LOG Diesel is the battery of choice for use in diesel-powered trucks, buses and tractors because it meets the strictest specifications for these categories. It offers the best resistance to the intense vibration that takes place in long work journeys, which are very frequent in the professional transportation of cargo and passengers. Similar strength is also demanded from batteries used in farming and civil construction operations. The shielded elements technology is the great breakthrough of the LOG Diesel batteries. During the assembly, the elements are submitted to a high compression ratio, in order to attach them to their cavities in the housing. Therefore, the set is capable of avoiding the active material disintegration, even when the battery is exposed to strong mechanical vibration. Tested and approved by the largest truck producers supplied by Moura in South America, the LOG Diesel battery is totally maintenance-free, thus eliminating the need for water replacement and also the risk of the penetration of impurities into the electrolyte
