Can you use a 6V 2amp adapter on a 6V 600mA device?

No. You need to use the exact battery charger for the battery specified by the manufacturer, in order to achieve the correct charge cutoff point. In particular NiCad and similar batteries detect full charge by detecting the knee point in voltage per unit time given a specific charge current. Using the wrong charger could result in overcharge which will damage the battery.


Can a 9v charger be used in a 12 v battery?

No.


Can you charge a 9V Battery with a car alligator clip charger?

No. For one thing, you can't recharge just any old 9volt battery; it has to be a specially-designed rechargeable for which there is a specially designed charger. For another, a car battery charger puts out about 13-15 volts.


Can a 9 volt battery charger be used to charge a mobile phone?

Most of the mobile phones have batteries of less than 5V rating, mostly up to 3.7V.Chargers are typically rated for less than 5V.Caution: It is not safe to charge these with a 9V charger. The battery may explode..


Can Charge 9v with 12v dc power?

No, not possible. The charger has to go to higher volts than the battery being charged.


Can a lithium ion-polymer battery ever be charged in a NiMH charger since someone finally invented a 9V 8.4V lithium-polymer but the only charger specifically supporting it is their expensive one?

****NEVER USE AN NIMH BATTERY CHARGER TO CHARGE A LITHIUM OR LITHIUM-ION BATTERY!**** I get asked this all the time. Using an NiMh charger to charge this battery will make it EXPLODE or CATCH FIRE. The fire CAN NOT be extinguished with water and CAN NOT be extinguished with a household fire extinguisher.


Where can you find a battery charger for NiMH 9v batteries that can charge the battery to 10v?

I doubt you'd find one ! NiMH batteries charge to 7.2 volts NOT 9 volts ! Trying to charge one to 10 volts is overcharging by almost 50% ! This will certainly shorten the life of the battery and COULD result in overheating and/or explosion !


What is stronger a 1 amp battery charger or a 9v battery?

You cannot compare these two totally different things. As far as amperage the charger puts out more amps if it is an auto battery charger and also puts out 12 volts. If you are talking about a 9 volt battery charger then the battery may or may not be more powerful, it depends on how many mii-amps the charger is putting out.


Can you charge a leydon jar with a 9v?

Yes, you can charge a leydon jar with a 9V battery. After all, a leydon jar is just a capacitor. A typical leydon jar is about 1nF, so you would not be able to do much with a potential difference of only 9V.


Can a 6 volt adapter be substituted for a 9 volt adapter?

No, of course not. The 6v adapter only produces 6v, while the load expects 9v.


Can you substitute 9v dc for 6v dc?

Substituting a 9V DC power supply for a 6V DC supply is generally not advisable, as it can lead to overvoltage conditions that may damage the device designed for 6V operation. Components may overheat or fail, and the device may not function correctly. Always check the specifications of the device to ensure compatibility with the power supply voltage. If a 9V supply is required, consider using a voltage regulator or a suitable step-down converter to safely reduce the voltage to 6V.


Will a 9V 300 mA charger work as a 9V 300 mA adapter for a Vtech Vsmile game as I bought a charger by mistake?

Sure thing. The voltage is correct, and it has enough capacity. Make sure that you get the negative and positive polarity right if you are putting your own connector on. Usually they have a graphic, showing that negative is in the center of the plug, and positive on the outer etc.
