3.2.9 Battery Charger Options
When so equipped, a battery charger can be used for charging genset starting and control batteries.
These chargers are current limiting and supply automatic constant voltages.
When the battery approaches the full charge preset voltage, the charging current automatically tapers to
zero amperes or to a steady-state load on the battery.
A float-charge battery charger regulates its charge voltage to continuously charge without damage to the
battery. As the battery approaches full charge, the charging current automatically tapers to zero amperes
or to steady-state load on the battery.
Two battery chargers are available (see Figure 18). One battery charger is rated for 2 amperes at 12 or
24 VDC. The other battery charger is rated for 15 amperes at 12 VDC or 12 amperes at 24 VDC.
