What are diesel generator batteries?

What kind of battery do I need for my generator?

Generators have become ubiquitous in our everyday life & necessity in every business sector, be it hospitals, banks, offices, remote locations & residential apartments.
Generators require a high cranking current. Microtex DG batteries are capable of multiple cranks in excess of its requirement due to excellent capacity. Manufactured using state-of-the-art machines, with special calcium-tin alloys, it comes with a reliable performance & is maintenance-free.
Available in the complete most popular capacities 12v 90Ah to 12v 200Ah. Microtex is India’s leading Genset battery manufacturer.

A diesel generator needs to be cranked instantly when the power fails. Most generators located remotely have a built-in automatic mains failure & need to be automatically started immediately. The Genset needs a reliable starter battery to provide the high currents required for cranking the diesel engine. Genset batteries are built differently with a special chemical formulation in the active materials to provide for superior cranking currents to provide for a fail safe starting of the diesel engine.

With a Microtex Genset battery, you get:

  • Trouble-free performance
  • Consistent cranking currents
  • Exceeds required number of cranks
  • Excellent reserve capacity
  • Superior sustained cranking current
  • Reduced water topping-up needs
  • Faster charge acceptance with nano-carbons!
  • High power efficiency – recovers from PSoC quickly

Battery Mistakes All Genset Battery Owners Need To Avoid!

Do not mix new batteries with old batteries

Genset Battery reconditioning: often reconditioning an old DG battery can become quite a costly affair if you keep replacing weak 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. 

Genset replacement batteries: It is best to have an expert from the company visit you to have a thorough inspection of the DG 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 additives or desulfation methods

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

Genset Battery Lifespan: The normal mode of failure of Diesel Genset batteries is usually due to grid corrosion if the lead alloys are not designed properly. Desulfators cannot repair corroded grids.
