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.

How many watts does my 12 volt 2 amp battery charger draw?
Volts * Amps = Watts 12 Volt * 2 amp = 24 Watts
How many watts does a 36 volt battery charger use?
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.
How many watts does a 48 volt battery produce?
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.
How many watts does a ajanta digital clock uses?
Normal clocks use little power, for example I have one that lasts 1 year with a single AAA battery.
How many watts of electrical power equal one horsepower?
One horsepower is approximately equal to 745.7 watts.
How many joules can one get out of a typical AA battery?
You get actually energy (Watts) out of a battery, not calories (which is food energy).
How many Watts in one D battery?
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.
Can you charge a battery with solar panel producing 245 watts?
You can't charge the battery with those 245 watts unless they are being 'pumped into' the battery at a higher voltage than the battery puts out. If you can exceed the voltage of the battery, that 245 watts will definitely charge a battery.
How many watts does my 12 volt 2 amp battery charger draw?
Volts * Amps = Watts 12 Volt * 2 amp = 24 Watts
How many watts solar panel do you need to charge 12v battery?
To charge any battery the voltage of the input must be more than the battery's output.
HOW MANY WATTS DOES A Halogen use?
A small one 100 watts, a large one 1000 watts or more.
How many watts does a 36 volt battery charger use?
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.
How many watts does a AAA battery produce?
A battery doesn't make any watts by itself, it has to be hooked up to a load first. And even something as tiny as an AAA battery can put out some decent watts for a brief moment if hooked up to something that'll pull a lot of amps - like a short circuit.
How many watts does an electric water heater use?
for a large one it is 4,000 watts and for a smaller one it is 1,000 watts
How many hours would a 35 watts tv last on a 12 volt battery?
To answer this question the amp/hours of the battery must be stated.
How many watts are in megawatts?
There are one million (1,000,000) watts in a megawatt.
What does 63 whr mean?
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.
