Can a Schumacher charger be used to charge more than one battery at a time?
Most cars and boats have 12 volt batteries, two batteries are used to gain more amperage, meaning they are wired in parallel but the voltage stays the same. Batteries wired in series (like a flashlight) give double the voltage (two 12 volt batteries wired in series makes 24 volts but your amperage stays constant.) To charge both batteries at the same time you need to make sure they are wired in parallel. The two batteries should be connected to each other positive to positive and negative to negative. Then attach the charger positive to the positive on one battery and the negative to the negative of the OTHER battery. Do not hook both leads up to one battery. It will obviously take longer to charge two batteries than it will to charge one. If they are set up to run as 24 volts (wired in series), you will either need to disconnect the jumper wire that connects the two batteries and charge them as two 12 volt batteries or use a 24 volt charger.
