Page 35: Battery Charge Procedure
PORTAFLOW 300 Battery Charge circuit Operation. Charging Controller IC: A Maxim IC MAX712 or MAX713 controls the Ni-Cd and Ni-Mh battery charger. It has two modes, fast charge and trickle charge; an output indicates the fast-charge status. In both modes it supplies, via a PNP power transistor, a constant current to the battery, by keeping a constant voltage across a current sensing resistor. - Page 36 The fastest way to fully charge the battery is to charge for 4.5 hrs, then switch the power supply off and on again, thus re-starting the fast charge for another 4.5 hr period, followed by trickle charge. Warning: If the battery is getting warm, that would indicate that it is full, and the power supply should not be connected again - overcharging reduces the life of the battery.
