NOTE: Do not connect a VRLA (valve
regulated lead acid) battery. To charge
a VRLA battery, a special (constant-
voltage) battery charger is required.
NOTE: Do not connect any load to battery or
use engine starter motor while
charging. This causes high current to
fl ow through generator which will burn
out coil.
NOTE: Prior to charging battery, remove
positive and negative cables to battery.

Operating Range of DC Power Supply
(Charging 12V battery only):
This power source is designed to charge
batteries up to 40Ah that are half-discharged.
Do not charge batteries of a higher capacity
than 40Ah.
12V Battery:
Time required for recharging a battery varies
depending on discharge level of battery. When
specifi c gravity of battery reaches 1.26 to 1.28,
charging is complete. When charging, check
battery's specifi c gravity once an hour. Average
time for charging a half-discharged 40Ah
battery is approximately 5 hours. Be sure to
check battery fl uid level before charging.
DC Circuit Protector
NOTE: Reduce load of connected electric
device below specifi ed rated output of
