for it to last 10 hours means you can't use over ~2.5 amps. When running things off the inverter, the overall power used is about the same but the 12V gets changed into 120V and the amps get changed from 2.5 amps to 0.25. I just tried a string of 26 LEDs (with the 1-2 inch cone on each) that shows 0.04 amp draw, so I could only put 5-6 of those together if expecting 10 hours. You may need to check yours to be sure of what yours needs since they may be different (I used the "kill-a-watt" meter to measure mine that you may want to consider getting to see exactly what yours use).

Yes. 6800mAh is 6.8 Ampere-hours at 12V. It should therefore be able to run at 1.5 amperes for more than four hours. I wouldn't run it much higher than that, though. 1.5 Amps is a lot of current for that little battery. I routinely run a 3800mAh unit (=3.8 Ampere-hour) at 0.9 Amp for over four hours.

Not sure on watts, since that really doesn't matter on the 12 volt platform. I am not concerned with watts, only amp draw, as that is what the battery is supplying for. Normal 1141 BA-15 draws right around 1.6 amp hours versus these LED's which are drawing just over 250mA hours. Basically I can run one of these six hours on about the same amount of battery power as just one 1141 bulb! Or I could run six of these for one hour versus one 1141 for the same one hour on the same amp draw. Clear as mud right??

I've had mine for just about a year... I'm noticing just a bit of drain on the battery life. I'd say it's a strong 10-15 minutes. That's about all you should expect out of 6V. At less than half the price of a 12V I still recommend it. If they had one with a crevice attachment and at this price I'd buy stock.

It is definitely not 7,5 hours. 3 to 4 hours, I would guess. I used it more than 3 hours yesterday, but I think that you will not get 4 on that battery, even if power management is set to reduce maximum. After a year, I expect 3.Right now it says 1:56 (46%) remaining. Indicating +4 hours totally.Cheers
