The Battery Charger
One battery charger is designed for 115/230 VAC and plugs
into a typical wall outlet. Another charger is designed for
12/24 VDC and is wired into the constant crane/machine
power source.
When the battery is inserted into the charger, a flashing
"CHARGE" LED lights. The charge process is terminated
by detecting peak battery voltage or after 5 hours and the
"READY" light goes on. When the "READY" light is lit, the
charger continues to "trickle" charge the battery.
