Step 2: Series Connection for 24 Volts For those seeking a 24-volt setup, connect the batteries in series:

  1. Connect the negative terminal of one battery to the positive terminal of the other using a battery cable.
  2. This arrangement effectively doubles the voltage from 12 to 24 volts.

Alternatively, for jump-starting purposes, refer to your vehicle’s owner’s manual for specific instructions.

Can You Run Two Batteries on One Alternator?
