The MT-iQ-DUO is specifically designed for use in caravans. It prevents the build-up of harmful sulphate deposits and keeps the battery in shape with various programme intervals. Depending on the operating state (driving state/charging mode or idle time), interval boosts are applied according to precisely recorded characteristics. Switchable to battery type (starter or RV, acid, gel or AGM) and its respective capacity. Accessory (not included): remote control. Please order separately.
