XSTATIC HAS RELEASED AN ALL NEW 5 STAGE BATTERY CHARGER THAT IS TOTALLY AUTOMATIC. XSTATIC OFFERS THREE MODELS TO CHOOSE FROM:   12 VOLT 14/16 VOLT 36 VOLT THESE FIVE STAGE MICROPROCESSOR CONTROLLED BATTERY CHARGERS WILL CHARGE A BATTERY TO 100%.  OTHER CHARGERS CAN ONLY CHARGE TO 60% CAUSING BATTERIES TO FAIL PREMATURELY. RETAIL PRICE IS $369.00 FIVE STAGE MICROPROCESSOR BASED   FEATURES ALL 5-L.E.D. DISPLAY Eliminates guessing the battery's condition or State Of Charge by displaying State Of Charge .  If a charging error should occur, the Charge Error Condition is displayed using 3 of the 5 L.E.D.'s.  An Ammeter displays real time charging current information.   LARGE PROTECTION Reverse battery, sort circuit, input overload, output overload, and over temperature protection are standard features.  Programmed safety features include the “Charge Time Monitor”, which safely shuts down charging, if charge time is exceeded and Thermal Runaway Detection (a common occurrence when cells age and fail) terminates further charging.                          CHARGE                        CHARGE ALGORITHM                 True Microprocessor control, programmed with a proprietary software, applies an I-E-I charge algorithm.  Charges at a Constant Current rate until battery voltage reaches the Constant Voltage Mode.  Then regulates voltage until battery has reached 100% charge, where it transitions to Float Mode.  It remains in Float Mode until the 28 Day Recycle elapses, or returns to Constant Current Charging if batteries have been loaded down by a load.   PRE-QUALIFICATION TEST         Tests for shorted cells, sulfated battery, wrong battery types and high internal battery resistance before fast charging begins.   SLOW (SOFT) START                     Gently ramps up to the required output charge level which avoids “bashing” the battery   MINIMAL LOADING                     Disconnected from A.C. power, but with output leads left connected to battery, battery drain is much less than 1mA.   STANDARD PACKAGING             Dimensions, 6.75 Wide by 5.88 Tall by 10.0 Long.  One unit per carton, shipping weight:  32 pounds.
