Check the internet to see if your charger will automatically step down to 7.2V (not likely if the charger is not the same brand as the battery). If it does not step down then it is possible but *** not recommended ***. Overvolting can cause nasty caustic leaking of toxic chemicals from the battery.
A: YES the trick is to make sure not to overcharge the battery. Batteries needs a set of input current as max requirement otherwise they overheat. any voltage above the 7.2v is satisfactory provided the current is limited to specification.
Rf80-k aircrfat battery charger can charge all type of batteries dry and wet cells
Nope.
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.
Unless it's an old vw bug, cars usually run on a 12 volt dc system nowadays. Motorcycles often run on a 6 volt dc system. Different systems require different charging voltages so you won't ever be able to charge a 12 volt car battery from a 6 volt motorcycle battery charger as the output voltage would be way too low. However, if you can set the battery charger's output to give either a 6 or a 12 volt output, then you must always remember to set it to 12 volts if you want to use it to charge a 12 volt car battery.
The formula you are looking for is I = W/E. Amps = Watts/Volts. 300/24 = 12.5 amps. A good charger with an output of 15 amps will do the job nicely. The time that it will take to charge the battery will depend on the amp/hrs of the connected battery and the state of discharge that the battery is in when charging starts.
It sounds like you have nickel-cadmium batteries, since 7.2 volts is an integral multiple of 1.2 volts. You should notcharge a nickel-cadmium battery with any charger that is not specifically designed for it. The issue is that overcharging these batteries will damage them, and that the battery voltage alone is not enough to determine state of charge. (You have to measure the slope of the voltage, and detect the inflection point which occurs at full charge. This is a very specific thing, so the battery must be matched to the charger.)
NO.
No, not possible.
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.
You do not charge a 7.2 volt battery with a 9.6 volt charger period unless you want to ruin the battery. You charge it with a 7.2 volt charger.
yes!! it can be easily charged
No, the battery charger has to match the voltage of the battery it is to charge.
No, a 12 volt charger will overcharge a 8 volt battery and destroy it.
No.
No, an automobile battery charger outputs 12 Volts. This is far too many volts to charge a 5 Volt battery. You would destroy the 5 Volt battery with this charger.
Charge it with a 12 volt battery charger.
If you are asking the question, can you charge a 6 volt battery with a 12 volt charger, the answer is no.
A 12 volt battery charger is designed to charge 12 volt batteries.The answer to the Related Question explains how any battery charger works.
