Battery Charging

Due to increased positive plate surface area, tubular plates have more electrical capacity than flat plates of comparable size and weight. With positive plate shedding eliminated, tubular batteries also provide up to a 30% longer service life than flat plate batteries. Perhaps most importantly to stationary applications the tubular positive grid does not require horizontal bars, which virtually eliminates positive plate growth and therefore post seal leaks and jar cracking. As a result, in applications which require a long service life, tubular plate batteries provide the best and most reliable power.

MARATHON Solar Flooded MONOBLOC BATTERIES are designed to offer reliable, low-maintenance power for renewable energy applications where frequent deep cycles are required and minimum maintenance is desirable.

Maxxima Batteries are permanently charged and discharged in all applications. These cyclical demands require batteries with special characteristics, which are fulfilled in all respects by the Maxxima solar batteries. They are characterized by high cycle stability, long life, minimum maintenance requirements, very low self-discharge and they are easy to service and mount and have a short charging time. Maxxima solar batteries guarantee the highest level of reliability and efficiency for your solar pv system.

MARATHON has been selling tubular lead-selenium vented batteries for nearly 9 years. The combination of the tubular positive plates and the lead selenium/low antimony alloy provides the best possible combination in lead-acid plate technology.

Marathon batteries are manufactured in accordance with IS 13396 and IS 1651 standards. By utilizing a small amount of selenium in the grid alloy, a dense fine grain structure is produced. This alloy is extremely corrosion-resistant and virtually eliminates inter granular corrosion which is one of the most common causes of cell failure. A lead selenium cell combines the advantages of both lead calcium and lead antimony cells while exhibiting none of the disadvantages.
