The sophisticated UNK1 contains a smart charging management system, which monitors battery types, capacities, and initial internal resistance, then automatically applies the most appropriate charging current based on this data. The device also provides battery-condition monitoring, carrying out a health inspection based on resistance at the time of installation.
