Lento SMF batteries differ from traditional gel based SMF batteries in that the same charging system without modification of current or voltage can be used as one uses for charging flooded batteries. At the heart of Lento SMF technology is the use of special grade fine fiber high density glass mats with a high degree of porosity. These glass mats are sandwiched between the positive and negative plates and hold a higher amount of acid electrolyte firmly held between the fibers.
