How to charge 2 12 volt batteries in series. For charging 6 volt batteries in series with a 12 volt charger you can use a single charger. Connect the positive terminal of one battery to the negative terminal of the other. Nick miller can you hook 2 12 volt batteries in series and parallel with 2 battery on off switches. Two 12 volt batteries wired in series produce 24 volts but the capacity remains the same as one for a 12 volt battery. Connecting batteries of different voltages in series. To charge two 12 volt batteries in series youd need a 24 volt charger.
There will be 24 volts about 28 volts with an alternator if two 12 volt batteries are wired together in series. Knowing the difference between series and parallel circuits to charge batteries can help you improve the efficiency of your batteries through different methods as a result of the varying physics between series and parallel circuits. Then connect the negative end of the first battery to the positive end of the second one and connect the negative end of the second battery to the negative output wire in black of the charger. Two 12 volt batteries wired in parallel continue to produce 12 volts but the capacity doubles. In theory a 6 volt 5 ah battery and a 12 volt 5 ah battery connected in series will give a supply of 18 volts 6 volts 12 volts and 5 ah. Batteries may be wired in parallel or in series.
You need to overcome the total voltage of the series batteries 12 v 12 v 24 v to drive electrons. Im trying to be able to switch from series to parallel with 2 on off switchesone switch on while the other is locked and off and only change voltages while both switches are off im trying to run 2 different voltage. In order to charge the batteries you can use either a 6 volt or 12 volt battery charger it all just depends on how you want to charge them. For two 6v batteries you can connect the positive output wire in red of the charger that is 12 or more volts to the positive terminal of the first battery. Charging 12 volt batteries wired in parallel requires a 12 volt battery charger. Obviously with both switch off while changing from series and parallel.
If you want to charge both together then you will need to use the battery charger in 12 volt mode if applicable and at the end of the series.
