Charging From AC Power

Using an Alternator Controller
If your regular alternator is inadequate by itself, you can
install an alternator controller that will bypass the voltage
regulator and boost the alternator’s output voltage during
charging. This will increase the alternator’s charging rate at
higher battery voltages and ensure more rapid and complete
charging. Alternator controllers are available from marine
product dealers.
Using a High-Output Alternator
Heavy-duty alternators rated from 100–140A can replace
standard alternators and produce the higher current and
voltage required to charge multiple battery systems. They are
available from RV and marine dealers as well as auto parts
suppliers.
Charging From AC Power
When recharging from AC power, use a good quality marine
battery charger or RV converter that meets the requirements
outlined in “Charging System Requirements” on page 38. For

Do not use chargers intended for occasional recharging of
automotive starting batteries. These chargers are not intended
for continuous use.
