Engine Start; Overload Protection - Schumacher Electric CBC 7600 Instruction Manual

FEATURES

ENGINE START

The ENGINE START setting on the RATE/VOLTAGE CONTROL switch provides high current
to crank-assist or start a vehicle with a discharged battery. This feature helps you start the vehicle
to drive it to a location for service.

OVERLOAD PROTECTION

The charger uses output circuit and thermal breakers to prevent overheating and damage to the
charger and vehicle.
DETERMINING THE STATE OF CHARGE
The state of charge is a percentage of the battery charge at a certain temperature. To determine
the state of charge, use a hydrometer, voltmeter, or battery analyzer, depending on the type of
battery you are charging.
NOTE: For the CBC 7700, you can use the percentage scale on the voltmeter as the state of
charge.
For a refillable-top battery, use a hydrometer. A hydrometer is a syringe that takes battery acid
from battery cells to indicate the gravity of the battery acid. The gravity indicates the battery
state of charge at a temperature. The table below shows the state of charge for different gravity
readings:
**Initial gravity readings vary with the battery type and manufacturer.
Contact the battery seller or manufacturer for this information.
For a sealed-top (maintenance-free and recombination) battery, use a high-resolution voltage
battery analyzer.
For any type of battery, use a battery analyzer.
For more information about the type of battery you are charging or how to check the state of
charge, contact the battery seller or manufacturer.
