Automatic Current Limiting
When batteries are severely discharged, some battery chargers can be overloaded
due to the high charging current required. The Auto Charge 1200 contains an
automatic current limit. This circuit limits the output current to the rated 40 amperes
when charging a deeply discharged battery or if the starter cranks the engine while
charging. The current limiter thus eliminates the need for an ignition interlock
circuit.
Battery Charge Condition Indicator
This indicator shows the charge condition of the battery in 10 levels from “LOW
CHARGE” to “FULLY CHARGED”. This device indicates a defective battery when
a bar graph does not rise to the “FULLY CHARGED” level after an extended period
of charging.
NOTE: If a battery is being charged with an external load of 4 to 10 amperes
across it’s terminals, the bar graph may move down 1 or 2 levels. This
does not indicate a defective battery.
