Have a water supply available, and keep away from fire, flame or sparks. 3-2. TEST PROCEDURE. Disconnect NOTE 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. NOTE 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. d. Estimate battery temperature and check recorded voltage against following table. Temp. 0F 70 50 30 15 0 Min. Volts 9.6 9.4 9.1 8.8 8.5 e. If recorded voltage does not meet or exceed that in table, replace battery. Otherwise, battery is okay. 3-3. TEST COMPLETION. Clean 1.
