Blue Smart IP67 12V / 7A charger Fully encapsulated, water, shock and fire resistant! Water, oil or dust will not damage the Blue Smart IP67 charger. The case is made of cast aluminium and the electronics are moulded with resin. An unprecedented level of efficiency! A new industry standard has been set: with an efficiency of 92% or more, these chargers produce three to four times less heat. And once the battery is fully charged, energy consumption is reduced to less than one Watt, nearly five to ten times better than industry standards! 5-stage adaptive charging algorithm: Bulk - Absorption - Refurbishment - Float - Storage The Blue Smart charger features a microprocessor-controlled "adaptive" charge management system. The "adaptive" function automatically optimises the charging process according to how the battery is used.
