Charge on High Setting (40 amps)
Charge until EYE shows charge is OK, plus an additional 30 minutes to
assure Jull charge.
NOTE: lf the battery charge is very low, it may be necessary to bypass
the charger's polarity protection circuitry.
lf the EYE does not show charge is OK within three hours, the battery is
no-good; replace it. Write down how long the battery was charged.
Test Load Capacity (#2)
. Apply 300 amp load for 15 seconds to remove surface charge.
. Allow 15 Seconds recovery period,
. Apply test load (see Test Load Chart).
. Record voltage at the end ot 15 seconds.
Voltage drops below 9.6 volts;
battery is no-good,Voltage stays above 9.6 volts;
battery is OK.
TEST LOAD CHART
Use the test load or use 1/2 the cold cranking amps (CCA) printed on
the label on the top of the battery. lf neither is indicated. use the infor-
