Charging a 6-volt battery is no different than charging other voltage batteries, but you do need to ensure that you are using the correct charger. Therefore, both configurations can be charged by any 12-volt battery charger by simply connecting the charger’s red cable clamp to the “plus” 12-volt terminal lead and the black or ground cable clamp to the negative terminal, as shown here. The final output that provides battery power to the components in the RV is still 12-volts DC. This works because, in a series circuit, current has only one direction or path to take, and, as a result, it remains constant throughout the circuit while the voltage changes with each battery connected in series.

Plug the power cord into a wall outlet as far away from the battery as the cord and cables will allow. For example, you can connect two 6V batteries in series with a 12V source to recharge them. The battery continues to charge even when the laptop is turned off. By short, I mean that you connect the two terminals (positive and negative) directly so that the battery simply drains. Turn the battery charger's power switch on.
