No! and you might have a nasty fire with sulphuric acid spilling everwhere.
A battery pack is always DC and it must always be charged with DC. It must also have a device for limiting the charging current, and good chargers also cut the charging current off when the right voltage is reached.
Nope.
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.
To charge a battery, the charger voltage must be higher than the battery voltage. If a AA battery (or any other) has a normal voltage of 1.2V the charger voltage must be at least 1.2V. The type of voltage supply and its current capability is immaterial. No, the charging voltage have to be larger than the battery voltage, to charge 2 AA batteries, that is 3 volt if connected in series, so a voltage of at least 4 volt is needed
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.
resister is nothing but a 'clay' which will reduce the flow of current. There by limiting the volt.
It is not recommended to use a 12 volt 1200mah charger to charge a 9.6 volt Ni-MH 3500mah battery pack as the voltage and current ratings are different. Using a charger with a higher voltage may damage the battery pack and pose a safety risk. It is important to match the charger voltage and current ratings to the specifications of the battery pack.
NO.
yes!! it can be easily charged
No. It requires more that 8.4 volts to charge a 8.4 volt battery. If the 8.4 volt battery is discharged to less than 7.2 volts then it might charge up to 7.2 volts but no higher. Once the voltages are the same then current stops flowing and charging stops.
The answer depends upon the construction of the 6 volt battery. If you can treat it as two 3 volt batteries then the answer is YES otherwise NO. Charge each section separately inserting a low wattage torch bulb between the charger and battery cell to limit the current. Choose the bulb to prevent execissive charging rate; an ammeter would come in handy. The main risk is EXPOSION if you charge too fast! Put the battery to be charged inside a strong box for safety. If in doubt buy a new battery charger, they are cheap.
Sort of, but any automatic cut-off won't work. You run a real risk of overcharging the battery and damage it.
It is not recommended to charge a 19.2-volt Craftsman battery pack without using the appropriate charger. Using the wrong charging method can damage the battery pack and pose a safety risk. It is best to use the correct charger provided by the manufacturer to ensure safe and efficient charging.
NO, a 12 volt battery cannot be charged with a 6 volt charger. To charge any battery, the charging voltage has to be, at least, slightly higher than higher than the voltage of the battery. Current flowing through the battery is what accomplishes the charging, and no current will flow at or below the voltage of the battery to be charged.
No
Yes. A battery draws what it needs from the charger, the charger does not force current into the battery. The voltage spec. is the same. Things would be different if you were to try to charge a five volt battery with a ten volt charger. You would probably blow the battery. Hope this helps.
Depends entirely on how much current you use to charge it.
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.
