Why has the capacity(runtime) of the battery bank decreased?
为什么电池组的容量（运行时间）会减少？
Capacity loss may be due to: Sulfation of the cells. Equalize batteries until all cells have a specific gravity >1.265. Overheating the batteries. Verify that temperature sensors are properly mounted and verify cell temperatures remain below 50°C (120°F) during charging. Over-discharging the battery bank. Capacity of the battery bank may no longer support an increase in load. Aging batteries. Towards end of life, batteries will slowly drop in capacity until only 50% of the capacity is usable. At this point U.S. Battery recommends battery replacement. Consistent undercharging. Verify that your batteries are receiving a full charge using specific gravity readings.
能力损失可能是由于。 电池的硫酸盐化。平衡电池，直到所有电池的比重>1.265。 电池过热。验证温度传感器是否正确安装，并验证充电期间电池温度保持在50°C (120°F)以下。 蓄电池组过度放电。蓄电池组的容量可能不再支持负荷的增加。 老化的电池。在接近使用期限时，电池的容量会慢慢下降，直到只有50%的容量可以使用。在这一点上，U.S. Battery建议更换电池。 持续的充电不足。使用比重读数来验证您的电池是否得到了充分的充电。
