Bottle repair technology: The battery is first charged in history

The procedures for the first-time charging of the battery in history are as follows: First, according to the provisions of the battery manufacturer, the electrolyte of a certain density is fed, and stand for 3 to 6 h, and the liquid level height is adjusted to the upper edge of the high plate is 10 to 15 mm. The electrolyte temperature should be reduced to 35 ° C before accessing the charging power source. Battery initial charging should be selected for two-stage constant current charging method. The first stage charging current is 1/15 of the battery rated capacity. When the air bubble is generated in the electrolyte, when the single-handed voltage reaches 2.4V, the charging current is reduced, both second stage. Continue to charge to the electrolyte vigorously discharge bubbles (boiling), the electrolyte density and the voltage are stable for 3 hours. All charging time is about 60 ~ 70h, and the initial charging is characterized by small charging current, long charging time, and adequate electrochemical reaction. The electrolytic solution temperature should be detected during the charging process. When the temperature rises to 40 ° C, the charging current should be reduced. If the temperature continues to rise to 45 ° C, the charging should be stopped, and the charge should be stopped to 35 ° C. When charging is approaching, the electrolyte density should be measured, such as the electrolyte or distilled water having a density of 1.4, and then charge 2 h, until the density meets the specification. The second charging is actually overcharged and charged. As for the charging time, different battery requirements are different, please follow the instructions.
