Motobatt PDCT1 Tech 1 Charger Customers told us they don’t want to study engineering just to charge a battery. Motobatt responded with the Tech 1 Charger Maintainer. Application: All Powersports and Automotive ride and maintain situations. A highly versatile charger that will charge larger batteries and the correct voltage for AGM, GEL, Calcium, Flooded, LifePo4. Comes with handy Ring Terminal charging harness to connect right to your machine, plug and play. Features 6 volt or 12 volt 6 Step Fully Automatic Charger. Just flick the switch 6 or 12V, don't wonder what all those flashing lights mean. Red stop, yellow working on it, green go. Plug and Leave. Optimized for Motobatt AGM Batteries and Lithium Batteries Motobatt's clever Mosfet Microprocessor reads and constantly controls the correct voltage of the battery connected, the 6 Phase process monitors the battery resistance 100's of times per second during charging mode. Qualification Stage checks the battery is over 2V for safety reasons, and to save power. Then transitions to "Rescue" Phase where an arsenal of different recovery modes can be utilized to revive heavily Sulfated or deeply discharged batteries. Generally at this stage unusually high voltage is seen early in the charge cycle, once the rescue phase is done the battery is ready for the next stage. When the charger detects a low initial state of charge, voltage and current are delivered at a specific rate to assist the battery recovery before entering Pulse charging mode. Recondition Phase Starting from 0.3v Provides a high frequency pulse charge to help the newly recovering battery to accept charge as it enters recondition mode. Continues to work the battery at a slightly higher voltage and amperage to re-activate the battery plates for improved depth of charge. Now that the battery has been eased back to life……. Bulk charge phasecan begin giving constant current to the battery up to about 80% of its capacity. Absorption Phasebegins with constant voltage being supplied while current is reduced. This occurs according to the batteries ability to accept charge up to 100%. Monitors the batteries ability to hold the charge properly, if not it will cycle back through the entire process for 24 hours or more until it determines the battery cannot be recovered. For revived batteries it then enters Auto Stop When the battery is fully charged Maintenance Phase where the battery can stay indefinitely connected to the charger. As the battery drops voltage while unused, the unit will activate when needed to ensure a full state of readiness. Keeping your batteries properly maintained will dramatically Extend working Life.
