To answer this question the amperage draw of the motor must be given. This amperage is then divided into the amp hour capacity of the battery to find the endurance time of the motor.
Yes - you can run a 1200 watt motor on a car battery - until the energy of the battery is exhausted.
No
To answer this question the voltage of the pump must be stated.
only if u use a battery to boost power ,
you need to get a lot of horses
It stands for watt-hour. In relationship to batteries, it measures how many watts in an hour a battery can sustain. A 63 watt-hour battery will supply 63 watts for 1 hour, or 6.3 watts for 10 hours or 31.5 watts for 2 hours, etc. It is extremely difficult to determine, from this number, how long your equipment (say, a laptop) will run using a 63 hour battery. The thing for which this number is most useful is battery comparison. A 20 WHr battery will last twice as long as a 10 WHr battery and half as long as a 40 WHr battery and so on.
A watt is a measure of power. It is volts multiplied by amperes, or just volt-amps to lots of electrical types. The amount of power is very easy to measure, but it can be used quickly or slowly, depending on the device "sucking up the power" from the source. A watt can last for a long, long time (as in a watch battery), or can be gone in a moment (as it would be when the microwave oven is turned on).
I have no idea what a normal household battery is. Generally you would have to match the current and voltage of the car battery and then you have the issue of how long the battery can sustain the current, or ampere hours.
It depends on the source of DC that is powering the inverter. Since the inverter is 2000 watts, that just means it will handle your 1500 watt application. At 120 VAC you are drawing a little over 12 Amps. If this is an inverter plugged into a car it will run until the battery runs down, whose time will be lengthened if you keep the car running. Your battery will have an Ampere per Hour rating. If for example you had a 50 AHr battery it could supply 50 Amps for an Hour so your heater would run for about 4 hours.
An ampere-hour rating is a relatavistic indication of how long a battery can supply a specific current.It is not possible to determine the run time when you only gave watts, but watts are volts times amps, and you did not supply the volts.
It means you can run whatever off the battery as long as power x time = 5. Ten watts for 0.5 hours. Five watts for 1 hour or 2.5 watts for 2 hours.
