To charge two 12 volt batteries in series youd need a 24 volt charger. Thats the pat answer.

How to charge two 12 volt batteries in series. Two or more 12 volt batteries wired in parallelpositive to positive negative to negativeis still a 12 volt system. Charge more than five batteries by connecting one 12 volt battery charger across each battery in the series as if each battery were the only one being charged. For charging 6 volt batteries in series with a 12 volt charger you can use a single charger. You need to overcome the total voltage of the series batteries 12 v 12 v 24 v to drive electrons. Two 12 volt batteries wired in parallel continue to produce 12 volts but the capacity doubles. Two 12 volt batteries wired in series produce 24 volts but the capacity remains the same as one for a 12 volt battery.
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. Charging 12 volt batteries wired in parallel requires a 12 volt battery charger. Charging only some of the batteries will result in batteries attempting to equal out the power and charging each other. Connecting batteries of different voltages in series. A 6 volt battery is often three 2 volt cells and a 12 volt battery is usually six 2 volt cells. Two or more 12 volt batteries wired in seriesthe positive terminal of.
You do not need to disconnect the series connections to do this as long as you can access just the lowest battery. Batteries may be wired in parallel or in series. Charge all the batteries at the same time. Next time you charge you should see the batteries are then closer in. The easiest way to fix a voltage difference is to charge the pack fully then bring up the lowest battery with a 12v charger placed on just the lowest battery. 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.
