3-1. TESTING FREEDOM BATTERIES
CAUTION
When handling batteries, wear face or eye
protection and provide good ventilation.
Have a water supply available and keep
away from fire, flame or sparks.
3-2. TEST PROCEDURE.
Disconnect
NOTICE
If battery has threaded terminals,
use
terminal adapters, AC-Delco No. ST-1201, on
each terminal when testing or charging.
Inspect
1. Each battery visually for damage.
2. Battery hydrometer eye.
• If battery has no hydrometer eye, proceed
to step 3.
• Eye shows green, proceed to step 3.
• Eye shows dark, recharge battery then
proceed to step 3.
• Eye shows yellow, replace battery.
3. Apply 300 amp load to battery for 15 seconds
and turn off load. Wait one minute.
4. If battery has no hydrometer eye, measure
terminal voltage:
Test
a. If 12.4 volts or more, continue test.
b. If less that 12.4 volts, recharge battery
and repeat steps 3 and 4.
Test
5. All batteries passing previous inspection or
test, as follows:
a. Apply test load of 1\2 CCA rating @ 0˚F
in amps.
b. After 15 seconds with load on, measure
and record battery terminal voltage.
c. Turn load off.
d. Estimate battery temperature and check
recorded voltage against following table.
Temp. ˚F

e. If recorded voltage does not meet or exceed
that in table, replace battery. Otherwise
battery is OK.
3-3. TEST COMPLETION.
Clean
1. Cable ends and battery terminals with wire
brush.
Tighten
1. Battery hold-downs to specifications.
NOTICE
Leave battery cables disconnected and
proceed with wiring tests.
3-4. TESTING CONVENTIONAL BAT-
TERIES
CAUTION
When handling batteries, wear face or eye
protection and provide good ventilation.
Have a water supply available and keep
away from fire, flame or sparks.
