Diagnostic Testing
3-1. TESTING FLOODED LEAD ACID
MAINTENANCE FREE BATTERIES WITH
A HYDROMETER EYE
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
If battery has threaded terminals, use terminal adapters or verify
you are testing on the lead pads not the threaded terminals.
Testing using the studs can create a false bad battery reading.
If you are using an hand held electronic tester, then follow the
instructions provide with the tester.
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 than 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 at 0˚F in amps.
b. After 15 seconds with load on, measure and record battery
terminal voltage.
c. Turn load off.
