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.
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.
Yes, a fully charged 12V battery can measure around 13.8V. This is because the voltage can vary based on factors such as the state of charge and temperature of the battery.
Yes, you can power a 12V light strip using AA batteries, but you'll need to connect multiple batteries in series to achieve the required voltage. Specifically, you'll need eight AA batteries, as each standard AA battery provides about 1.5V. However, keep in mind that this setup may not provide a long-lasting power source, as AA batteries can drain quickly depending on the light strip's current draw. Additionally, consider using a battery holder and a method to connect the batteries securely for safety and efficiency.
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.
When connecting two 12V batteries in series to create a 24V system, the wires can get hot due to resistance in the wires and the current flowing through them. If the wires are undersized for the load or if there is a poor connection, the increased resistance leads to power loss in the form of heat, as described by Joule's law (heat generated is proportional to the current squared times the resistance). Additionally, if the batteries are not balanced or if there is a short circuit, excessive current can further exacerbate the heating issue. Proper wire gauge and secure connections can help mitigate this problem.
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.
Hi, They take the little 12v batteries, same as for hand held digital camera's.
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.
Approx 5 hours
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
Well unless you mistyped something 500kva is 500,000 watts. That would be 41,666 12 volt batteries!
Parallel or Series Connections for BatteriesTo increase current [measured in Amperes], you connect batteries in parallel. To increase voltage, you connect batteries in series.
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

Virtually all automotive batteries nowadays are nominal " 12V " batteries, but will measure up to 13.6V when fully charged.
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.
y not?
