Different batteries have different capacities, and will therefore store a different amount of energy - and require a different power if you want to charge them in the same time.

To calculate the wattage needed to charge a 12V battery in 6 hours, you need to know the battery's capacity in amp-hours (Ah). Once you have the Ah rating, you can use the formula Watts = Volts x Amps to determine the wattage required for charging. Multiply the battery's voltage (12V) by its capacity in Ah, then divide by the charging time in hours (6 hours). This will give you the minimum wattage needed to charge the battery in 6 hours.

What does 5 watt hours means in terms of battery use for a camcorder?
It means you can run whatever off the battery as long as power x time = 5. Ten watts for 0.5 hours. Five watts for 1 hour or 2.5 watts for 2 hours.
A battery charger uses 15 watts At 6 cents per kilowatt-hour how much does it cost to charge batteries for 24 hours?
To find the cost, we first calculate the energy consumption in kilowatt-hours by converting the watts to kilowatts (15 watts = 0.015 kW) and multiplying by the number of hours (0.015 kW * 24 hours = 0.36 kWh). Then, we multiply the energy consumption by the cost per kilowatt-hour (0.36 kWh * $0.06/kWh = $0.02 or 2 cents). So, it would cost 2 cents to charge the batteries for 24 hours.
How many hours will 3600 watts last on a 637 amp battery?
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.
How many amps and watts are in 12 volts?
The two are not related. Voltage is a measure of electrical potential, and watts is a measure of the work performed by an electrical device. Power equals volts times amperes. So you have to look at your fuse, e.g. 3 amps and calculate: 12 volts times 3 amps equals 36 watts.
How many watts in one battery?
The wattage of a battery depends on its capacity and voltage. To calculate the total watts, multiply the battery capacity in amp-hours by the voltage of the battery. For example, a 12V battery with a capacity of 100Ah would have a wattage of 1200 watts (12V x 100Ah).
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 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.
What does 5 watt hours means in terms of battery use for a camcorder?

How many watts to charge a 12v battey direct in 6 hours?
Different batteries have different capacities, and will therefore store a different amount of energy - and require a different power if you want to charge them in the same time.
How long W light on ah battery?
The problem here is that "Ah" (ampere-hours) is not a unit of energy. To convert that to units of energy, you need to multiply by the voltage of the battery. The result, of course, will vary depending on the battery type.The result of this multiplication would give you ampere-hours-volts, or watts-hours (watts times hours). Therefore, you can then divide by the number of watts used, to obtain the time (in hours).
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 solar panel need to charge 12volts 7ah battery?
1 watt will do the job.
A battery charger uses 15 watts At 6 cents per kilowatt-hour how much does it cost to charge batteries for 24 hours?

How many watts solar panel do you need to charge my 12v 100amp battery in 6 hours if you use 5.5amp a hour?
There is too much information there. Charging a 100 amp-hour battery fully would take 18 hours at 5.5 amps, or 6 hours at 16.67 amps. At 5.5 amps the power would be 12x5.5 or 66 watts, and this is the rating of the solar panel required. That would be about 0.4 of a square metre.
Can you charge a battery with solar panel producing 80 watts?
You sure can! I charge a marine battery with a 75 watt panel and it goes from a fairly good discharged state to fully charged in about four days.
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.
