Battery Test
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 either a JCI or Bear ARBST 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 indicator EYE.
• If the EYE indicates the battery is charged, go to
step 4.
• If the EYE 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 volts, the battery is OK.
• If voltage is below 9.6 volts, go to step 7.
7. Charge the battery on High (40 amps) until the EYE
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 EYE indicates the battery is charged within
three hours, the battery is OK.
• If the EYE indicates the battery is not charged
within three hours, replace the battery.
