What makes car batteries work?
The reaction of the acid and lead causes electrons to move creating a DC current.
What is the voltage output of a lead-acid battery?
Voltage Outputs of Lead-Acid BatteriesThere are many different sizes of Lead-Acid batteries and the voltage output can vary.For example:Some security/alarm systems use Lead-Acid backup batteries which are either 6 Volts or 12 Volts.Similarly, emergency lights [like over doorways and hallways in commercial buildings, hospitals, etc.] use Lead-Acid backup batteries for powering the lights during power outages, and these can use either 6 or 12 Volt batteries.Most automobile batteries are 12 Volts.Some heavy vehicles [large trucks, heavy construction equipment vehicles, etc.] have 24 Volt batteries.Various aircraft use different voltage output batteries.The output voltage is dependent on the number of "cells" in the battery. A fully charged Lead-Acid cell has an output of 2 Volts DC [Direct Current].Therefore, if a battery has two cells, then the output voltage would be 4 Volts DC. If it has 3 cells, then the output voltage would be 6 Volts DC, and a battery with 6 cells would have an output of 12 Volts DC. And 24 Volt batteries have 12 cells.That is the basics. Now, there is an exception.IF the battery is "overcharged," then it can accumulate what is called a "surface charge" which goes slightly above the 12 Volt nominal output, and usually is about 1 extra volt, and that surface charge will "wither" away within a few minutes to an hour, even without using the battery. If the battery is used, then the surface charge is drained off immediately.
How long does it take to charge a 12 volt AC battery?
All batteries produce Direct current. there are no AC batteries. to charge a battery you need a DC Charger that produces a voltage that is slightly greater that the voltage of the battery. Not all batteries are designed to be recharged but the ones used in cars and trucks have large lead/acid 12vdc batteries. In motorcycles and scooters they now use smaller sealed lead/acid batteries that are in the 6 to 10 amprere range. These spaller battries should not use big amp chargers but should be slowly charged with what is called a trinkle charger that is usually less that 1 amp and take longer time to safely charge the cells. To fully charge the battery may take about 8 hours. One may also charge a small battery by using jumper cables from an automobile. In all cases watch the polarity of your connections.
How do you charge the eyeclops mini projector?
ether by the ac adapter or by the stand (4 dc batteries )
Batteries are car batteries ac or DC?
dc
What will happen if lead acid battery is charged with ac power?
It will more than likely explode. You charge the battery with a charger that coverts 120V AC to 12V DC.
What is DC jack?
A DC jack exists for the purpose of supplying direct current to a device from an external source, as opposed to the batteries inside the device. The external DC power would likely come from an AC to DC adapter that you plug into the wall. Such a jack can also work with car adapters too, provided it it converted to the correct voltage. So using an external source keeps you from using the batteries. With some equipment, that can charge the battery as well, but devices using disposable batteries are wired as to not charge the batteries.

Does wet-cell batteries and dry-cell batteries produce static electricity?
Yes. You can use a battery to charge a capacitor, which is an electrical device that stores static charge.
What type of current is produced by a battery?
Automotive lead acid batteries of 12 volts have six cells internally wired in series, each cell generating 2V. The positive plate is made of lead grid with a lead oxide paste coating and the negative plate is porous lead. Dilute sulphuric acid is the electrolyte. The lead acid battery produced a direct current or DC during a chemical reaction that turns lead dioxide to lead sulphate and sulphuric acid to water. During recharging the process is reversed.
Will a 120 volt AC to 12 volt AC adapter charge a car battery?
No, auto batteries are DC not AC.
