GS YU-FIT Configuration Tool

Battery configuration for smart charge technology and ISS systems made easy with GS YU-FIT.

An increasing number of automotive manufacturers have introduced systems that now require replacement batteries to be correctly configured to the vehicle after installation.

With the introduction of new CO2 production control systems such as smart charging and Idle Start/Stop (ISS) it is essential that the vehicle has the correct battery type and specification installed.

Failure to configure the correct specification battery could result in:

  • Undercharging or overcharging of the battery, resulting in damage which is not covered by the manufacturer’s warranty
  • Loss of the ISS CO2 production control system functionality
  • Possible loss of non-critical vehicle system functions

The configuration process therefore:

  • Informs the vehicle that a new battery has been installed
  • Informs the charging system of the new battery characteristics
  • Ensures the vehicle uses the correct charging parameters for the new battery
