Notes: 
1) Termination of Fast Charge on the 4-stage Fast Chargers is done primarily by using (1) dynamic inflection point voltage slope detection (negative 1st derivative of dV/dt) and also, if "Option" for thermistor detection in the charger is chosen, then fast charge is also terminated  by using (2) excessive temperature slope detection (rate of change in battery temperature) determined by measuring the rate of change in resistance of the thermistor. Safety backups to the primary fast charge termination method above include:
                       a)  "Negative delta V" and "peak voltage (or zero delta V)" detection and
                       b)  Timer controlled fast charge termination.
                       c)  Termination if the set point for "maximum allowable battery temperature" is exceeded (Only if "Option" for thermistor detection in the charger is chosen).
2)  The battery AH rating divided by the charge current for the respective model will determine the selection of the "C rate" for the model to be ordered. Charge rates of 4C, 2C, 1.3C, C/1, C/1.5, C/2, C/2.5, C/3, C/4, C/5, C/6, C/7, C/8, and C/9 are "standard rates" available.  Custom "C rates", up to C/9,  also available for large quantity applications.  Call for technical support when in question.

Notes: 
1) Termination of Fast Charge on the 4-stage Fast Chargers is done primarily by using (1) dynamic inflection point voltage slope detection (negative 1st derivative of dV/dt) and also by using (2) excessive temperature slope detection (rate of change in battery temperature) determined by measuring the rate of change in resistance of the thermistor. Safety backups to the primary fast charge termination method above include:
                       a)  "Negative delta V" and "peak voltage (or zero delta V)" detection and
                       b)  Timer controlled fast charge termination.
                       c)  Termination if the set point for "maximum allowable battery temperature" is exceeded.
2)   The battery AH rating divided by the charge current for the respective model will determine the selection of the "C rate" for the model to be ordered. Charge rates of 4C, 2C, 1.3C, C/1, C/1.5, C/2, C/2.5, C/3, C/4, C/5, C/6, C/7, C/8, and C/9 are "standard rates" available.  Custom "C rates", up to C/9,  also available for large quantity applications.  Call for technical support when in question.

Notes: 
1) Termination of Fast Charge on the 4-stage Fast Chargers is done primarily by using (1) dynamic inflection point voltage slope detection (negative 1st derivative of dV/dt) and also by using (2) excessive temperature slope detection (rate of change in battery temperature) determined by measuring the rate of change in resistance of the thermistor. Safety backups to the primary fast charge termination method above include:
                       a)  "Negative delta V" and "peak voltage (or zero delta V)" detection and
                       b)  Timer controlled fast charge termination.
                       c)  Termination if the set point for "maximum allowable battery temperature" is exceeded.
2)   The battery AH rating divided by the charge current for the respective model will determine the selection of the "C rate" for the model to be ordered. Charge rates of 4C, 2C, 1.3C, C/1, C/1.5, C/2, C/2.5, C/3, C/4, C/5, C/6, C/7, C/8, and C/9 are "standard rates" available.  Custom "C rates", up to C/9,  also available for large quantity applications.  Call for technical support when in question.

Models with 4-Stage Pulse Charge, Multiple Methods of Charge Termination (See Note 1 under table), and with IEC 320 input connector and Anderson Power Pole output connector on charger unit for connection of the customer furnished output power cable with mating connector, and with separate DIN connector for connecting a customer-furnished 2-wire cable with mating connector and with an isolated thermistor in a ring tongue barrel on the end for connection to one of the (+) battery posts (which is close to the internal battery temperature).   (See Note 3 below for "Accessory Items"). 

Note:  These charger models can also be used with NiCd battery systems if customer wants to use a thermistor temperature sensor for protection when charging NiCd batteries.

Knowing your battery's "number of cells and AH rating", look in the 5th column of table below for the AH rating to determine the "Charger Series and a model (charge rate,C)" that will be suitable for your battery and your application!
