1. 1
   Be sure temperature of electrolyte is between 70ºF and 100ºF.
2. 2
   Inspect battery case for cracks or leaks. If case is damaged, replace battery. If case looks OK, go to step 3.
3. 3
   Apply a 300 amp load for 15 seconds to remove surface charge.
4. 4
   Wait 15 seconds, then apply a test load of 280 amps for 15 seconds.
5. 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. 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.
