To determine the hours a 3600-watt load will last on a 637 amp battery, you need to convert the wattage to amperes. You can do this by dividing the wattage by the voltage of the battery. Assuming a standard 12-volt battery, 3600 watts divided by 12 volts equals a current of 300 amps. Dividing the battery capacity (637 amp-hours) by the current (300 amps) gives you approximately 2.12 hours of runtime.
To calculate the duration a 12 volt battery will provide 100 watts of power, you can use the formula P = V x I, where P is the power (100 watts), V is the voltage (12 volts), and I is the current. Rearranging the formula to solve for current, we get I = P / V. Plugging in the values gives I = 100 watts / 12 volts = 8.33 amps. The battery's capacity, typically measured in ampere-hours (Ah), can then be used to determine how long the battery will last. If the battery capacity is say 50Ah, you can divide the capacity by the current to find how long the battery will last: 50Ah / 8.33A = approximately 6 hours.
To power a 100-watt light bulb with a 12-volt battery, you would need to divide the wattage by the voltage to find the current draw, which is 8.33 amps in this case. Then, depending on the capacity of the battery, you would need to calculate how many hours the bulb can be powered for.
Assuming 100% efficiency in the conversion process, the power output would be 7 hours at 12 volts, so the total watt-hours of energy stored in the battery would be 12 volts * 7 amp-hours = 84 watt-hours. With a load of 20 watts, the battery would last 84 watt-hours / 20 watts = 4.2 hours when converted to 120 volts AC.
To calculate the remaining time of your cardiac pacemaker in ampere-hours, you need to know the average current consumption of the pacemaker in amperes. If you have the voltage (2.75V) and the relationship that Volts = Watts/Amps, you also need to know the power consumption in watts to find the current in amperes. Once you have the current consumption in amperes, you can calculate the remaining time by dividing the capacity of the pacemaker's battery in ampere-hours by the current consumption.
An 8 Amp hr battery would last approximately 106.67 hours with a 75mA current draw. This is calculated by dividing the battery capacity (in Amp hours) by the current draw (in mA) and converting the result to hours.
To answer this question the amp/hours of the battery must be stated.
85/35=2.4286 hours.
Depends on the current draw of what you hook it up to. At a draw of 7 amps (80 watts) it'll last for one hour. At a draw of 1 amp(12 watts) it'll last for 7 hours, ASO.
arround 1 hour just joking around 7 hours at medium brightness and low volume.

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 panasonic triple a battery last about 4 hours nonstop.

If you draw 280mA continuously, the battery will last 1 hour. 140mA continuous use will last 2 hours and so on.
About eight hours
10 hours.
. The iPad can last 15 hours or more
