How many 12 volt batteries does it take to power a 3000 watt invertet for 24 hours?

You need 3000 x 24 watt-hours or 72,000 watt-hours. A typical car battery has a capacity of 50 Ah or 600 watt-hours, so you would need 120 car batteries, connected in the right combination of series and parallel to give the right voltage for the inverter.

Why cant you use batteries to power kettles?
Standard electric kettle normally takes about 1600-3000 watts to operate. No modern batteries can supply this kind of power for the needed period of time (about 3-5 minutes).
How long is 3000 hours in years?
3000 hours = 0.342 years.

Can you downgrade psp 3000 6.2?
No, Pandora Batteries (the only known way to downgrade PSPs) do not work with the PSP-3000, and, as such, you can not downgrade it.
About how much flying time can I expect to get from the batteries in my radio-controlled plane?
A 4.8V battery offers about 2000 machine hours. Other voltages can offer as much as 3000 machine hours. Depending on the make and model of your plane, the flying time will vary.
How many minutes are in 50 hours?
multiply 50 by 60 because 50 hours you said and 60 minutes in a hour. That will give you 3000.

What is the difference between Wh and Mah on a battery?
These are two common ways battery capacity is measured. Wh stands for "Watt hours", and it's a measure of the actual energy content of the battery; it measures how much power (watts) the battery can supply multiplied by the number of hours it can do so before it runs out. Most batteries are labeled with a capacity in mAh (milliampere hours). This is a measure of the electric current the battery can supply multiplied by the number of hours it can do so. Example: if a battery is labeled 3000 mAh, it should be able to supply 3000 mA of current for one hour, 1500 mA of current for 2 hours, etc. You can figure out the Watt hours for a battery by multiplying the voltage of the battery by the amp hours (amp hours = millamp hours / 1000).
How many hours or days is 3000 minutes?
Since there are 60 minutes in one hour, then 3000 minutes = 3000/60 = 50 hours Since ther are 24 hours in one day, then 50 hours = 50/24 = 2.083 days
How many watt hours in AA battery?
This question doesn't have a simple answer. It depends on the battery chemistry and construction. Somewhere in the battery's specification is the amp-hour rating. For AA size batteries, it is common to use milliampere-hour ratings (mAH). You need to multiply the mAH rating by 1.5 if you're figuring alkaline batteries, or 1.2 if you're figuring rechargeable batteries. Then divide the result by 1000 to get watt hours. Nicad cells are typically rated 500 to 1000 mAH. NiMh batteries typically have twice the rating of similarly sized nicad batteries. Alkaline batteries are typically rated at 2500-3000 mAH
How much mAh does two AAA baterries have?
From 600 to 5400 depending on type.So it depends on the capacity of each battery.Non-rechargeable zinc-carbon AA batteries may have a rating between 400-900 mAh.'Long-life' (zinc chloride) batteries last for about 1000-1500 mAh.AA re-chargeable (alkaline) batteries carry a rating in milliampere hours (mAh). e.g 1700 mAh, 2100 mAh, 2450 mHa etc., up to about 3000 mAh.The higher the rating the longer it will last for any given usage at a constant temperature. (Even without usage there will always be some drainage of power over the months)Two batteries will have more power than one battery, but the way that the power is used by the equipment and the 'cell-balancing' between the two batteries will affect the total life that can be expected from a power unit of two AA batteries.For more information, see 'Related links' below.
