What do you do to change the voltage of a 12 volt battery to a 6 volt output?

Questions can't be answered. Too many unknowns in the equation. Need the watts, or the resistance (ohms) for the formula.

Can you use any 220 volt adaptor on a 110 volt appliance?
No. 220V adaptor can't control the output voltage, 110V appliance will be fry. Use instrument transformer or voltage regulator instead.
Can you charge a 28 volt Gill aircraft battery with a 12 volt car charger?
No, the battery charger has to match the voltage of the battery it is to charge.
Can a 12-volt solar battery charger charge a 36-volt battery?
No, a 12-volt charger cannot charge a 36-volt battery. The electrical potential difference across the leads of a charger must exceed the electrical potential difference across the terminals of any battery it is expected to charge. And 12 volts is much less than 36 volts.WHY?The 36-volt battery would require at least 39.3 volts to get to a float charge. This would charge the battery to 80% quickly, and then take a logarithmic period of time to finish the battery. To actually charge the 36-volt battery correctly would require roughly 43.2 volts, but if we can't get 39, this is irrelevant.The 12-volt charger has no chance.The answer above is correct; there is no way the 12-volt charger can charge a 36-volt battery. However, the voltages given apply only to lead-acid batteries. They would be different for nickel metal hydride or lithium cells. You still need a charger with more voltage that the battery voltage in any case.
Does a 9 volt battery have more energy than a 1.5 volt battery?
A D cell battery has a voltage output of 1.5 volts, while a 9 volt battery produces about 9 volts. This is just the potential energy though. D cells provide far more current for a longer time then a 9 volt battery. In terms of overall power output, a D cell in give you many times more power than a 9 volt battery. Physical size, in this case is a good indicator as the material inside is the same.
Can you use a 12 volt charger to charge 14.4 volt battery?
Yes. The voltage of charger has to be slightly higher than the battery for it to be able to charge the battery.
Can use 14.4 volt charger to charge 18 volt battery?
Charger Output Voltage versus Battery VoltageNO, the output voltage of a charger must be greater than the rated voltage of the battery, usually at least one and a half to two volts difference.
What does 12 volt mean in the context of a battery?
It means the voltage output of the battery is 12 volts DC.
What does it mean to say that your car has a 12V battery?
12 Volt BatteriesThe 12 Volt designation of a battery indicates that the nominal output voltage is 12 Volts.
Can you charge an 8 volt battery with 6 volt charger?
No, you cannot charge an 8 volt battery with a 6 volt charger. The voltage of the charger must match the voltage of the battery.
What will happen if you use a 14 volt output in a 12 volt input?
Shouldn't be a problem. For example the unloaded voltage on a car battery is often around 14 Volts. Under load the voltage reduces.
Can a 12v solar panel charge a 12v battery?
If the 12 volt solar panel output voltage is always higher than the 6.5 watt battery voltage. To charge a battery, a voltage greater than the battery must be applied to the battery, otherwise the battery will try to charge the charger.
What does a battery temperature sensor for a Plymouth neon do?
The battery temperature sensor is used to fine tune alternator output for better fuel economy and longer battery life. Note, this change is alternator output is very minimal and typically cannot be detected using a Digital Volt Ohm Meter (DVOM). However, if the charging system is hooked to a lab scope, a change in alternator output will be detected. This change is typically seen in amperage output, not voltage.
Your volt meter reads 16 volts at the battery at idle The alternator and voltage regulator have been replaced Do you have a problem?
Alternator Output Voltage RangeGenerally, alternator output voltage is consider OK if it is in the range between 12 1/2 volts to a maximum of 16 volts.Therefore, although the output is at the maximum, you do not seem to have a problem.Usually, if the battery has had a lot of drain, then the alternator output will run at the maximum until the battery is fully charged.
Can a 7.5 volt charger be used on a 9 volt appliance the appliance is a weighing machine?
No. The voltage of the charger's output is only 7.5 volts. This is not high enough to charge a 9 volt battery device.
Can you connect a 12 volt auto alternator to a 24 volt system to charge the batteries?
If you connect an alternator that has been designed for charging a 12 volt battery to any 24 volt system in an attempt to charge its batteries, that alternator will not work because of either of two different reasons:if the 24 volt battery is completely dead or flat the 12 volt alternator will not be able to charge it to much above 18 volts. That is about as much practical use as having a flat 24 volt battery!if the 24 volt battery is not "flat" but has a voltage that is in its normal range - between about 23 volts and 27 volts - the 12 volt alternator would not do anything because its output voltage cannot go high enough.Some more facts:12 volt systemsAn alternator designed to charge a nominal 24 volt battery will have a voltage and current regulation system to control its output voltage between about 13.5 and 18 volts and an output current that could vary between zero and about 40 or 50 amps.The overall range of current amperage output from the alternator would vary from vehicle to vehicle depending on the sizes of the alternator and battery and those in turn would be sized to match the likely normal current amperages drawn by the vehicle's ignition, night-time road lighting, air conditioning and other systems.The actual charging voltage and current being output from the alternator at any instant depends on the "state of charge" of the 12 volt car battery. A nominal 12 volt lead-acid type car battery that is flat has a voltage of about 11.5 volts or less. One that is fully charged would have a voltage of about 13.5 volts.24 volt systemsAn alternator designed to charge a nominal 24 volt battery will have a voltage and current regulation system to control its output voltage between about 27 and 36 volts and an output current that could vary between zero and about maybe 80 or 100 amps.The overall range of current amperage output from the alternator would vary from vehicle to vehicle depending on the sizes of its alternator and battery and those in turn would be sized to match the likely normal current amperages drawn by the vehicle's ignition, night-time road lighting, air conditioning and other systems.The actual charging voltage and current being output from the alternator at any instant depends on the "state of charge" of the 24 volt vehicle battery. A nominal 24 volt lead-acid type battery that is flat has a voltage of about 23 volts or less. One that is fully charged would have a voltage of about 27 volts.Only in the instance where two 12 volt batteries were connected in series to produce power for a 24 volt system, could a method be devised to use a 12 volt alternator to charge the batteries independently.
Can you hook more than one solar battery charger in series to charge a 36 volt system?
It is important for solar battery charger output voltage to match voltage of battery system being charged. Voltage is additive in series circuits, therefore 3 12VDC solar battery chargers connected in series would provide correct output to charge a 36VDC system.
What is a 2007 Trailblazer alternator output voltage?
The alternator output voltage in most modern 12 volt automotive systems ranges from 13.5V to 14.5V, with the nominally accepted value being 13.8V. The actual voltage depends on battery charge state and temperature.
