When a charge is initiated, why does the voltage of the battery bank rise very quickly and transition into the absorption charge cycle or shuts off charge completely?
当开始充电时，为什么电池组的电压会迅速上升，并过渡到吸收充电周期或完全关闭充电？
If the batteries are not already fully charged, this can be an indication of sulfated batteries which may be causing a higher-than-normal internal resistance. Capacity of the bank will be reduced and can be confirmed by running a load test. An increase in bulk charge voltage and/or absorption time may be necessary to de-sulfate the battery bank. Increase bulk/absorption charge voltage in 0.05 volt per cell increments or increase absorption time in 15 – 30 minute increments as necessary. If the battery bank is heavily sulfated, an equalization may be necessary. Perform an equalization charge if specific gravity readings are <1.250 or vary by more than 0.015 volts between cells. Sulfated batteries may heat up more than usual. Follow the guidelines for controlling maximum charging temperatures.
如果电池还没有充满电，这可能是电池硫酸盐化的迹象，可能会导致内部电阻高于正常值。蓄电池组的容量将减少，可以通过进行负载测试来确认。 可能需要增加批量充电电压和/或吸收时间，以便对电池组进行脱硫。根据需要，以每节电池0.05伏的增量增加批量充电电压，或以15-30分钟的增量增加吸收时间。 If the battery bank is heavily sulfated, an equalization may be necessary. Perform an equalization charge if specific gravity readings are <1.250 or vary by more than 0.015 volts between cells. 硫酸化的电池可能比平时更热。遵循控制最大充电温度的准则。
