I'm not 100% sure, I came on this post seeking an answer to the same question... But, I do have a general idea of how it works. Basically AC current flows from the wall socket through a cord until it gets to the weird box that is in all computer chargers. This box I assume to be a rectifier. This rectifies, or converts AC to DC thus allowing the current to flow the rest of the length of the cord and charge your battery. Trivial fact: A mac book charger has a single wire coming from rectifier to computer. How is this possible? Doesn't DC operate on two poles? Correct, it does. The charger has an inner wire and an outer wire which are insulated from each other. Hope I helped some.

Can you use 9 volt charger for 4.5 volt appliance?
No, it is not recommended to use a 9-volt charger for a 4.5-volt appliance. Using a charger with a higher voltage than what the appliance is designed for can damage the appliance or pose a safety risk. It is best to use the charger that is specifically designed for the appliance.
What is stronger 1.5 volt batter or a 9 volt battery?
A 9 volt battery is stronger than a 1.5 volt battery because it has a higher voltage. The higher voltage allows the 9 volt battery to power more demanding devices and last longer than a 1.5 volt battery.
What happens to the current in a circuit if a 1.5 volt battery is removed and is replaced by a 9 volt battery?
If a 1.5 volt battery is replaced by a 9 volt battery in a circuit, the current flowing through the circuit will likely increase. This is because the higher voltage of the 9 volt battery will provide more electromotive force, pushing more current through the circuit, assuming the resistance remains the same.
Does a 500mah battery charger charge a 4300mah 8.4 large battery?
Normally speaking, the output of a charger is stated in milliamps mA (ie 500mA) and the term mAh refers to the number of milliamps flowing for 1 hour. So for example, a 1000mAh battery will need to be charged at 500mA for 2 hours to reach full charge. In your case, I must assume that yours is a 500mA output charger and is suitable for charging an 8.4 volt battery. Theoretically at this current output, your charger will take about 9 hours to charge a 4300mAH battery. In practice the process is not 100% efficient so a 10 hour charge will probably be required.
What is maximum current of 9 volt dc battry?
The maximum current capacity of a 9-volt DC battery will depend on the specific type and size of the battery. However, for a typical alkaline 9-volt battery, the maximum current output can range from around 500mA to 1000mA. It is important to check the specifications provided by the manufacturer for the exact current rating of the specific battery model.
Can you use a 3 volt charger for a 9 volt battery?
No
Can a 9 volt charger be used to charge a 7.2 volt battery?
no
How do you reboot a rechargeable 9 Volt battery?
buy a battery charger
Can you use a 6 volt charger for a 9 volt battery?
No, the battery will be overcharged and battery damage will occur if it is done.
Can you charge a 6v battery with a 9v charger?
no, if you charge 9 volt battery with 12 volt battery you will destroy 9 volt battery
Can you use a 9 volt charger for a 6 volt battery?
This is not advised! The 9-volt charger might have a current limiter so that nothing burns up, but it any case if left on it will destroy the 6 volt battery by overcharging. A 6-volt charger is not expensive.
Can a 9 volt battery charger be used to charge a 7.2 V battery pack?
NO.
Can a 9 volt battery charger be used to charge a 4 volt battery pack?
Sort of, but any automatic cut-off won't work. You run a real risk of overcharging the battery and damage it.
Can a 9 volt battery be charged with a 12 volt charger?
Yes, a 9-volt battery can be charged with a 12-volt charger, but it's important to exercise caution. Charging a lower voltage battery with a higher voltage charger can lead to overcharging, overheating, and potential damage or safety hazards. It's advisable to use a charger specifically designed for the type and voltage of the battery to ensure safe and effective charging.
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 charge a 9 volt battery with a 12 volt charger?
no, there is a high probability that it will explode
Can I charge a 12 volt battery with a 9 volt charger?
Unfortunately No. Voltage potential is such that electric current will flow from a higher potential towards a lower potential in much the same way that water will flow from a high level to a lower level until it reaches equilibrium (balances out on both sides). If the battery is completely discharged then a 9 Volt charger may bring the battery up to around 9 Volts but it will never go above equilibrium. Connecting a fully charged 12 Volt battery to a 9 Volt charger will cause current to attempt to flow "backwards" into the charger. If the charger has (as many modern ones do) overload and other protection devices then the charger will simply shut down but if the charger has no such protection, it could cause permanent damage to the charger and, depending on the rate that the battery discharges, the battery could explode and one or both devices could in fact set on fire. Electricity can be potentially very dangerous and you should always ensure that you are using the correct equipment designed for the job. If in doubt, always seek professional advice.
