What if the battery cases are bulging on the sides?
如果电池盒侧面隆起怎么办？
As batteries age, some bulging of the side and end walls caused by growth of internal components is normal. Due to the weight of electrolyte, some case bulging is normal with new batteries. Excessive bulging may be the result of operation at higher than recommended temperatures (>120ºF or 49ºC) or from prolonged undercharge causing excessive sulfation. This can cause permanent loss of capacity and shorten battery life. Severe bulging may be an indication that the batteries have been frozen. Freezing can do permanent damage to the internal components in batteries and could result in an exploded battery. Batteries that are frozen or have been frozen should not be used.
随着电池的老化，由于内部元件的增长，侧壁和端壁出现一些鼓包是正常的。 由于电解液的重量，新电池出现一些外壳鼓起是正常的。 过度隆起可能是在高于推荐温度（>120ºF或49ºC）下操作的结果，或者是由于长期充电不足导致过度硫化。这可能会导致容量的永久性损失，并缩短电池寿命。 严重的鼓包可能表明电池已经被冻结。冻结会对电池的内部元件造成永久性损害，并可能导致电池爆炸。被冻结或已经被冻结的电池不应使用。
