i would recommend a smart charger for your batteries
A: that is no standard or establish output from each charger. However the charger must provide the maximum current necessary to charge the battery and the voltage must always be more then the battery when has reached full charge
Yes as long as it is the right voltage: a 6v battery needs a 6v charger; a 12v battery needs a 12v charger. <><><> 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 6 volts if you want to use it to charge a 6 volt motorcycle car battery.
The charger with the 900ma output will charge the battery faster than the charger with a 500ma output. The phone with the 900mah battery will last longer between charges than that of the 500mah battery.
Depends on what you are charging and the output of the charger. That is why an automatic charger is always best. No chance of overcharging the battery.
Depends on the output of the charger which you did not list. A dead battery can be recharged with a 10 amp charger in 3 hours.
Charger Output Voltage versus Battery VoltageNO, the output voltage of a charger must be greater than the rated voltage of the battery, usually at least one and a half to two volts difference.
How long it takes to charge any battery depends on how much electrical charge it can hold. The physical size of a battery can give an indication of how much charge it may hold: the larger the battery, the more electrical charge it is likely to be able to hold. or you could just divide the mAh of the battery by the output rate of the charger. ex: 5000 mAh on a 3000 milliamp output charger would be 1hr 36min. and 3300 mAh on the same charger would be 1hr 10min. and so on.
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.
No. The charger for a car battery has an output measured in amps. You have an output measured in milliamps. There are 1000 milliamps to 1 amp. Way too small.
No set answer to that. It depends on charger output and battery capacity. Usually a few hours.
Need to know what the maximum output in amps or mA the battery charger can produce.
It is important for solar battery charger output voltage to match voltage of battery system being charged. Voltage is additive in series circuits, therefore 3 12VDC solar battery chargers connected in series would provide correct output to charge a 36VDC system.
