Within 14 seconds the voltage had already climbed to 14.13 volts. (Note: I am using the DVM as terminal voltage not the horribly inaccurate elcheapo charger)


Please note that a "healthy" battery will not see a rise in voltage like this one did. The reason for this quick rise is caused by the effects of sulfation.
