Connected in series, yes.
Two 6 volt batteries in series, yes. In parallel, no.
Yes, if the two 6 volt batteries were connected together in series.
Yes
How to hook up 6 8v batteries in searise <><><> Batteries connected in series have the negative (-) of one connected to the positive (+) of the next, until all 6 batteries are connected.
You will have a 12 Volt source with double the charge capacity.
No, since in series they are 24 volts so you need to charge each one independently with the 12 volt charger. This may be done disconnected or leave them connected and put the charger on the + - of the same battery.
That would depend how they are connected. Are all Eight 6 volt batteries connected in series giving a total output voltage of 48V. Or are they connected with 2 sets of 4 batteries in parallel then connected in series to give a 24V output.
Two six volt batteries in series makes 12 volts so switch the charger to the 12 volt position.
Yes you can. Make sure the batterys are hooked together in SERIES and not parallel !!! Be sure the batterys have the correct amount of fluid in each cell to prevent "cooking " a cell.yes - the batteries must be connected together on series and the charger must be connected to one batterys pos. terminal and the other batterys neg. terminal
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.
how Can you charge multiple 12 volt batteries with a car?
No, but you can charge each one individually without separating them from the series loop.
