苏联2ТЭ10Л型内燃机车从1978年起开始采用4KMЛ—19Д型蓄电池组。这种蓄电池组在使用过程中其壳体经常出现裂缝,导致电解液泄漏,最终使其报废。苏联阿什赫巴特机务段对这种蓄电池组进行了修复。蓄电池壳体的裂纹和小的脱块先用刮刀或锉刀修整,然后用沾有丙酮的刷子对修整好的部分进行脱脂处理并涂上一种专用涂料。涂上去的涂料应与蓄电池组壳体平齐。然后在涂料上铺上一层玻璃布,并让它在室温下
The Soviet Union 2ТЭ10Л diesel locomotive since 1978, the use of 4KMЛ-19Д-type battery pack. This battery pack in the course of its housing often cracks, resulting in electrolyte leakage, eventually scrapped. This battery pack was repaired by the Soviet Union Ashgabat Depot.
