Are 12v batteries actually 13.8v?
No, 12 volt batteries are 12 volts.
How many D batteries does it take to make a 12V?
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.
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 do you wire two 12 volt marine batteries together to run a 24 volt trolling motor?
To get 24v from two 12v batteries you just link between ones positive and the others negative then connect your motor to the spare terminals, but your 12v charging system will not charge them (and any 12v equipment connected to them will burn out!) without removing the link.
Are 12v batteries actually 13.8v?
No, 12 volt batteries are 12 volts.
How do you wire three 12 V batteries to make 36 V?
The batteries should be wired in series. Electrically, it looks like this: Positive lead to car (+ -) ----- (+ -) -----(+ -) Negative lead to car Each set of parentheses represents a battery, the dotted lines are wires connecting the middle battery to the battery on each side. This will give you 36 volts at the positive and negative leads going to the car. The other option is wiring in parallel, which gives you 12V, but triples the load capacity.
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.
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.
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.
How many D batteries does it take to make a 12V?

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.
Can you use different amps on a 24V truck with 12V batteries in series?
y not?
Can you arc weld from 12V batteries?
Barely, 24v or36v in series is better
Can I connect 12 volts headlight to my 60 volts electric bike?
If the bike uses 5 12V DC batteries connected in series to achieve 60V DC you can connect the positive and negative wires from the 12V light ONLY to the first 12V battery in that series. The bike will remain 60V and the lights will be powered by the first 12V battery. If you connect the 12V light directly to 60V the light will blow instantly. Test the voltage with a volt meter before making any connections.
