Cannot be determined with the information given.
If you are asking about on a single charge, the load current must be known.
If you are asking about total life of the battery before it cannot hold charge, there are so many variables that any answer is an estimate that may be off by orders of magnitude.
If you draw 280mA continuously, the battery will last 1 hour. 140mA continuous use will last 2 hours and so on.
It depends on how much drain is placed on the battery !
To answer this question the amp/hours of the battery must be stated.
Up to 2 or 3 hours
lun times
it doesnt matter what type of computer you have, it depends on how long the battery in your computer lasts. there r many different types of batterys. some last a couple hours, and some last up to 6 hours.
the length of your battery time will depend on the length of time you are using your camera, if it is on constantly then it will only last several hours but if turned off it will last for many days
it depends on its usage.usually it works 350 hours
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.
The time a good battery will last generally depends on the rate of discharge. There is a fairly handy way to find out if you have a bit more information. The DigiKey battery life calculator can easily be found on the web.
A 5600mAh battery can last anywhere from a few minutes to several hours depending on the device it is used in. Typically most cell phones can last for many days with limited usage.
Its battery life is 3 to 4 hours.
