The charge program constantly monitors the battery's voltage, and limits the current in order to prevent excessive gassing of the battery. The 1220 now charges the battery using the maximum possible current until its voltage rises to around 2.3 to 2.35 Volts per cell. The charger then switches to a lower current to bring the battery gently up to full charge;... -
