WARNING
Electric Shock Hazard
Batteries present the risk of high short circuit current.
Remove watches, rings, or other metal objects. Use tools with insulated
handles.
NOTICE
Servicing of batteries must be performed or supervised by personnel
knowledgeable of batteries and the required precautions. Keep unauthorized
personnel away from batteries.
When the battery voltage falls below approximately 13.2 VDC, the charging current
will be constant at 4 Amps. When the battery voltage reaches 13.2 VDC, the
charger automatically returns to float mode. As soon as the charging current value
falls below 0.3 Amp, the charging indicator will turn off.
There are two LED indicator functions:
• POWER: power supply indicator, illuminated when the charger is connected to
AC power.
• CHARGING: charging indicator, illuminated when charging current exceeds 0.3
Amps.
