It depends on the voltage and current ratings of the battery. Most rechargeable batteries have these values printed on them. Lets say it is 1.25 V and it is 2000 mAh. This means it can provide, ideally, 1.25 and 2 amp for 1 hour (1.25 V and 1 amp for 2 hours). I think you got the idea. So it is 1.25*2=5 Watts.
To calculate the watt-hours of a 200Ah battery at 12V, you can use the formula: Watts = Volts × Amperes. Therefore, a 200Ah battery at 12V would provide 2400 watt-hours (Wh) of energy (200Ah × 12V = 2400Wh). This means the battery can theoretically supply 2400 watts for one hour, or proportionally less for a longer duration.
Volts * Amps = Watts 12 Volt * 2 amp = 24 Watts
Assuming 100% efficiency, a 36-volt battery charger would use 36 watts per hour to charge the battery fully. However, it's important to consider that chargers are not 100% efficient and may draw slightly more power from the wall.
To calculate the wattage produced by a 48-volt battery, you need to know the current (in amperes) it can supply. Once you have the current value, you can use the formula P = V x I, where P is power in watts, V is voltage in volts (48V in this case), and I is current in amperes. So, without knowing the current, we cannot determine the wattage produced by a 48-volt battery.
Normal clocks use little power, for example I have one that lasts 1 year with a single AAA battery.
You get actually energy (Watts) out of a battery, not calories (which is food energy).
Depends on the maximum current you can get out of the battery, and the maximum current whatever the battery is hooked up to can draw.If the max current drain of the load is less than the max of the battery, then you'll only get the lower value. If you'd hook the battery to a small LED light, you wouldn't be getting many watts at all. If you'd short the battery terminals with a nail or something you'd get a HUGE number of watts very briefly, until something broke.
A small one 100 watts, a large one 1000 watts or more.

There are one million (1,000,000) watts in a megawatt.
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.

There are 1000 milli-watts in one watt.
One million watts
2.4705 watts/hour
One horsepower is approximately equal to 745.7 watts.
It depends which one you have
