Some of these chargers will have multiple output leads, or banks. These are designed to produce 12 volts to each bank, which in turn allows for each battery in your system to receive an individual charge so it is fully optimized each time it is charged.

There is no need to disconnect the batteries in series from each other, and no need to disconnect the charger from the batteries. Just plug it in and walk away, knowing that your batteries will be ready when you are.

*Exclusions may apply for large, oversize items.  Flat Rate shipping is for the lower 48 states only.
