Multiply the vots by the amps to find the volt-amps. Or divide the volt-amps by the voltage to find the amps.
A 10 amp charge will only output 10 amps and 12 volts. So, if you want to charge thee 12 volt batteries hooked in series you will have to disconnect the positive cable from each battery and charge then individually. You cannot charge three 12 volt batteries hooked in series. That requires a 36 volt charger.
Depends on the battery. It is listed on the battery as Cold Cranking Amps (CCA).
you will need 21.81 amps at 220v
8,33 Amps
2.083 amps
62.5 amps
it draws 210 amps
watts = volts * amps--> Amps = watts/ volts therefore; 2000/220= 9.09 amps
at 240/50 volt itequates to 4amp
2.3kw
55/12=4.6
