A revolutionary advancement in multiple battery charging, PulseTech's SC-12 (746X810) Pallet Recovery Charger features 12 independent 6A (max) charging channels secured inside an HPX plastic roll-around cabinet (the suitcase charger). Working with any type of battery, including flooded, AGM or GEL, this state-of-the-art charger actually interrogates the battery and profiles it prior to beginning the pulse charge/conditioning sequence. The key to successful recovery and proper charging of batteries, including heavily discharged and sulfated batteries, is the one-two punch provided by the application of our patented high frequency pulse and the correct charge current provided by our exclusive algorithms. It doesn't matter what type of batteries you may have or the size of each of the 12 batteries attached because the SC-12 Charger deals with each battery individually. --Robert White, Vice President of Sales for PulseTech-- The sturdy, sealed mobile unit weighs 48 pounds (without cables) and 57 pounds (complete). Safe to use, the SC-12 is reverse polarity protected and is spark protected. A 25' extension cable is also available as needed.
