Dual/single outputs booster charger 2.4 TBB Premium II five stages charging algorithm Fitted with five stages charging algorithm (soft start-bulk-absorption-float-recycle), DMT1250/DM1230 is able to charge auxiliary battery quickly and fully. Microprocessor controlled charging algorithm with variable absorption charging timer to guarantee the optimal charging for batteries of different discharged states. -
Page 11: Back-Charging Function
Dual/single outputs booster charger 2.6 Back-charging function It’s required to connect D+ cable or ACC signal to enable back-charging function. All standard models comes with back-charging function, which allows DMT/DM draws power from auxiliary battery to charge starter battery (charge current is from 0-3A). With back-charging function, it will prevent starter battery to get flat which fails to start engine. -

Dual/single outputs booster charger 4.5 Mounting holes Find a appropriate mounting surface, drill mounting holes as dimension shown in below picture. Figure 4-2 Drill holes for mounting Please have the charger installed with auxiliary battery as close as possible to reduce voltage drop on cable. - Page 19 Dual/single outputs booster charger The voltage of auxiliary battery must be above 2V if the battery type isn't lithium type, or the charger will not charge to auxiliary battery. If the auxiliary battery is lithium type and the voltage is below 2V , the charger works on 'wake up' mode with a constant voltage output until the output current over 3A and then the charger turns into the battery charging mode.
