Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
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:
- The Midtronics (special tool #GR8-1220KIT-CHRY, AGM Battery Tester/Charger Station) tester indicates battery is GOOD.
- All of the battery cells are gassing freely during battery charging.
- An Open-circuit voltage of the battery is 12.65 volts or above.
Never exceed twenty amperes when charging a cold (-1° C [30° F] or lower) battery. The battery may arc internally and explode. Personal injury or vehicle damage may result.
