What are Diesel Locomotive batteries?

Why locomotives are diesel electric?

The  modern diesel locomotive in India is a self-contained version of the electric locomotive. Like the  electric locomotive in Indian Railways,  it has electric drive, in the form of traction motors driving the axles and controlled with electronics. For over five decades, Microtex has been a technological leader in the development of high-performance industrial lead-acid batteries, especially for Indian Railways.  Microtex continues its commitment to research and development for improving the diesel locomotive starting battery as per customer needs of railway diesel locomotive engine starter battery with RDSO approved specifications.

How many volts is a locomotive?

Battery Mistakes All Diesel Locomotive battery Owners Need To Avoid!

Do not mix new batteries with old batteries

Railway Diesel Locomotive Battery reconditioning: often reconditioning an old locomotive battery can become quite a costly affair if you keep replacing dead batteries one by one; even the new battery will drain out rapidly as the old batteries tend to draw more out of the new one. 

Diesel Locomotive replacement batteries: It is best to have an expert from the company visit you to have a thorough inspection of the Diesel Locomotive batteries after a complete charge, compare the cell voltage, specific gravity to decide the state of charge & whether in needs to be replaced at all.

Avoid any sort of battery additives or desulfation methods

How to recondition Diesel Locomotive batteries? Diesel Locomotive Batteries are electro-chemical devices. All chemicals have a half-life period beyond which regeneration with chemical battery additives or desulfators for batteries have little effect, if any, temporary. 

The normal mode of failure at end of life of Diesel Locomotive batteries are usually due to the decomposition of the positive plate and or grid corrosion. Desulfators cannot repair corroded grids. Once the positive plate decomposes, there is no magic or chemical in the world that will rejuvenate the battery. CdSO4 has been used, to give the battery a shot of adrenaline, but is highly toxic & causes problems in the recycling stream.
