1. |
Be sure temperature of electrolyte
is between 70ºF and 100ºF. |
2. |
Inspect battery case for cracks or
leaks. If case is damaged, replace battery. If case looks OK, go
to step 3. |
3. |
Apply a 300 amp load for 15 seconds
to remove surface charge. |
4. |
Wait 15 seconds, then apply a test
load of 280 amps for 15 seconds. |
5. |
Record battery voltage. If voltage
is above 9.6 volts, battery is OK. If voltage is below 9.6 volts,
go to step 7. |
6. |
Charge battery on High (40 amps) until
battery is charged, plus an additional 30 minutes. If battery charge
is very low, it may be required to bypass charger's polarity protection
circuitry. If battery is charged within three hours, battery is
OK. If battery is not charged within three hours, replace battery. |
