Operating range of DC power supply
(exclusively for charging 12V battery)
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
The time required for recharging a battery varies
depending on the discharge level of the battery. When
the specific gravity of the battery reaches 1.26 to 1.28,
charging is complete. When charging, check the bat-
tery’s specific gravity once an hour.
The average time for charging a half-discharged 40Ah
battery is approximately 5 hours. Be sure to check the
battery fluid level before charging.
9 Do not connect any load to the battery or use
the engine starter motor while charging. This
causes high current to flow through the gener-
ator which will burn out the coil.
9 Do not connect a VRLA (Valve Regulated Lead
Acid) battery. To charge a VRLA battery, a spe-
cial (constant-voltage) battery charger is
required.
