Battery Charging: Notes

Battery charging is the means by which the battery can be restored to its full voltage potential. A battery is fully-charged when:

  • Micro 420 electrical system tester indicates battery is OK.
  • All of the battery cells are gassing freely during battery charging.
  • Open-circuit voltage of the battery is 12.65 volts or above.
WARNING: Never exceed twenty amperes when charging a cold (-1Β° c [30Β° f] or lower) battery. The battery may arc internally and explode. Personal injury and/or vehicle damage may result.
