The battery is positive to the positive electrode, and the battery negative electrode is negative.
At the beginning of the primary charge, it is carried out in two stages: first charge the electrolyte by the initial charging current to discharge the bubble, and the single voltage rises to 2.3 to 2.4V. The current drops the current to 1/2 initial charging current, and continues to be filled into the electrolyte to release dramatic bubbles, compact and voltage continuous 3 h stability. All charging time is approximately 45 to 65 h.
When the charging process, the electrolyte temperature is often measured by the electrolyte temperature, stop charging or cooling, and the temperature is controlled at 35 ~ 40 ¡ã C, and when the primary charge is completed, if the electrolyte is not suited, the electrolysis of the distilled water or the specific gravity of 1.4 is applied. The liquid is adjusted. After adjustment, charge 2h until the proportion meets the specified.
After the new battery is first charged, the capacity is often not reached, and the discharge cycle should be performed. The discharge rate is discharged at 20HH (i.e., the current discharge of the rated capacity is 1/20 is discharged to the single voltage drop to 1.75V), and then the charge current is sufficient, after a charge, the discharge cycle is still lower than the rated capacity 90 %, You should make a charge, discharge cycle
