Selecting a Battery Type When Setting up the VSM 422

January, 20 2009

The VSM 422 uses battery type information to accurately compute State of Charge. To obtain the greatest precision when measuring State of Charge, input your battery type into the VSM 422 when performing initial setup or changing battery types.

The following table will help you determine your battery type:

Although choosing the wrong battery type will not result in large errors in State of Charge measurement, this information helps the VSM 422 select an open circuit voltage curve and self-discharge attributes characteristic of a particular battery style. Entering the correct battery type will result in optimal accuracy of the VSM 422’s State of Charge monitoring.
