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 an ED-18 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 3 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 3 hours, replace the
battery.
