Temperature Compensation Based on Battery Type

The C-Series controller uses the battery type to determine the temperature compensated voltage settings. The temperature compensated charging voltage is normally based on a Lead – Acid types of battery.

If using Alkaline-type batteries, the R46 resistor on the circuit board inside the controller will have been clipped as shown in “Setting Voltage Parameters for Alkaline Batteries” on page 26. If the R46 resistor is cut, the temperature compensation charging voltage will be based on Alkaline-type batteries.

See the battery type below to determine the temperature compensation value change per temperature or refer to the temperature compensation calculations for a Lead-Acid type battery as show in Table 2-2.

•Lead-Acid Type Batteries:

5 mV per cell per degree Celsius

•Alkaline -Type Batteries (NiCad or NiFe): 2 mV per cell per degree Celsius

Table 2-2describes approximately how much the voltage may vary depending on the temperature of the batteries.

Automatic Battery Temperature Compensation

Temperature compensation can be accomplished automatically by using a Battery Temperature Sensor (BTS). The sensor attaches directly to the side of one of the batteries in the bank and provides precise battery temperature information.

See “Installing the Battery Temperature Sensor” on page 51 for detailed instructions on how and where to install the BTS.

If a BTS is installed, the charge controlling process will be automatically adjusted for the battery temperature. When using a BTS, set the Bulk and Float voltage for a battery at normal room temperature for 77 °F (25 °C).
