Connecting batteries in series (see illustration) allows a person to charge a number of batteries at one time using only one low current, high voltage charger. The amount of charge that each battery receives is indicated by the ammeter. Thus, each battery will arrive in a fully charged condition at a different time. Conditions that affect charging time are battery temperature, size, state of charge, type of battery, and other factors. Six and twelve volt batteries may be intermixed when series charging. The total voltage of the batteries should not exceed the rated voltage of the charger. Example: A Charger is rated a nominal 36 cells. Six 12 volt batteries in series or twelve 6 volt batteries in series can be charged or any combination of six and twelve volt batteries that total 36 cells. To charge batteries in series, connect the charger's positive lead to the positive post of the first battery. Connect a jumper from the negative post of the first battery to the positive post of the next battery. Continue until all batteries are connected. Attach negative lead of charger to remaining battery post.
