I'm getting code E112, I REMOVED VEHICLE MGR. AND CLEANED, WORKED GOOD FOR A FEW DAYS NOW SHUTS DOWN AGAIN. ALSO LIFT CAME INTO SHOP LOW VOLTAGE. BATTERY TESTED BAD. INSTALLED 4 NEW GEL CELL BATTERIES. THE CHARGER THE CUSTOMER HAS FOR THIS LIFT IS MADE FOR WET CELL BATTERIES. WILL THIS CREATE A PROBLEM, WILL IT CHARGE TOO MANY AMPS? WILL CREATE OTHER ISSUES? PLEASE ADVISE. LIFT PERIODICALLY DRIVES THEN SHUTS DOWN.
