How Do You Charge Two 12v Batteries In Series. In the second example to charge a 24V system simply use each bank of the charger on each 12V battery. Connecting in series increases voltage only.
Next time you charge. I recently bought 2 12V lead acid batteries AGM type for my mobile music needs where I need 24V so I discharge them in series. But it doesnt keep them there as you discharge two different batteries in series.
You also dont want to do an equalization charge frequently.
Two 12-volt batteries wired in series produce 24 volts but the capacity remains the same as one for a 12-volt battery. The series connection of two identical batteries allows to get twice the rated voltage of the individual batteries keeping the same capacity. Be sure that you pay careful attention to the connection placements of each battery if you disconnect any of these batteries. Two 12 volt Batteries in Parallel One 12 volt Charger Figure 9.
