Best Answer

First the amperage of the 1500 watt device has to be established. I = W/E. Amps = Watts /Volts = 1500/24 = 62.5 amps. To answer this question the amp/hour rating of the 24 volt battery has to be stated. This is the capacity rating of the battery. Take that rating and divide it by 62.5 amps will give you the amount of hours that the battery will take before it drains and needs to be recharged.

How many amps on a 1500 mah battery?

1.5 Amperes, or Amps.


How many kilowatt hours would be used if 1500 watt used for 10 minutes?

1500 watts = 1.5 kilowatts 10 minutes = 1/6 hours. So 1500 watts for 10 minutes = 1.5/6 = 0.25 kilowatt hours.


How many hours will 3600 watts last on a 637 amp battery?

7684973343487239485 hours.


How many hours a 850amps battery can run a 2000 watts motor?

It depends on the battery's voltage. Such a battery's capacity is given in ampere-hours, not amperes. An 850 amp-hour 12 volt battery can theoretically operate a 12 volt motor for about 12 minutes but in practice it's probably, maybe a lot less, since the motor will probably stop as the battery nears its depletion.


How many 9 watt bulbs can an 14 amperes 12 volt battery support?

Batteries are normally specified in ampere hours. A 12 v battery could be specified as 14 A-h or 14 ampere-hours, which means 14 amps for 1 hour, or 1.4 amps for 10 hours. In other words it produces less current for a longer time. A 9 watt bulb takes ¾ amp in theory, so it should last 14/¾ hours on that battery, that is 14 x 4 / 3 hours, 18 hours. Or two of the same bulbs for 9 hours, etc.
