To determine how long an 8 Ah (amp-hour) battery will run a 4-watt pump, you first convert the pump's wattage to amps. Since power (watts) is equal to voltage (volts) multiplied by current (amps), and assuming a common voltage of 12 volts, the pump draws about 0.33 amps (4W / 12V). Therefore, an 8 Ah battery can run the pump for approximately 24 hours (8 Ah / 0.33 A ≈ 24 hours) under ideal conditions, not accounting for efficiency losses or battery discharge characteristics.
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.
To calculate how long a 100 Watt light can run on a 40 Ah battery, first convert the battery's amp-hours to watt-hours. A 40 Ah battery at 12 volts provides 480 watt-hours (40 Ah × 12 V = 480 Wh). Dividing the total watt-hours by the power of the light gives you 4.8 hours (480 Wh ÷ 100 W = 4.8 hours). However, this is an ideal calculation; actual runtime may be less due to inefficiencies and battery discharge characteristics.
No
The runtime of a 3000-watt inverter on a 12-volt battery depends on the capacity of the battery, measured in amp-hours (Ah). To calculate, first convert watts to amps using the formula: Amps = Watts / Volts. For a 3000-watt inverter at 12 volts, it draws 250 amps. If you have a 100 Ah battery, for example, it would run for about 0.4 hours (24 minutes) under ideal conditions, not accounting for efficiency losses or the battery's discharge limits.
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).

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.
Yes, a 12V 30 amp pump can run on a 12V battery, provided the battery has sufficient capacity to handle the pump's current draw. For optimal performance, ensure the battery can supply at least 30 amps continuously, and consider the pump's duty cycle to avoid draining the battery too quickly. Additionally, using appropriate wiring and fuses is essential for safety and efficiency.
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.
