Why are the specific gravity readings at full charge varying significantly, (>0.015)?
为什么充满电时的比重读数变化很大，（>0.015）？
This may be caused by multiple parallel strings of batteries in a bank, which often result in charge imbalance. U.S. Battery does not recommended that a system exceed 3 strings of batteries connected in parallel. Charge voltage may be too low. Verify they meet U.S. Battery recommended charging parameters for Flooded batteries. An increase in Absorption charge time may be necessary. Increase in 15 to 30 minute increments as necessary. If specific gravity readings vary by >0.050 points then it is safe to assume the battery has a bad cell. Charge Current = C/10 Amperes Charge Voltage = 2.583 Volts per Cell Charge Time = 10 Hours Battery temperature adjustment: reduce the voltage by 0.028 Volts per Cell for every 10 degrees (F) above 80 degrees (F), increase by the same amount for temperatures below 80 degrees (F).

这可能是由于一个电池组中的多组并联电池造成的，这往往会导致电荷不平衡。美国电池公司不建议一个系统超过3组并联的电池。 充电电压可能太低。验证它们是否符合美国电池公司推荐的充水电池的充电参数。 可能需要增加吸收充电时间。必要时以15至30分钟为单位增加。 如果比重读数变化>0.050点，那么可以认为电池有一个坏电池。 充电电流=C/10安培 充电电压=每单元2.583伏 充电时间=10小时 电池温度调整：温度高于80度（华氏）时，每格电压降低0.028伏，温度低于80度（华氏）时，每格电压增加相同的量。 下载完整详细的充电说明
