Boost charging of the battery
Special tools
Battery charger - with an output of 60A.
Charge procedure
Boost charge the battery as follows :
1. Remove the battery from the machine. Refer to
battery removal.
2. Remove the vent manifolds from the battery.
3. Connect the battery charger to the battery. Make
sure the polarity of the connections is correct and
connect the (+) positive cable first.
4. Set the battery charger to ON.
5. Limit the battery charge to the minimum period
required for the battery to start the engine.
6. Set the battery charger to OFF. Disconnect the
cables from the battery. Make sure you
disconnect the (+) positive cable first.
7. Install the vent manifolds on the battery.
8.Install the battery.
CAUTION :
Boost charging is not
recommended. Boost charging may be
carried out but the current must be limited to
60A.
CAUTION :
Parallel charging is not
recommended, therefore on machines fitted
with twin batteries, charge each one
individually.
WARNING :
Check the battery temperature
frequently as the high charging current can
cause a rapid rise in temperature. Stop the
charging process if the temperature reaches
60
°
C (140
°
F).
Load testing of the battery
Test equipment
Current controlled, high rate discharge tester - with at
least 500A capacity.
Digital voltmeter
Load test the battery as fommows :
1. Remove the battery from the machine. Refer to
battery removal.
2. Set the appropriate current on the discharge
tester :
CURRENT FOR SINGLE BATTERY .......... 295A
CURRENT FOR TWIN BATTERY .............. 410A
3. Connect the voltmeter across the battery
terminals.
4. Apply the load tester across the battery terminals
for 15 seconds and note the voltage during the
test.
Above 10V and steady .....battery is serviceable
Above 10V but failling rapidly.....replace battery
Below 10V ................................. replace battery
