Our restoration technology is backed up by years of research and development (R&D), together with the satisfaction showed by our clients, who consider it to be:

“an efficient system which our technicians are extremely familiar with and a high-performance tool which allows us to extend the life and capacity of the batteries of our fleet”

There are several reasons which make the real service life of the battery be shorter than the estimated lifespan. Among them, and to a great extent, the generation and build-up of lead sulphate and its subsequent crystalline structure; but also, the reduction in the electrolytes caused by electrolysis, the corrosion or short-circuits of the electrodes, and the loss of active materials.

Maroo MCS restoration equipment acts on the battery by using electrical properties in order to reverse its degradation, which is basically due to the build-up of sulphate on the electrodes.

Our restoration technology is based on the rectification of the alternating wave and the generation of pulses at twice the frequency with an angle determined and calibrated by the software. The result is the crazing of lead sulphate crystals and their conversion, again, into active material; what leads to the recovery of a great deal of its capacity.

A battery can be restored by removing the lead sulphate, thus achieving a significant financial saving:

  • With regard to the replacement of batteries, by extending their initial service life.
  • With regard to maintenance costs, by showing a more homogeneous and accurate performance.
  • With regard to the repair of the equipment, by reducing technical problems.
  • With regard to the expenditure on materials, by reducing the replacement of the components.
  • With regard to labour costs, by achieving maximum productivity in all aspects.
  • With regard to waste treatment, by significantly reducing the amount of waste.
  • With regard to energy costs, by decreasing charge times and reducing their number.

It is possible to carry out two different types of restoration processes:

RECOVERY RESTORATIONpractical advantage

It is the best option when dealing with old batteries which are operating below their optimum level and whose necessary level of performance is not being achieved due to their high degree of sulphation.


This option can also be applied to bring back to life those batteries which have not being used for a while and have lost part of their charge capacity.


This graph shows the recovery of the capacity and, consequently, the durability of a battery after being subjected to a recovery restored battery.




Through a maintenance programme which carries out restorations on a regular basis (e.g.: one year), it is possible not only to double or, in some cases, even triple the service life of the batteries, but also to constantly keep them at a high level of performance.


With regard to new batteries, a maintenance schedule suitable to their duty cycles is strongly recommended. By following this schedule, you will obtain a faster charge, less electricity consumption, and less number of replacements.
