Microtex diesel locomotive starter battery - approved by Indian Railways


Microtex regularly export diesel locomotive engine starter batteries

Diesel locomotive engines use heavy duty industrial diesel locomotive engine starter batteries for starting and operation of a variety of on-board equipment. 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 diesel loco starter batteries as per customer need of railway diesel locomotive engine starter battery with RDSO approved specifications.

Innovative Design

  • Sturdy container design for durability
  • Designer lead alloys with low antimony for tubular positive plates & negative plates to prevent failures due to corrosion 
  • Special Low Antimony alloys makes for less water topping up requirements & reduces the need to top up more frequently
  • Correctly Balanced Active Materials ensure long life & trouble free performance
  • 150 bar High Pressure Die casted Spine Grids for Tubular Positive Plates (densely compacted under such high pressures prevent early corrosion failures)
  • Superior Woven Tubular Gauntlets (not NON Wovens) for Tubular plates Woven tubular gauntlets will not rupture in service and  active material will not leak causing internal shorts & failure
  • Specially designed Vent Plugs with high visual Red Float level indicator offers easy visual indication of electrolyte level
  • High quality flexible copper cell connectors with accurate current rating design
  • Special lead coated, corrosion resistant bolts
  • Plastic shrouds on connectors ensure no accidental shorts
  • Prefer Factory Charged Batteries – No fuss no mess. Use straight away

Caring for your diesel locomotive starter battery

  • Overcharging damages cells: Try to use automatic chargers that switch off once the battery reaches its maximum charge
  • If you don’t possess an auto-charger, set a charge time via alarm clock or other means to check the charging progression in incremental periods
  • Check water levels each month: Level checks are particularly easy with Microtex batteries, as the vent plugs are fitted with visual indicator floats marked red & green
  • Always use demineralized water
  • Regularly check for corrosion: Our battery terminals are coated for anti-corrosion properties, though, from time to time it may be necessary to clean the terminals 
  • Take preventative measures: A thin layer of petroleum jelly will protect your battery terminal from corrosion

Dictating best practices for those who maintain diesel Locomotive engine starter battery are one thing, implementing them are another.

Please provide us with the following information to ensure that you receive the right battery for years of great performance:

  • What is the voltage & AH capacity of the Battery
  • Material of the Container-PPCP in FRP Tray or Molded Hard Rubber (HR)
  • Specification conforming to RDSO Spec, DLW Spec or IS Spec
  • Number of Batteries per system/Bank
  • Are maintenance tool kit required? if so please specify the tools required 
  • Are the batteries required in dry uncharged or factory charged condition (Prefer factory charging for long life)

Microtex Diesel Locomotive Engine Starter Battery
keeps your locomotive going!

Specially designed and engineered for the railway industry, the Microtex diesel Locomotive engine starter battery feature higher cranking currents and a higher reserve capacity to augment the auxiliary on-board equipment on the diesel locomotive, making it the choice of the Indian Railways. The cells are constructed to form 8 volt monoblocks. Each 2v Battery is hermetically heat sealed and housed in a Fibre Reinforced Plastic tray designed specifically to avoid any leakage of electrolyte. Electrolyte leakage causes costly corrosion buildup and leakage currents which could damage the electronics in the modern diesel locomotive. The foolproof design ensures the diesel Locomotive engine starter battery performs without any leakage throughout its service life.


The balanced active materials in the woven gauntlet positive tubular plate design and construction ensure higher capacity in the same space. Built to perform in the stringent requirements of the locomotives, these locomotive starter batteries have been serving the Indian railways since 1994 and are the trusted choice of the railways.

Special designer lead alloys, comprising of very low antimony selenium lead with special grain refiners added, to provide minimum water consumption, ensuring reduced water topping up frequency and making it easier to maintain. The woven engineered gauntlets, with precise porosity, do not rupture or burst in service and are superior to the non-woven gauntlets. The terminals are provided with tin-plated electrolytic grade copper inserts to eliminate terminal melting and provide better electrical conductivity minimising internal electrical resistance.

Exporting Batteries to 27 countries since 1977!

Lead acid battery or lithium ion?

The perception in the public domain is that lead acid batteries are old technology. Lithium ion batteries has a different perception, it is modern, cleaner, it has 3 or 4 times the energy density and a longer cycle life. With all of this, what possible advantages could the 150-year old lead acid technology bring to the table?
