Where specialist battery types require charging Voltage parameters to be other than the factory default settings these can be programmed at the Marlec factory or by using the Marlec Interface Cable and Rutland 1200 Settings Adjustment App. We recommend that users consult with their battery supplier or manufacturer to provide the following information for reprogramming. Marlec does not assume any responsibility for the suitability of the customer provided specifications for the operation, condition or lifetime effects on batteries.
