Battery: Testing and Inspection
Battery Test
WARNING: A battery can explode if you do not follow the proper procedure, causing serious injury to anyone nearby. Follow all procedures
carefully, and keep sparks and open flames away from the battery.
Use an ED-18 (TM) Battery Tester, and follow the manufacturer's procedures. If you don't have one of these computerized testers, follow this
conventional test procedure:
1. Be sure the temperature of the electrolyte is between 70° F (21° C) and 100° F (38° C).
2. Inspect the battery case for cracks or leaks.
-
If the case is damaged, replace the battery.
-
If the case looks OK, go to step 3.
3. Check the test indicator window.
-
If the test indicator window indicates the battery is charged, go to step 4.
-
If the test indicator window indicates a low charge, go to step 7.
4. Apply a 300 amp load for 15 seconds to remove the surface charge.
5. Wait 15 seconds, then apply a test load of 280 amps for 15 seconds.
6. Record battery voltage.
-
If voltage is above 9.6 V, the battery is OK.
-
If voltage is below 9.6 V, go to step 7.
7. Charge the battery on High (40 amps) until the test indicator window shows the battery is charged, plus an additional 30 minutes. If the battery
charge is very low, it may be necessary to bypass the charger's polarity protection circuitry.
-
If the test indicator window indicates the battery is charged within three hours, repeat steps 4 through 6. If the battery is still below 9.6 V,
replace the battery.
-
If the test indicator window indicates the battery is not charged within three hours, replace the battery.
