Pentalift now offers an auto charging feature that is available for its popular SolarDock series of solar powered dock levelers. The auto charge system automatically senses the charge status of the battery and, if required, automatically turns on the AC charger to replenish the charge in the battery, then automatically turns off the AC charger and then reverts back to the solar cell charging system. This feature eliminates the requirement to monitor the charge status of the battery and manually select the AC charge circuit in the event the battery charge level is low.
