YU-FIT USER GUIDE
Introduction
With the introduction of new CO2production 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.
An increasing number of automotive manufacturers have introduced systems that now require a
replacement battery to be correctly configured to the vehicle after installation.
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 CO2production control system functionality
• Possible loss of non-critical vehicle system functions
Battery configuration prevents incorrect battery charging, ensures the correct operation of the
ISS
CO2 production control system and prevents the loss of non-critical vehicle systems.
The Yuasa Yu-Fit battery configurator tool allows the configuration process to be carried out on a
growing number of vehicles equipped with new technology smart charge and ISS systems.
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
Before the Yuasa Yu-Fit battery configurator can
be used it must be registered & the supporting
application suite installed on your computer.
Refer to Yu-Fit “Registration & Application
Suite Installation Guide” for more information.

Note
The battery configuration procedure that the Yuasa Yu-Fit is capable of varies dependent on the
vehicle manufacturer and sophistication of the systems installed
on the vehicle.
Vehicles allowing limited access with the Yuasa Yu-Fit will only allow the configuration of the
correct specification replacement battery.
Vehicles allowing enhanced access with the Yuasa Yu-Fit will allow the configuration of either
correct /incorrect specification replacement batteries.
Based on this, the number of configuration steps may also vary and the level of information
required to carry out a successful battery configuration procedure will differ and may include:
• Is the new battery equivalent to the old one in both technology and performance?
• The name of the battery manufacturer
• The technology of the new battery
• The Ah capacity of the new battery
WARNING:
ALWAYS ENSURE THAT THE CORRECT TYPE AND SPECIFICATION
OF BATTERY IS INSTALLED ON THE VEHICLE
Select and confirm the correct battery data with OK
Wait for any fault codes to be cleared and conformation that the battery configuration process
has been successfully concluded before turning OFF the ignition and disconnecting the Yuasa
Yu-Fit from the vehicle.
