It takes eighth batteries. each battery, being AA, A , C,or D have 1.5v per cell. if you put them all in series; neg. - pos., neg - pos., and so on it will take eight D batteries to make 12 volts.

Are 12v batteries actually 13.8v?
No, 12 volt batteries are 12 volts.
How many torch batteries needed for earthquake?
Enough to last two or three days in all of your flashlights. If you have a 12V adapter, you can sometimes recharge rechargeable batteries from a car or truck outlet.
How can the 250watt PC power supply unit be replaced with a 12v 4ah batteries and how many batteries you need and how would it be connected to make the PC work on batteries for 2h?
First find the current which is 250/12 = 21A rounded off. So you would need 6 of the batteries in parallel to get a bit more than 1 hr and probably 11 batteries in parallel would provide around 2 hours of operation. This is not precise since the power supply wouldn't always consuming 250 watts of power.
How many amps in 12v 150w?
Volts * Amps = Watts 12V * A = 150W A = 150W/12V A = 12.5
How many watts to charge a 12v battery 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.
Explain why a 24v system that runs off of 4 batteries which includes a 12v feed- that's powered by two of the batteries are getting no charge from the alternator.. the other two are charged well.?
With the batteries in series, the alternator provides the same current, and therefore the same charge to all the batteries. The alternator can take no account of any current being drawn from the 12V take off point. Part of the charge current is being fed to the 12V load and not to the batteries. Therefore, the 12-24V batteries are being fully charged while the 0-12V batteries are being partially charged. Over a period of time, the difference between the charge levels will become more obvious.
Are 12v batteries actually 13.8v?
No, 12 volt batteries are 12 volts.
What batteries do TF Gear Mag Runner bite alarms take?
The TF Gear Mag Runner bite alarms take LR1/N size batteries.
How do you wire four 12 volt batteries to get 36 volts and 48amps?
Four 12V batteries may not be connected end to end to obtain 36 Volts. But four 12V batteries can be connected end to end to provide 48V and push 36 amps. The actual answer to your question suggests that you drop one 12V battery and use three, not four 12V batteries end to end to obtain 36V.
How many hours do the 12V 200AH batteries last to run 1000W lamp?
Approx 5 hours
How many 12v 12ah batteries are required to run 320watts motor?
it depends how many hours do you want it to run, but basically 3 batteries should be enough for a little more then 1 hour
How many 12v batteries could be use to power 500kva ups?
Well unless you mistyped something 500kva is 500,000 watts. That would be 41,666 12 volt batteries!
You want to take 25ams output you are having 16 Nos of 12V 8Ah batteries do you have to connect batteries in series of parallel connection?
Parallel or Series Connections for BatteriesTo increase current [measured in Amperes], you connect batteries in parallel. To increase voltage, you connect batteries in series.
What is the difference between 12V automotive and 12V marine batteries?
without knowing exactly the types of batteries you are talking about but generally marine batteries are a higher quality battery and have higher amp hour ratings which basically means they can turn the stater for longer
What is the voltage that is carried out by automobile batteries?
Virtually all automotive batteries nowadays are nominal " 12V " batteries, but will measure up to 13.6V when fully charged.
How many torch batteries needed for earthquake?
Enough to last two or three days in all of your flashlights. If you have a 12V adapter, you can sometimes recharge rechargeable batteries from a car or truck outlet.
What is 12V and can be used to create a fire?
12V is probably short for 12 volts, the voltage used by regular car batteries. And since 12V can strike a spark, it can be used to start a fire.
