Durability as a property batteries shunting locomotives long survive before failure or limit state residual capacity can be quantified by several factors, among which in the first place should be called mean time (working hours) T battery failures. Batteries for shunting locomotives as an indicator of durability

appropriate to apply MTBF, which is the ratio of the total time Tsoumou similar batteries notk amount of their failures. For durability characteristics batteries shunting locomotives should be used indicator "gamma-interest operating time. "For a normal distribution of values starting current batteries shunting locomotives, estimating the parameters a and σ can be obtained with the full terms of the performance test. On the basis of calculations obtained density distribution MTBF

battery shunting locomotives with the standard and modernized system start-up. The findings suggest an increase in battery life by 36%.

Key words: rechargeable battery, battery capacity, reliability, distribution law.
